NCERT MOST IMPORTANT QUESTIONS ON THE p-BLOCK ELEMENT

1.Why the elements of group 13 are called p-block elements?

Ans.Group 13 elements are called p-block elements because the last electron is present in the p-orbital (np1). The valence shell configurations are B (2s2 2p1), Al (3s2, 3p1), Ga (4s2, 4p1), In (5s5p1) Tl (6s6p1)


2.The elements B, Al, Ca, In and Tl are placed in the same group of the periodic table. Give reason.

Ans. The elements B, Al, Ga, In and Tl are placed in the same group of the periodic table because each one has the same number of electrons (ns2 np1) in its valance shell.


3.Aluminium forms in not formed why?

Ans. Due to presence of vacant d-orbital’s, Al can expand its octet to form bonds with six fluoride ions whereas B cannot. Boron does not have d-orbital’s.


4.The atomic radius of Ca is less than that of Al. Why?

Ans. This is due to the variation in the inner core of the electronic configuration. The presence of additional 10 d-electrons offer only poor screening effect for the outer electrons from the increased nuclear charge in gallium.


5.C and S are always tetravalent but Ge, Sn And Pb show divalency. Why?

Ans. Inert pair is more prominent as we move down the group in p – block elements. Ge, Sn and Pb show divalency due to inert pair effect.


6.Some halides of group 14 elements form complexes of the type . Give reason.

Ans. The halides of the elements having vacant d-orbital’s can form complexes like because in such a case the central atom can increase its coordination number from 4 to 6 due to availability of vacant d–orbital’s.


7.is lead known whereas not. Give reason.

Ans. The main reasons are that

(i) Six large chloride ions cannot be accommodated around Si4+ due to limitation of its size.

(ii) Interaction between lone pair of chloride ion and Si4+ is not very strong.


8.PbIdoes not exist. Why?

Ans.PbI4 does not exist because Pb – I bond initially formed during the reaction does not release enough energy to unpair 6s2 electrons and excite one of them to higher orbital to have four unpaired electrons around lead atom.


9.Why is carbon different from other member of the group?

Ans. Carbon differs from rest of the members of its group due to its smaller size, higher electro negativity, higher ionization enthalpy and unavailability of d-orbital’s.


10.Why does the covalence of carbon not expand beyond four?

Ans. In carbon, only s and p orbital’s are available for bonding and therefore it can accommodate only four pairs of electrons around it. This limit the maximum covalence to four whereas other members can expand their covalence due to the presence of d-orbital’s.


11.Why does carbon show different allotropic forms?

Ans. Due to property of catenation and pπ – pπ bond formation Carbon is able to show different allotropic forms.


12.Silicon has no allotropic form analogous to graphite. Why?

Ans. Due to large size. Si has little or no tendency for pπ – pπ bonding. Whereas carbon atom forms easily pπ – pπ bonds due to smaller size in graphite structure. Hence, Si does not exhibit graphite structure.


13.Why does graphite conduct electricity?

Ans. Graphite forms hexagonal ring and undergoes sp2 hybridization. The electrons are delocalized over the whole sheet. Electrons are mobile and therefore graphite conducts electricity over the sheet.


14.Graphite is used as lubricant. Give reason.

Ans. Graphite has sp2 hybridized carbon with a layer structure due to wide separation and weak inter – layer bonds the two adjacent layers can easily slide over each other. This makes graphite act as a lubricant.


15.How are silicones manufactured?

Ans.They are manufactured by hydrolysis of chlorosilanes –

where R is a methyl or phenyl group.

Memories of Childhood SUMMARY NCERT SOLUTION CLASS 12TH ENGLISH VISTAS | EDUGROWN NOTES

Reading with Insight
Q1. The two accounts that you read above are based in two distant cultures. What is the commonality of theme found in both of them?

ANSWER:
The autobiographical accounts included in the “Memories of Childhood” are by two women from socially marginalized sections in two distant cultures of the world. One highlights the evil practice of racial prejudice while the other talks about the hierarchical Indian caste system and untouchability. The first part traces how the author, a Native American, was victimized at the hands of the European staff of her boarding school. The second account gives a picture of the hardships and humiliations faced by the Indian ‘Dalits’ from the eyes of a third standard student.
Although they are set in different cultures, both the stories share a similar theme. They show the sufferings and oppression faced by their respective communities. The practice of social stratification is rebuked by both the authors. Zitkala-Sa’s hair was “shingled” at the behest of Europeans who considered themselves superior to the Native American. On the other hand, Bama witnessed untouchability being practiced openly where people from ‘lower castes’ were considered impious and were not even allowed to touch the people from the upper castes. From a very young age, both Zitkala-Sa and Bama start protesting and resisting in their own ways.

Q2. It may take a long time for oppression to be resisted, but the seeds of rebellion are sowed early in life. Do you agree that injustice in any form cannot escape being noticed even by children?

ANSWER:
However, their keen observant eye is capable enough to notice any form of injustice and discrimination. When subjected to such evil practices, their sensitive minds and hearts are deeply affected. Perplexed, they often resist in their own simple ways.
In the lesson, the two girls describe their encounters with inequality. Zitkala-Sa, in the very first line reports that her first day in school was “bitter-cold”. For her, it not only describes the weather, but also represents the atmosphere of the boarding school. The overly disciplined students of the school and the European staff were unfriendly or “cold” towards her, and the vain struggle against her hair being shingled was a “bitter” experience for her. On the other hand, Bama walked on her brother’s footsteps to protest against the practice of untouchability through education. She studied wholeheartedly to reach a position where people would forget her “caste” and feel proud to befriend her.

Q3. Bama’s experience is that of a victim of the caste system. What kind of discrimination does Zitkala-Sa’s experience depict? What are their responses to their respective situations?

ANSWER:
While Bama was subjected to caste discrimination and untouchability, Zitkala-Sa was a victim of racial prejudice. Zitkala-Sa was packed off to a European missionary school where, being a local tribal, she was looked down upon. Her precious, long and heavy hair, which was her pride, was shingled. She tried to resist with all her might but, ultimately, she was forced to give up her struggle. On the contrary, Bama, who witnessed the malpractice of untouchability, decided to blur the difference of castes with the light of education. Under the guidance and supervision of her elder brother, she judiciously utilized her anger and sense of rebellion to study hard and outwit any form of prejudice. She understood that a social change would be possible only if these so-called lower castes make an effort to study and, thus, make progress.
It can easily be noticed that though both the protagonists tried to protest against the injustice they faced, the paths they chose are remarkably different. Through this journey of rebellion, Zitkala-Sa is forced to give in; on the contrary, Bama successfully implemented her brother’s advice to finally top in her class. While Zitkala-Sa continued to rebel by criticizing the evils of racial prejudice through her works, Bama opted for a more subtle way to carry forth her silent yet effective remonstration.

SHORT ANSWER TYPE QUESTIONS :


Q1. What does Zitkala-Sa remember about her ‘first day in the land of apples’?
  ANSWER: It was a bitter-cold day. The snow still covered the ground. The trees were bare. A large bell rang for breakfast. Its loud metallic sound crashed through the belfry overhead and penetrated into their sensitive ears.

Q2. How did Zitkala-Sa react to the various sounds that came when the large bell rang for breakfast?
ANSWER:  The annoying clatter of shoes on bare floors disturbed the peace. There was a constant clash of harsh noises and an undercurrent of many voices murmuring an unknown tongue. All these sounds made a bedlam within which she was securely tied. Her spirit tore itself in struggling for its lost freedom.

Q3. Where were the girls taken and how ?
Ans. The girls were marching into the dining room in a line. The Indian girls were in stiff shoes and tightly sticking dresses. The small girls wore sleeved aprons and shingled hair. They did not seem to care that they were indecently dressed.

Q4. “I felt like sinking to the floor”, says Zitkala-Sa. When did she feel so and why ?
ANSWER: It was her first day at school. She was marching into the dining room with other girls in a line. She walked noiselessly in her soft moccasins. But she felt that she was immodestly dressed, as her blanket had been removed from her shoulders. So, she felt like sinking to the floor.

Q5. “But this eating by formula was not the hardest trial in that first day”, says Zitkala-Sa. What does she mean by ‘eating by formula’ ?
ANSWER:  The ringing of a large bell summoned the students to the dining room. Then a small bell tapped. Each pupil drew a chair from under the table. Then a second bell was sounded. All were seated. A man’s voice was heard at one end of the hall. They hung their heads over the plates. The man ended his mutterings. Then a third bell tapped. Everyone picked up his/her knife and fork and began eating.

Q6. How did Zitkala-Sa find the ‘eating by formula’ a hard trial?
ANSWER:  She did not know what to do when the various bells were tapped and behaved unlike others. When the first bell rang, she pulled out her chair and sat in it. As she saw others standing, she began to rise. She looked shyly around to see how chairs were used. When the second bell was sounded, she had to crawl back into her chair. She looked around when a man was speaking at the end of the hall. She dropped her eyes when she found the paleface woman looking at her. After the third bell, others started eating, but she began to cry.

Q7. What did Judewin tell Zitkala-Sa? How did she react to it?
ANSWER: Judewin knew a few words of English. She had overheard the paleface woman. She was talking about cutting their long, heavy hair. Judewin said, “We have to submit, because they are strong.” Zitkala-Sa rebelled. She declared that she would not submit. She would struggle first.

Q8. ‘Why, do you think, was Zitkala-Sa so opposed to cutting of her hair?
ANSWER:  Zitkala-Sa had heard from her mother that only unskilled warriors, who were captured, had their hair shingled by the enemy. Among their people, short hair was worn by mourners, and shingled hair by cowards. Since she was neither, she was dead against cutting of her long hair.

Q9. How did Zitkala-Sa try to avoid the inevitable loss of her long hair ?
ANSWER:  She crept up the stairs and passed along the hall. She did not know where she was going. She turned aside to an open door. She found a large room with three white beds in it. The windows were covered with dark green curtains. She went to the comer farthest from the door and crawled under the bed in the darkest corner.

Q10. How was the search made for Zitkala-Sa?
ANSWER:  First, they called out her name in the hall in loud voices. Then the steps were quickened. The voices became excited. The sounds came nearer. Women and girls entered the room. They opened closet doors. They peeped behind large trunks. Someone threw up the curtains. The room was filled with sudden light. Someone stooped, looked under the bed and found her there.

Q11. How was Zitkala-Sa treated on being traced from her hiding place ?
ANSWER: Zitkala-Sa was dragged out. She tried to resist by kicking and scratching wildly. But she was overpowered. She was carried downstairs and tied fast in a chair. She cried aloud and kept shaking her head.

Q12. What did Zitkala-Sa feel when her long hair was cut? ‘
ANSWER: When she heard them remove one of her thick braids, she lost her spirit. She had suffered utmost indignities there. People had stared at her. She had been tossed about in the air like a wooden puppet and now her long hair was shingled like a coward’s. In her anguish, she moaned for her mother. She felt herself as one of the many little animals driven by a herder.

Q13. Which words of her brother made a deep impression on Bama? [Delhi 2014]
ANSWER:  While returning home, Bama’s elder brother told her that although people do not get to decide the family they are bom into, they can outwit the indignities inflicted upon them. It left a deep impression on her.

Q14. Name some of the novelties and oddities in the streets that attracted Bama?
ANSWER:  These included the performing monkey, the snakecharmer’s snake, the cyclist who had kept on biking for three days, the spinning wheels, the Maariyaata temple and the huge bell hanging there. She also noticed the pongal offerings being cooked in front of the temple.

Q15. What were the articles in flit stalls and shops that fascinated Bama?
ANSWER:  She saw the dried fish stall by the statue of Gandhiji; the sweet stall, and the stall selling fried snacks. There were many other shops next to each other. Then there was the narikkuravan huntergypsy. He had his wild lemur in cages. He sold needles, clay beads and instruments for cleaning out the ears.

Q16. What sort of shows or entertainments attracted the passers-by?
ANSWER:  Sometimes various political parties put up a stage. They addressed people through their mikes. There might be a street play, a puppet show, or a “no magic, no miracle” stunt performance. There was some entertainment or the other happening there from time to time.

Q17. Which actions of the people would Bama watch keenly in the bazaar?
ANSWER: She watched how each waiter in the various coffee clubs would cool the coffee. He would lift a tumbler high up. Then he would pour its contents into another tumbler held in the other hand. She observed how the people, chopping up onion, would turn their eyes elsewhere to avoid irritation in their eyes.

Q18. Why was Zitkala-Sa in tears on the first day in the land of apples? [All India 2014]
ANSWER:  On the first day in the land of apples, Zitkala-sa was in tears. The main reason of tears was that her hair was mercilessly cut. She had heard from her mother that only unskilled warriors, who were captured, had their hair shingled by the enemy. That is why she shook her head in resistance.

Q19. Which fruit or sweet delicacies did she observe in the bazaar?
ANSWER: There would be mango, cucumber, sugar-cane, sweet potato, palm-shoots, gram, palm- syrup, palm-fruit, guavas and jack-fruit, according to the season. She would see people selling sweet and savoury fried snacks, payasam, halva, boiled tamarind seeds and iced lollies each day.

Q20. How were the threshing proceedings going on in the corner of the street?
ANSWER: There was a threshing floor set up in the comer of the street. People were hard at work. They were driving cattle in pairs, round and round, to tread out the grain from the straw. The animals were muzzled so that they couldn’t eat the straw. Bama stood there watching for fun. The landlord was watching the proceedings. He was seated on a piece of sacking spread over a stone ledge.

Q21. What, do you think, made Bama want to double up and shriek with laughter?
ANSWER:  Bama saw an elder of their street coming along from the direction of the bazaar. He was a big man. He was carrying a small packet, holding it out by its string. The manner in which he was walking along made Bama want to double up. She wanted to shriek with laughter at the funny sight.

Q22. How did the elder approach the landlord and offer him the packet?
ANSWER:  The elder went straight up to the landlord. Then he bowed low and extended the packet towards him. He cupped the hand that held the string with his other hand. The landlord opened the parcel and began to eat the vadais.

Q23. What explanation did Bama’s elder brother Annan give her about the elder’s “funny” behaviour?
ANSWER:  Annan told Bama that the man was not being funny when he carried the package by the string for his landlord. The upper caste people believed that others must not touch them. If they did, they would be polluted. That was the reason why he (the elder man) had to carry the package by its string.

Q24. How did Bama react on learning about untouchability?
ANSWER:  Bama became sad on listening how the upper caste people behaved towards low caste persons like them. She felt provoked and angry. She wanted to touch those vadais herself. She wondered why their elders should run errants for the miserly rich upper caste landlords and hand them over things reverently, bowing and shrinking all the while.

Q25. How did the landlord’s man behave with Annan?
  ANSWER: The man thought that Annan looked unfamiliar, and asked his name respectfully. However, his manner changed as soon as Annan told his name. The man immediately asked the name of the street he lived in. The purpose was to identify his caste from the name of the street.

Q26. How, according to Annan, was the caste system discriminatory? How can one overcome the indignities?
ANSWER: Annan said that the lower caste people were never given any honour or dignity or respect. They were deprived of all that. Thus, the caste system was discriminatory. But, if they studied and made progress, they could throw away those indignities.

Long Answer type Question:

Q1. Why did Zitkala-Sa feel oppressed in new establishment?
  ANSWER: Since the day, the author was taken away from her mother, she had suffered extreme indignities. People had stared at her. She had been tossed about in the air like a wooden puppet. Her blanket had been removed from her shoulders. She felt that she was immodestly dressed. She was so shocked and oppressed that she felt like sinking to the floor. Later, her soft moccasins were taken away. These were the traditional footwear of the local Indian American. They were replaced by squeaking shoes. She saw other Indian girls in stiff shoes and tightly sticking dresses. The small girls wore sleeved aprons and shingled hair. The worst indignity she suffered was the cutting of her long hair. The coward’s shingled hair made her moan with anguish. She felt she was not a human being but one of the little animals driven by a herder. The systematic erosion of their culture and disrespect to women was quite oppressive.

Q2. “But this eating by formula was not the hardest trial in that first day”, says Zitkala-Sa.What do you understand by ‘eating by formula’ and how did she find it a hard trial?
ANSWER:  There was a fixed procedure laid down for breakfast. Zitkala-Sa calls it ‘eating by formula’. The ringing of a large bell summoned the inmates to the dining room. Boys and girls entered the dining room in lines from separate doors. Then a small bell was tapped. Each of the pupil drew a chair from under the table. The writer also did so. She supposed this act meant they were to be seated. So she slipped into the chair. She found others standing. Just when she began to rise, looking shyly, the second bell sounded and all sat down. Then she heard a man’s voice at one end of the hall. She looked around to see him. But all the others hung their heads over their plates. She found the paleface woman watching her. When the man ceased his mutterings, a third bell was tapped. Everyone picked up his knife and fork and began eating. She began to cry. She was so afraid that she could not do anything further. Her discomfiture was caused by her unfamiliarity with the procedure. However, she found it a difficult experience—a sort of trial.

Q3.“I will not submit! I will struggle first!” says Zitkala-Sa. What was she going to resist and why? What efforts did she make and what was the outcome?
ANSWER: Zitkala-Sa had long, heavy hair. Her Mend Judewin had overheard the paleface woman talk that their hair was to be shingled. Zitkala-Sa decided to resist it. Among their people, short hair was worn by mourners, and shingled hair by cowards. Unskilled warriors captured by the enemy also got their hair shingled. Cutting a woman’s long hair was thus against their tradition and culture.
She tried to avoid it. She crept up the stairs quietly and hid herself under the bed in a room with dark green curtains. She had crawled to the comer farthest from the door and lay close in the darkest comer. Soon she heard her name shouted in the hall. Then the steps were quickened and voices became excited. Women and girls entered the room. They opened closet doors and peeped behind large trunks. Someone threw up the curtains. The room was filled with sudden light. Someone stooped, looked under the bed and saw her there. She was dragged out though she resisted by kicking and scratching wildly. She was carried downstairs and tied fast in a chair. She cried aloud and kept shaking her. head till the scissors cut her long hair.

Q4. What diversions in the streets, shops and the bazaar attracted Bama, tethered her legs and stopped her from going home?
ANSWER:  There were many novelties and oddities that attracted Bama. These included the performing monkey, the snakecharmer’s snake, the narikkuravan huntergypsy’s wild lemur in cages, -the cyclist who had been pedalling for three days, the spinning wheels, the Maariyaata temple and its huge bell. She also noticed the pongal offerings being cooked in front of the temple. There was a dried fish stall near the statue of Gandhiji. There was a sweet stall and a stall selling Med snacks. There were many shops next to each other.
The public meetings of political parties, street plays, puppet shows, and stunts were other entertainments. She would watch how the waiters would pour coffee from a tumbler held high to another low down to cool it. Then she saw people who chopped onion kept their eyes to another side to avoid irritation. She admired the various fruits that came to the bazaar according to the season. She also noticed people selling sweet and savoury fried snacks. These were the usual scenes and sights that tethered her legs and stopped her from going home.

Q5. How did Bama react to the threshing proceedings in a corner of their street and the spectacle of a big man carrying a packet by its string ?
ANSWER:  Bama watched the threshing floor, people working with cattle to tread out the grain and the muzzled animals with a child’s curiosity. She stood there watching the fun. The landlord was also watching the proceedings. He was seated on a piece of sacking spread over a ledge.
Then she saw a big man, an elder of her street, coming along from the direction of the market. The manner in which he was walking along made her want to double up. She wanted to shriek with laughter at the sight of such a big man carrying a small packet by its string, without touching. She thought that the package might come undone and its contents fall out. ‘
Then the elder went straight upto the landlord, bowed low and extended the packet towards him. He cupped the hand that held the string with his other hand. The landlord opened the parcel and began to eat the vadais. She found the whole scene quite funny and amusing. She related it to her brother in all its comic details.

Q6. How did Bama’s brother explain the elder’s behaviour to her? What was her immediate reaction?
ANSWER:  Bama’s elder brother, Annan, told her that the big man was not being funny when he carried the package by the string for his landlord. The upper caste people believed that others must not touch them. If they did so, they (people belonging to upper caste) would be polluted. That was why he did not touch the contents but held the packet by its string. Bama didn’t want to laugh any more now. She felt terribly sad. She could not understand how the vadai, first wrapped in a banana leaf and then parcelled in a paper, would become disgusting if one of them held that package in his hands. She felt so provoked and angry that she wanted to touch those vadais herself straightaway. She wondered why they had to fetch and carry for these people. She was infuriated that an important elder of theirs went meekly to the shops to fetch snacks and then handed them over reverently, bowing and shrinking to the fellow who sat there and stuffed them in his mouth. She felt that they too were human beings. Their people should not do petty jobs for the miserly rich upper castes. They should work in their fields, take home their wages and leave it at that.

Q7. What indignities did the caste system heap on the lower castes? How could they end the discrimination? How did Bama react to her brother’s advice?
ANSWER: According to Annan, the caste system was highly discriminatory. It put the lower castes in a very disadvantageous position. They were never given any honour, dignity or respect. They were deprived of all that. The only way to end this social discrimination was self¬improvement. They should study hard and make progress. Then they could throw away all those indignities.
He advised Bama to study with care and learn all that she could. If she was always ahead in her lessons, people would come to her of their own accord and attach themselves to her. The words “work hard and learn” became the guiding principles of Bama’s life. She studied hard with all her breath and being. She was almost in a frenzy. She stood first in her class and, because of that, many people became her friends. This was the beginning of her illustrious career.

Q8. What oppression and discrimination did Zitkala-Sa and Bama experience during their childhood? How did they respond to their respective situations?
ANSWER:  Zitkala-Sa was a victim of social and cultural oppression by the victors who had overpowered them by their sheer strength. They were prejudiced towards Native American culture and women.
They adopted force and oppression to compel the natives to shed their age-old traditions and customs. The cutting of the long hair of Zitkala-Sa is a symbol of their oppression. She opposed this prejudice and oppression by rebelling against it. She protested with all her strength.
Bama was a victim of caste system. She had seen, felt and experienced the evils of untouchability when she was studying in the third standard. She felt humiliated by what it was. She struggled hard against this social discrimination. She studied hard and topped in her class. Many students became her friends.
Thus, both Zitkala-Sa and Bama fought the existing circumstances with courage and determination and ended the prejudice, discrimination and oppression.

NCERT MOST IMPORTANT QUESTIONS CLASS – 11 | CHEMISTRY IMPORTANT QUESTIONS PART-2 | CHAPTER -3 | THE s-BLOCK ELEMENTS | EDUGROWN |

In This Post we are  providing Chapter-3 THE s-BLOCK ELEMENTS NCERT MOST IMPORTANT QUESTIONS for Class 11 CHEMISTRY which will be beneficial for students. These solutions are updated according to 2021-22 syllabus. These MCQS  can be really helpful in the preparation of Board exams and will provide you with a brief knowledge of the chapter.

NCERT MOST IMPORTANT QUESTIONS ON THE s-BLOCK ELEMENTS

Question 1.
Why the solubility of alkaline metal hydroxides increases down the group?

Answer:
If the anion and the cation are of comparable size, the cationic radius ‘vill influence the lattice energy. Since lattice energy decreases much more than the hydration energy with increasing ionic size, solubility will increases as we go down the group. This is the case of alkaline earth metal hydroxides.

Question 2.
Why the solubility of alkaline earth metal carbonates and sulphates decreases
down the group?

Answer:
If the anion is large compared to the cation, the lattice; energy will remain almost constant within a particular group. Since the hydration energies decrease down the group, solubility will decrease as found for alkaline earth metal carbonates and sulphates.

Question 3.
Why cannot potassium carbonate be prepared by the SOLVAY process?

Answer:
Potassium carbonate cannot be prepared by the SOLVAY process because potassium bicarbonate (KHCO3) is highly soluble in water, unlike NaHCO3 which was separated as crystals. Due to its high solubility KHCO3 cannot be precipitated by the addition of ammonium bicarbonate to a saturated solution of KCl.

Question 4.
What are the main uses of calcium and magnesium?

Answer:
Main uses of calcium:

  1. Calcium is used in the extraction of metals from oxides which are difficult to reduce with carbon.
  2. Calcium, due to its affinity for O2 and N2 at elevated temperatures, has often been used to remove air from vacuum tubes.

Main uses of Magnesium:

  1. Magnesium forms alloys with Al, Zn, Mn and Sn. Mg-Al alloys being light in mass are used in aircraft construction.
  2. Magnesium (powder and ribbon) is used in flashbulbs, powders incendiary bombs and signals.
  3. A suspension of Mg(OH)2 in water is used as an antacid in medicine.
  4. Magnesium carbonate is an ingredient of toothpaste.

Question 5.
What is meant by the diagonal relationship in the periodic table? What is it due to?

Answer:
It has been observed that some elements of the second period show similarities with the elements of the third period situated diagonally to each other, though belonging to different groups. This is called a diagonal relationship.
The s-Block Elements Class 11 Important Extra Questions Chemistry 2
The cause of the diagonal relationship is due to the similarities in properties such as electronegativity, ionisation energy, size etc. between the diagonal elements. For example on moving from left to right across a period, the electronegativity increases, which on moving down a group, electronegativity decreases. Therefore on moving diagonally, two opposing tendencies almost cancel out and the electronegativity values remain almost the same as we move diagonally.

Question 6.
Why is the density of potassium less than that of sodium?

Answer:
Generally, in a group density increases with the atomic number, but potassium is an exception. It is due to the reason that the atomic volume of K is nearly twice Na, but its mass (39) is not exactly double of Na (23). Thus the density of potassium is less than that of sodium.

Question 7.
The hydroxides and carbonates of sodium and potassium are easily soluble in water while the corresponding salts of magnesium and calcium are sparingly soluble in water. Explain.
Answer:
Sodium and potassium ions (Na+ and K+) are larger than the corresponding Mg2+ and Ca2+ ions. Due to this lattice energy of Mg(OH)2, Ca(OH)2, MgCO3 and CaCO3. (Lattice energy is defined as the energy required to convert one mole of the ionic lattice into gaseous ions.

Thus lattices with smaller ions have higher lattice energies). The hydration energies of Mg2+ and Ca2+ are higher than Na+ and K+ because of their smaller sizes. But the difference in lattice energies is much more. Therefore, the hydroxides and carbonates of Mg2+ and Ca2+ are insoluble in water because of their higher lattice energies.

Question 8.
Why is it that the s-block elements never occur in free state/nature? What are their usual modes of occurrence and how are they generally prepared?

Answer:
The elements belonging to the s-block in the periodic table (i.e. alkali and alkaline earth metals) are highly reactive because of their low ionisation energy. They are highly electropositive forming positive ions. So they are never found in a free state.

They are widely distributed in nature in the combined state. They occur in the earth’s crust in the form of oxides, chlorides, silicates and carbonates.

Generally, a group I metals are prepared by the electrolysis of fused solution.
For example:

1. The s-Block Elements Class 11 Important Extra Questions Chemistry 3
At cathode: Na+ + e → Na
At anode: Cl → Cl + e
Cl + Cl → Cl2

2. KOH ⇌ K+ + OH
At cathode: K+ + e– → K
At anode: 4OH → 4OH + 4e
4OH → 2H2O + O2
or
4OH → 2H2O + O2 + 4e
These metals are highly reactive and therefore cannot be extracted by the usual methods, because they are strong reducing agents.

Question 9.
Explain what happens when

(i) Sodium hydrogen carbonate is heated.
Answer:

Q10.List the responsible factors which enabled the Umayyad to come to power.
ANSWER:
The Umayyad dynasty was founded by Muawiya in 661 CE. Between the years 661- 750 all Caliphs were from Umayyad dynasty. Following factors enabled Umayyads to coming into power.

  • With the territorial expansion, the Umma unity was broken up.
  • Conflicts over the distribution of resources began to increase among the Umma.
  • The Meccan character of the early Islamic state by Uthman, who packed his administration with his own men, to his exclusion of other tribes men, to secure greater central.

The rifts deepened and after his assassination Muwaiya successfully made him the next Caliph, to exclusion of Ali’s son Hussain, founding Umayyad dynasty.


Q11.Write an evolutionary note on the regime of the fourth Caliph, Ali.
ANSWER:
Ali was the fourth Caliph. He fought two wars against those who were representing the aristocracy of Mecca. As a result of these wars, the rifts among the Muslims depened. Later on his supporters and enemies got divided into two sects. These two sects were: Shias and Sunnis. Ali established himself at Kufar and defeated Aisha’s (Muhammad’s wife) army in the Battle of Camel in 657.

Although Ali won this war but he was unable to suppress the group led by Muawiya, a kinsman of Uthman and the governor of Syria. Then he fought another war with him at Siffin, which ended in a truce. After the War of Siffin, Ali’s followers got divided into two groups. Some remained loyal to them, while others who left them came to be known as Kharjis.


Q12.During Abbasids, Arab influence began to decline. Why?
ANSWER:
During Abbasids, the Arab influence began to decline on account of the following reasons:

Q4.“Throughout the history of human beings their interest in religion often went hand in hand”. Justify the statement by giving examples.
ANSWER:

  • From the very beginning, evidence has been traced out that Indian traders traveled to the different countries of South East Asia for trade in gold, tin, spices, etc. While travelling and trading to these nations they also took with them the ideas and practices of the religion. The ideology of Buddhism and Hinduism became the part and parcel of their culture. These two religions were adopted by the people of Jawa, Cambodia, Sri Lanka, etc.
  • The Arab traders in the medieval period established their trade relations with India and many other countries of Europe and Asia. They carried with them the ideas of newly founded religion, i.e. Islam. Due to its simplicity in principle, Islam was adopted by many Indians and in the same way it spread into Spain, Syria, Iran and Iraq.
  • The traders of the western countries, i.e. the traders of England, Holland, France, etc. spread their trading relations in many countries. They brought with them the ideas of Christianity. While trading, they also spread Christianity into different countries. Today this religion is adopted by the people of different countries of Asia and Africa.Keeping the above examples in mind, we can conclude that throughout the history human being’s interest in religion went hand in hand.


Q5.Discuss the main sources of income of the state in detail.
Or
What do you know about agriculture of the Central Islamic lands?
ANSWER:
Agricultural was the main occupation of the settled population, since long. It also remained a major occupation in newly acquired territories. The bulk of income of the state was derived from the agricultural land.

Land was owned by the small and big farmers and in some cases by the state. After Islamic conquests, big estates were abandoned and acquired by the state. Later on these states were handed over to Muslim elites. The chief among them were the members of Khalifa’s (Caliph’s) army.

The land conquered by the Arabs, which remained in the hands of the owners were subjected to a tax, called Kharaj, varied from 1/2 to 1/5th of the produce. While the land cultivated by the Muslims were levied 1/10th of tax, known as ushr as land
revenue. When non-Muslims started converting to Islam, the land revenue income fell dramatically. To meet the shortfall, the Caliphs decided to discourage the conversions and later adopted a uniform land revenue policy.

After 10th century, the state authorised its officials to claim salaries from the agricultural territories called Iqtas (The person who held the Iqtas came to be known as Iqtadars). Agricultural prosperity and political stability went hand-in-hand. To ensure agricultural prosperity it took several measures such as canals were constructed, dams were built, the digging of wells, etc. were done. Tax concessions were granted to those people who brought land under cultivation. By the initiatives of peasants and state support the agriculture began to increase. Many new crops such as cotton, oranges, bananas, watermelon, spinach and brinjal began to grow and even exported to Europe.

ANSWER:
The general prosperity was especially marked in the East where population was still expanding till the sixth century, despite the impact of the plague which affected the Mediterranean in the 540’s. In the West, by contrast, the empire fragmented politically as Germanic groups from the North took over all the major provinces and established kingdoms that are best described as ‘Post-Roman’.


Q4.Who was Columella?
ANSWER:
Columella, a first-century writer who came from the south of Spain, recommended that landowners should keep a reserve stock of implements and tools, twice as many as they needed to improve the better situation of laborers.


Q5.What had occurred after Prophet Muhammad’s death by 642?
ANSWER:
By 642, barely ten years after Prophet Muhammad’s death, large parts of both the Eastern Roman and Sasanian empires had fallen to the Arabs in a series of confrontations. Though, those conquests, which eventually a century later extended up to Spain, Sind and Central Asia, began in fact with the subjection of the Arab tribes by the emerging Islamic state, first within Arabia and then in the Syrian desert on the fringes of Iraq.


Q6.What is Frankincense?
ANSWER:
Frankincense is the European name for an aromatic resin used in incense and perfumes. It is tapped from Boswellia trees by slashing the bark and allowing the exuded resins to harden. The best quality of it came from the Arabian peninsula.


Q7.Define the territorial position of the Roman empire.
ANSWER:
The continents of Europe and Africa are separated by a sea, called the Mediterranean that stretches all the way from Spain in the west to Syria in the east and it was the heart of Rome’s empire. To the north, the boundaries of the empire were formed by two great rivers, the Rhine and the Danube and to the south, by the huge expanse of desert called the Sahara. This vast stretch of territory was the Roman empire.


Q8.What does the term ‘Republic’ refer to in the history of the Roman empire?
ANSWER:
The Republic was the name for a regime in which the power lay with the Senate, a body dominated by a small group of wealthy families who formed the ‘nobility’. The Republic represented the government of the nobility, exercised through the body called the Senate. The Republic lasted from 509 BCE to 27 BCE, when it was overthrown by Octavian, the adopted son and heir of Julius Caesar.


Q9.How army was the important key institution of imperial rule in the Roman empire?
ANSWER:
The Roman had a paid professional army where soldiers had to put in a minimum of 25 years of service. The existence of paid army was a distinctive feature of the Roman empire. It was an organized body in the empire by the fourth century and had the power to determine the fate of emperors. The soldiers would trouble for better wages and service conditions. These agitations often took the form of revolt.


Q10What was the policy of taxation in the Roman empire?
ANSWER:
The great urban centers of the Mediterranean were the base of the grand system of the Roman empire. It was through the cities that ‘government’ was able to tax the regional countrysides which generated much of the wealth of the empire. The local upper classes actively collaborated with the Roman state in administering their own territories and raising taxes from them.


Q11.How had the Roman survived their lives during famine?
ANSWER:
The famine for many successive years in many provinces had clearly displayed for men of any understanding the effect of malnutrition in generating illness. So the city- dwellers, collected and stored enough grain for the next year immediately after the harvest, carried off all the wheat, barley, beans and lentils, and left to the peasants various kinds of pulses-after taking quite a large proportion of these to the city. After consuming what was left in the course of the winter, the country people had to resort to unhealthy foods in the spring. They ate twigs, shoots of trees and bushes and roots of inedible plants.


Q12.What was the typical form of marriage in the third century of Rome?
ANSWER:
Males married in their late twenties or early thirties; while women were married in the late teens or early twenties. There was an age gap between husband and wife. As a result, there was inequality. Marriages were generally arranged, and there is no doubt that women were often subject to domination by their husbands. Divorce was relatively easy and needed no more than a notice of intent to dissolve the marriage by either husband or wife.


Q13.How was the economic condition in the early Roman empire?
ANSWER:
The empire had a substantial economic infrastructure of harbors, mines, quarries, brickyards, olive oil factories, etc. Wheat, wine and olive-oil were traded and consumed in huge quantities, and they came mainly from Spain, the Gallic provinces, North Africa, Egypt and to a lesser extent, Italy where conditions were suitable for these crops. Liquids like wine and olive oil were transported.


Q14.How had the Roman empire been considered the wealthiest empire in case of fertility of land?
ANSWER:
The Roman empire included many regions that had a reputation of exceptional fertility. Campania in Italy, Sicily, the Fayum in Egypt, Galilee, Byzacium (Tunisia), Southern Gaul (called Gallia Narbonensis) were among the most densely settled or wealthiest parts of the empire, like Strabo and Pliny. The best kinds of wine came from Campania. Sicily and Byzacium exported large quantities of wheat to Rome. Galilee was densely cultivated, and Spanish olive oil came mainly from numerous estates {fundi) along the banks of the river Guadalquivir in the south of Spain.

Long Answer Type Question:


Q1.What do you think about the importance of Latin and Greek languages in the Roman empire?
ANSWER:
“Greek East” and “Latin West” are the terms that are used to distinguish between the two parts of the Greco-Roman world, especially the eastern regions where Greek was the lingua franca, and the western parts where Latin filled this role. During the Roman empire a division had persisted between Latin and Greek speaking areas. This division was encouraged by administrative changes in the empire’s structure between the third and fifth centuries, which led ultimately to the establishment of separate Eastern and Western Roman empires.

Latin and Greek were the dominant languages of the Roman empire. The language of the ancient Romans was Latin, which served as the “language of power”. Latin was omnipresent in the Roman empire as the language of the law courts in the West, and of the military everywhere. A great number of Roman citizens would have lacked Latin, though they were expected to acquire at least token knowledge, and Latin remained a marker of “Romanness”.

Greek had become a shared language around the Eastern Mediterranean and into Asia Minor as a consequence of the conquests of Alexander the Great. The “linguistic frontier” dividing the Latin West and the Greek East passed through the Balkan peninsula. Educated Romans, particularly those of the ruling elite, studied and often achieved a high degree of fluency in Greek, which was useful for diplomatic communications in the East even beyond the borders of the empire. The use of Greek at international level was one condition that enabled the spread of Christianity, as indicated for example by the choice of Greek. With the dissolution of the empire in the West, Greek became the dominant language of the Eastern Roman empire.


Q2.What do you know about Augustus? Explain.
ANSWER:
Augustus was the founder of the Roman empire and its first Emperor, ruling from 27 BCE until his death in 14 CE. He was born Gaius Octavius into an old and wealthy equestrian branch of the Plebeian Octavii family. In 44 BCE he was adopted posthumously by his maternal great-uncle Gaius Julius Caesar following Caesar’s assassination. Together with Mark Antony and Marcus Lepidus, he formed the Second Triumvirate to defeat the assassins of Caesar. Following their victory at Phillipi, the Triumvirate divided the Roman Republic among them and ruled as military dictator.

Lepidus was kept into exile and stripped of his position and Antony committed suicide following his defeat at the Battle of Actium by Augustus in 31 BC.

After the demise of the Second Triumvirate, Augustus restored the outward facade of the free Republic, with governmental power vested in the Roman Senate, the executive magistrates, and the legislative assemblies. In reality, however, he retained his autocratic power over the Republic as a military dictator. By law, Augustus held a collection of powers granted to him for life by the Senate, including supreme military command, and those of tribune and censor. It took several years for Augustus to develop the framework within which a formally republican state could be led under his rule. He rejected monarchial titles, and instead called himself Princeps Civitatis (“First Citizen”). The resulting constitutional framework became known as the Principate, the first phase of the Roman Empire.


Q3.How was the reign of Augustus by 27 BC? Discuss.
ANSWER:
The reign of Augustus initiated an era of relative peace known as the Pax Romana (The Roman Peace). Despite continuous wars or imperial expansion on the empire’s frontiers and one year-long civil war over the imperial succession, the Roman world was largely free from large-scale conflict for more than two centuries. Augustus dramatically enlarged the empire, annexing Egypt, Dalmatia, Pannonia, Noricum, and Raetia, expanded possessions in Africa and Germania, and completed the conquest of Hispania.

Beyond the frontiers, he secured the empire with a buffer region of client states, and made peace with the Parthian empire through diplomacy. He reformed the Roman system of taxation, developed networks of roads with an official courier system, established a standing army, and also the Praetorian Guard, created official police and fire-fighting services for Rome, and rebuilt much of the city during his reign.

Augustus died in 14 AD at the age of 75. He might have died from natural causes. He was succeeded as emperor by his adopted son (also steps on and former son-in-law), Tiberius.


Q4.Explain the system of administration governed by politicians of senatorial rank in Rome.
ANSWER:
In ancient Rome, provinces were generally governed by politicians of senatorial rank, usually former consuls. A later exception was the province of Egypt, incorporated by Augustus. After the death of Cleopatra it was ruled by a governor of equestrian rank only, perhaps as a discouragement to senatorial ambition as Egypt was considered Augustus’s personal property, following the tradition of earlier, hellenistic kings.

The territory of people who were defeated in war might be brought under various forms of treaty, in some cases entailing complete subjection. The formal annexation of a territory created a “province” in the modern sense of an administrative unit that was geographically defined. Republican provinces were administered in one-year term by the consuls and praetors who had held office the previous year.

Rome started expanding beyond Italy during the First Punic War. The first permanent provinces to be annexed were Sicily in 241 BC and Sardinia in 237 BC. Military expansionism kept increasing the number of these administrative provinces, until there were no longer enough qualified individuals to fill the posts.
The terms of provincial governors often had to be extended for multiple years, and on occasion the Senate awarded imperium even to private citizens, most notably Pompey The Great. Prorogation undermined the republican constitutional principle of annual elected magistracies, and the amassing of disproportionate wealth and military power by a few men through their provincial commands was a major factor in the transition from a republic to imperial autocracy.


Q5.What was the policy of education in the Roman empire?
ANSWER:
Education in the Roman empire contributed to the social mobility that characterized the earlier period of Imperial history known as the Principate.

Education was available only for those who could pay for it, since there was no state- supported system of schools with public funding.

A higher rate of literacy is indicated among military personnel than among the general population. Educated women were not unusual, and there was an expectation that upper-class girls would at least attend primary school, probably in the same classes as boys. Only an elite few, regardless of gender, went on to receive secondary education.

Modest number of slaves were educated and they played a key role in promoting education and the culture of literacy. Teachers, scribes, and secretaries were likely to be slaves. The education of slaves was not discouraged, and slave-children might attend classes with the children of their masters. Book stores were already well-established in Rome by the beginning of the Imperial period, and are found also in urban centers of the provinces.

Books were expensive, but by the later period, popular genres of literature indicated reading for pleasure among non-elites. Emperor sponsored libraries that were to some extent public, and a wealthy individual might donate a library for a community, or accumulate impressive private collections to which in-house scholars might be attached. Literacy is thought to have declined in late antiquity during the transition away from the classical institutions and practices that supported it.


Q6.How was the infrastructure during the Roman empire?
ANSWER:
The infrastructure system in ancient Rome was complex. A system of thirteen Roman aqueducts provided the inhabitants of Rome with water of varying quality, the best being reserved for potable supplies. Water was used in public baths and in latrines. Inferior types of latrine systems have been found in many places, such as house steads, a Roman fort on Hadrian’s Wall in Pompeii, Herculaneum, and elsewhere that flushed waste away with a stream of water. Romans used sea sponges on a stick and dipped in vinegar after defecation.

The Romans had a complex system of sewers covered by stones. They recycled public bath waste water by using it as part of the flow that flushed the latrines. Terracotta piping was used in the plumbing that carried waste water from homes. The Romans were the first to seal pipes in concrete to resist the high water pressures developed in siphons and elsewhere. Beginning around 5th century BC, city officials called aediles supervised the sanitary systems. They were responsible for the efficiency of the drainage and sewage systems, the cleansing and paving of the streets, prevention of foul smells, and general oversight of brothels, taverns, baths, and other water supplies. Roman rubbish was often left to collect in alleys between buildings in the poor districts of the city. It sometimes became so thick that stepping stones were needed.

The empire of Rome, especially the city itself, had a huge demand for water. The average Roman consumed over 200 gallons of water per day. Wealthy households had water supplied to their settlements unlike many poor who could not afford this. Even these people enjoyed the luxuries of Rome’s public baths, fountains, and public toilets equipped with sinks.

River Tiber was the city’s main water source before any aqueducts were constructed. As the population of Rome increased, however, the Romans taste for water became too much for the river to supply.
The paved roads were all constructed so they would require minimal amount of repair and provide a very smooth surface for travelling.


Q7.How was economic scenario of the Roman empire?
ANSWER:
The Roman economy was underdeveloped and underachieved, as subsistence agriculture, urban centers that consumed more than they produced in terms of trade and industry, low status artisans, slowly developing technology, and lack of economic rationality.

Some cities were known for particular industries or commercial activities, and the scale of building in urban areas indicates a significant construction industry. Papyri preserve complex accounting methods that suggest elements of economic rationalism and the Empire was highly monetized. Although the means of communication and transport were limited in antiquity, transportation in the 1st and 2nd centuries expanded greatly, and trade routes connected regional economies.

Economic dynamism opened up one of the avenues of social mobility in the Roman empire. Social advancement was thus not dependent solely on birth, patronage, good luck, or even extraordinary ability. Although aristocratic values permeated traditional elite society, a strong tendency toward plutocracy is indicated by the wealth requirements for census rank. Prestige could be obtained through investing one’s wealth in ways that advertised it appropriately: grand country estates or town houses, durable luxury items such as jewels and silver ware, public entertainments, funerary monuments for family members or co-workers, and religious dedication such as altars. Guilds and corporations provided support for individuals to succeed through networking, sharing sound business practices, and willingness to work.

The new institutions that came into being with the beginning of city life include trade, temple, sea making, sculpture, and the art of writing. All these institutions depend on the initiative of the king.

Q2. What do ancient stories tell us about the civilisation of Mesopotamia?

ANSWER:

Ancient stories of Mesopotamia are valuable sources of information. It is one of the advanced civilization of that time, its society was divided into three classes
(i) Upper classes
(ii)  Middle classes.
(iii)  Lower classes
• People belonging to upper classes live a luxurious life and enjoyed special privileges.
• Agriculture is the main occupation of the people. Their life was normally prosperous.
• Religion was the main part of their life. They worshiped many gods and goddesses.
• Shames was their main god who was the sun. Ziggurat was the name given to the Sumerian temples.

Another description from the bible-
According to bible, the flood was meant to destroy all life on earth. The almighty assigned the task of sustaining the earth, to a man Noah. Noah built a huge boat, and ark and took a pair of each known species of animals and birds on the ark. Thus when every other things were destroyed by the flood, this ark remained safe along with pairs of all species. Thus began a new life on earth.
There is a reference to a strikingly similar story in Mesopotamian tradition, where the principal character instead of Noah , was called Ziusudra or Utnapishtim.


Q3.Why Mesopotamia is considered important by Europeans? Give reasons. (VBQ)

ANSWER:
Europeans considered Mesopotamian important on account of the following reasons:

  • In Old Testament, there are references about it, which refer to ‘Shimar’, meaning the Sumer (the land of brick-built cities). It clearly refers to Mesopotamia, because early planned cities existed there.
  • European scholars and travelers referred to Mesopotamia as their ancestral land.
  • Archaeological discoveries also depict that Europeans had a keen interest in this region.


Q4.“Rivers play crucial role in the emergence of civilization”. Justify this statement in context to Mesopotamia. (HOTS)
ANSWER:
Mesopotamia is situated between the land of two rivers, i.e. Euphrates and Tigris. Both these rivers originated from Armenia mountain in present-day Turkey. They drained a vast mountain region. Although the climate of this area is dry yet agriculture is possible because of irrigation facilities. The favorable agricultural condition encouraged the people to reside in this region. The surplus food production of crops enabled the agriculturist communities to feed those people such as craftsmen, priests, rulers, soldiers, etc. who were not practicing agriculture. The nomadic pastoralist communities provided with other essential needs of daily use to these people. Thus the settlement of all these in this region paved the way for the rise of civilization.


Q5.Give some facts to show geographical diversities that existed in Iraq.
ANSWER:
Geographical diversity existed in Iraq. Some of these arguments that support it are the following:

  • North-east region is lush green region. It is also covered with mountain ranges with clear streams.
  • There is plentiful rainfall in the region which is sufficient for growing crops.
  • In Northern region there is a vast track of upland, called steppe. In this region, animal herders reside who provides better livelihood than agriculture.
  • In the east, River Tigris and its tributaries flows which provides routes of communication into the mountain region of Iran.


Q6.Write in brief about the importance of southern and north-east regions of Mesopotamia.
ANSWER:
Mesopotamian southern region is desert, but the rivers Euphrates and Tigris support the city life here. These rivers deposit their silt by flooding in the region and make the soil fertile. When the river Euphrates enters the desert, it gets divided into small channels. These river channels provided irrigation facilities in the past. Crops such as wheat, barley, peas or lentils were grown here, though there did not happen sufficient rainfall. In the north-east region, sheepary goats were grazed on steppe by the Mesopotamia’s. In this region milk, wool and meat was produced in bulk. Fish was also available in plenty. Date-palm provided fruit in summer. Considering these facts we can conclude that these regions were of utmost importance for Mesopotamia’s.


“Q7.The use of seals played significant role in the development of trade in urbanization in Mesopotamia.” Discuss.
ANSWER:
A number of seals have been excavated from Mesopotamia. These were made of stone and were cylindrical in shape. These seals were fitted with a stick and then rolled over wet clay so that a continuous picture got engraved over it. This work was done by skilled craftsmen. The name of the owner, his God, his official, ranks, etc. were also engraved on it. Seals were used by merchants to send their goods from one place to another. Goods were first packed and a seal was put at the head of the pack to ensure its authenticity. In case seals were found tampered with, it meant the back had been pilfered on the way otherwise it was safe and secure. Undoubtedly, we can say that the use of seals played a significant role in the growth of urbanization.


Q8.“The Euphrates river of ancient Mesopotamia was world-renowned trade route”. How will you justify it? (HOTS)
ANSWER:
Earlier the task of transportation of goods, food grains and other essential commodities were carried by the beasts of burden or bullock-carts. It was a time-consuming activity and a lengthy process. The river Euphrates helped the people to get rid of this task. It flows almost through the entire region of Mesopotamia. It provided people one of the cheapest means of transport, which made possible to transport bulk goods with any difficulty. The boats guided by the direction of winds were available free of cost. Several stream emerging of it provided an excellent source of water transportation. Most of the trade began to carry out on this route. Hence, we can say that the river of Euphrates was a well-renowned trade-route.


Q9.Explain with the help of an example, how did compulsory labor make possible the construction of temples, palaces, buildings, etc.
ANSWER:
Mesopotamian king enjoyed the supreme status in the society and also enjoyed extensive power. The king made labor compulsory to all inhabiting in his empire for rendering their services to town’s deities and to construct temples. For example, the construction of temple in Uruk city was done by 1500 people working 10 hours a day. This work continued for five years. No person could seek immunity from compulsory labor. The people who were engaged in compulsory labor were paid grains in lieu of their services.


Q10.How pictographic script came into prominence?
ANSWER:
The trace of written language has come up from Sumer in Mesopotamia. They are dated back to 3200 BCE. It is believed that the written language was evoked by temple priests, who were assigned to look after temples independently by the king. They had to keep the records of the expenditure and income of the temples. So they began to paint the items donated to the temples on clay tablet. In this, they began to keep these records. The temple of Uruk has revealed a list of 5000 such tablets. They engraved the pictures like signs and numbers of oxen, fish, etc. Now, it became easier to remember the things. In this way, the pictographic script came into prominence.


Q11.What do you know about the ancient town Ur of Mesopotamia?
ANSWER:

  • This city was founded by Mesapnanda about 2670 BCE. It was a well-known commercial centre and a port was destroyed by Elemites around 2200 BCE.
  • Ur was re-established under Ur-Nammu in 2100 BCE.
  • It was first excavated by British excavator J.E. Taylor in 1854-55.
  • This city was designed without planning as the excavation depicted.
  • Excavation was carried out on a large scale during 1920’s and 1930’s, under the supervision of Sir Leonard Woollsey.


Q12.Which factors suggest that Ur was an unplanned city?
ANSWER:
Ur was an unplanned city because excavation here reveals that people used to throw domestic garbage in the street. As a result of this, the level of the streets began to increase. Holders had to raise the level of their house for proper arrangement of light inside their rooms. It was made possible through doors, rather than windows. Several superstitious beliefs were also prevalent among Ur people regarding their houses under consideration. For example, they raised threshold of a house that brought prosperity. They believed that the first door that did not open towards another house was good and praiseworthy. In case, the door opened outward, it is believed that their strained relations between the husband and the wife residing in it.

Q1.What do you know about Uruk?
ANSWER:
Situated on the bank of the river Euphrates, about 2500 kilometers south-east of modern capital city of Baghdad, Uruk is an ancient Mesopotamian city. It came into existence around 3000 BCE, and was reckoned to be the most extensive town in the contemporary world. Uruk spread over an area of 250 hectares. It was twice in size when compared to Indus valley civilization. The city expanded around 2800 BCE. This area increased to about 400 hectares. Nearly 50,000 to 80,000 people resided here at that time.

Sumerian king Ermerkar was the founder of this town. He also constructed here the temple of a well-known goddess Inanna. Another famous ruler of this town was Gilgamesh. He declared Uruk as the capital city of his empire. To safeguard ground from any invasion he constructed a massive town around it. Here in Uruk the war prisoner had to do compulsory labour either for the ruler or for construction of temple. They were paid in grains in return. The common people were engaged in the extraction of stones, making mud-bricks, etc. as per the order of their ruler.

Uruk had also made unprecedented progress in the field of technology. The invention of potter’s wheel led to a revolutionary change in the field of technology and also helped in utensil making on a large scale.


Q2.Describe the main features of the city of Babylon.

Q3.Describe the nature of early urban society under Mesopotamia.
Or
“There was a great disparity among the different sections of the Mesopotamian society”. Explain.

ANSWER:
The early urban society was divided into three classes. The first class or group of the people coming from elites and consisted of the king (Monarch), the priest, the officials, rich merchants and businessmen, high military officials, etc. They led a luxurious life and lived in magnificent buildings and palaces. They wore expensive clothes and used to eat sumptuous foods. The people of this class were served by several men and women slaves. The people belonging to second class consisted of the people such as small scale merchants, artisans, state officials, intellectuals, etc. Like upper or 1st class they also led a life of luxury. The third estate or class people constituted the lowest strata of the society. Their life was very miserable. The dead bodies of the upper class people were buried along with precious items such as gold vessels, oyster shell, lapis lazuli, etc. On the other hand, the dead bodies of common people were buried along with ordinary pots, etc. It clearly indicates that there was great disparity among the different sections of society.

Q4.Illustrate the construction of temple and gradual increasing of activities of temples in Mesopotamia.
ANSWER:
Mesopotamian temples have played a significant role in the history of Mesopotamia. They constructed temples and dedicated them to their different gods and goddesses. Their temples were dedicated to Nanna, Anu, Enki and Inanna. Besides these four deities, each town had its own deity who was considered to be the protector of the respective town.

Temples of early Mesopotamia were comparatively smaller in size. They were also made of unbaked bricks. With the passage of time, the temple began to take new shape. Their importance as well as size began to increase. They used to build their temples on the hill tops because they believed that God (deities) dwell on the hill-top. These temples were made of baked bricks.

One of the peculiar features of these temples was that their outer walls had inward and outward bend at regular intervals. The temple had a courtyard and there were several rooms around it. The image of the deity was placed in the main room. Some rooms served as dwelling places for priests and other rooms were meant to stay for the pilgrims.

  • Temples were also engaged in sales and purchases of goods and also used to provide advance loans to the traders and charge interest thereon.
  • The people offered grains, curd, dates, etc. to serve their deities. They also sacrificed ox, sheep, goat, etc. to offer their blessings.
  • Temples also served as the centers for entertainment and provided a common platform for the people to meet each other and get a new boost.


Q5.What do you know about Gilgamesh? Explain in detail.
ANSWER:
The Gilgamesh epic occupies a special place not only in Sumerian literature, but also in world history. It was written by Uruk ruler Gilgamesh, who ruled there about 2700 BCE. It was written on 12 tablets. This epic is about the achievements of Gilgamesh. Gilgamesh was a famous ruler of Uruk. He was a great ruler and laid the foundation of a vast empire. To secure the Uruk against any threat of the foreign ruler he constructed a well around it with a view to end his tyrannical rule. People prayed to deity, Anu. As a result of this, God Anu ordered the goddess Arur to create such a God who could surpass Gilgamesh. The goddess created Enkidu who fought with Gilgamesh. He was impressed by his bravery and became a fast friend.

“They both performed several commendable works and decided to kill a demon of Elam known as Humbaba. After a terrible war, Gilgamesh finally killed Humbaba. Impressed by the bravery of Gilgamesh, Ishtar fell in love with her.

Gilgamesh’s friend Enkidu fell in love with a beautiful dancing girl. This enraged the deities. So they decided to end the life of Enkidu. Soon after he fell ill and died. The death of Enkidu deeply hurt Gilgamesh. He began to think one day that he will also die. Thus he began his search to attain immortality, but no one could ever become immortal. At the time of creation of a human being God gave him (the man) death and kept life with them. Despite this he did his best to become immortal.

Finally, he thought about Utnapishtim. Being impressed by his efforts Utnapishtim revealed the secret of immortality through the pant lying at the button of an ocean (sea). Gilgamesh accepted this challenge and jumped into the sea to bring the said plant. On his return he was very tired and fell asleep. Meanwhile a snake came here and took away that plant. When he woke up he saw the desired plant was missing. Finally, he understood the fact that the man can never become immortal. He came back to his native city. After many years he became emotional on seeing his city. He realised the fact that hi. sons will continue to enjoy the vast empire built by him after his death.

Short Answer Type Question:

Q1.Discuss the extent to which (a) hunting and (b) constructing shelters would have been facilitated by the use of language. What other modes of communication could have been used for these activities?

ANSWER:

  • Hunting and constructing shelters would have been facilitated by the use of language because these two activities are group activities requiring collective labour and cooperation among fellow humans.
  • Humans certainly had to communicate with each other during the group activities. Language was vital tool in these group activities.

Other modes of communication:

  • Gestures or hand movements, other non-verbal communication such as singing or humming, imitation of movements and sounds of birds and animals, cave paintings and other expressions with signs could have been used for these activities.

Q2.Choose any two developments each from Timelines 1 and 2 at the end of the chapter and indicate why you think these are significant.

ANSWER:  Timeline- 1

2.6-2.5 mya – Earliest stone tools

The earliest evidence for the making and use of stone tools comes from sites in Ethiopia and Kenya. It is likely that the earliest stone tool makers were the Australopithecus. Tools enabled man to become hunter from scavenger, and then, cultivator of his own crops for food.

0.8 mya- ‘Archaic’ sapiens,Homo heidelbergensis

The earliest fossiIs from Europe are of Homo heidelbergensis and Homo neanderthalensis. Both belong to the species of archaic (old) Homo sapiens. The fossils of Homo heidelbergensis (0.8-0.1 mya) have a wide distribution, having been found in Africa, Asia and Europe.

Timeline- 2

Development of voice box -200,000 years ago

The brain of Homo habilis (the tool maker) had certain features which would have made it possible for them to speak. Thus, language may have developed as early as 2 mya. The evolution of the vocal tract was equally important. This occurred around 200,000 years ago. It is more specifically associated with modern humans.

Invention of sewing needles- 21,000 years ago

The trapping of fur-bearing animals (to use the fur for clothing) and the invention of sewing needles are important developments in human history. Early man had used grass, leaves, tree bark, and animal skin to protect his body from harsh weather. The invention of sewing needles made it possible to stitch cloth and make many strong and durable dress materials. Man started experimenting with various types of naturally available fibrous materials such as silk, cotton, wool, jute. This revolutionized his material condition and culture. The earliest evidence of sewn clothing comes from about 21,000 years ago.
Q3/What do you know about Java men? Why did scientists call them “The Erect Ape Men”?
ANSWER: The remains of Java men were first discovered by a Dutch surgeon in Java. It included-a skull, a thigh bone and two teeth. The study of these remains depicts that the Java was half ape and half man. It is because his head (Java man’s head) was set forward of the neck. The Java men were also called “The Erect Ape Men” by the scientists because they could walk erect.
Q4.How did the use of language prove valuable in the construction of shelters?
ANSWER:
The use of language proved helpful in the construction of shelters in following ways:

  • People could now secure places about their settlement.
  • They became aware about resources available in near surroundings.
  • They could discuss the ways of pattern of constructing their shelters.
  • They could consider the ways and means to protect their shelters from predators and severe storms..


Q5.What do you know about cave paintings at Altamira?
ANSWER: Altamira is a cave site in Spain. The paintings on the ceiling of the caves were first brought into notice of an amateur archaeologist Marcelino sanz de Sautuola and his daughter Maria in November 1879. Maria suddenly noticed the paintings on ceiling when his father was busy in digging the floor of the cave. She brought these paintings to the notice of his father. At first looking of the picture of oxen, he just laughed, but soon he realised that some sort of paste rather than the paint has been used for painting. Two decades later, his findings were dismissed by European archaeologists on the ground that they did not appear too good to be very old.


Q6.Explain the effects of changing environment around 12,000 years ago.
ANSWER: Around 12,000 years ago, there was a change in the climate of the world. There was an increase in the temperature of their environment. It resulted into the development of grasslands in many regions which in turn led to an increase in the number of animals that ate grass like deer, antelope, goat, sheep, cattle, etc


Q7.Where do we get the earliest evidence of planned hunting? What did it depict?
ANSWER: We get the earliest evidence of planned hunting from European site Dolni Vestonice, Czech Republic. This site is nearby a river and it is believed that it was deliberately used by people. During the autumn and spring seasons reindeer and horse crossed the river and killed or hunted by early human on a large scale. The selection of such site depicted that the people were well aware about the movement of birds and animals and able to kill (hunt) them in large numbers.

Q1.Write a description about the origin of human beings.
ANSWER:
The story about the origin of human beings is very long and complicated. Different views in this regard have been given, and still the process of discoveries is going on. The chronological order of the number of events has changed due to new discoveries and excavations made so far. There is plenty of scope left for excavations. The early human passed through several stages of journey to become a modern man. The various stages which throw light on the story of progress made by man from the very beginning to the present days are given below.

  • Primates: The early human came into being in Africa and Asia about 36-24 mya. They constitute a sub-group of a large group of mammals, such as monkeys, apes, and the humans. They had hair on their bodies and different kinds of teeth.
  •  Hominoids: They came into being about 24 mya. They had four legs and used to move on their four paws. The first portion of their bodies and legs were quite flexible but were unable to walk erect. Their
  • body was different from the monkeys because they were comparatively larger and had no tail.
  • Hominids: They belonged to hominidae family and came into existence about 5.6 • mya. Their earliest fossils were excavated at Laotoli and Hader (both in Africa). It is a clear evidence that they originated in Africa. Their fossils were also found outside Africa.


Q2.What do you know about early man’s tools and weapons made by them? Which techniques were used to make these tools?
ANSWER:
Early man’s tools and weapons were made of stones. Early man used hard stones known as flint, along with other types of stones for making tools and weapons. Flint was the stone that was used for lighting fire. It was also found that these types of stones can be given desired shape. However, the tools that early man

used were rough and unpolished. We get the earliest evidence for making and use of these stone tools from Ethiopia and Kenya. The Australopithecus were the first to make and use stone tools.
The stone tools were made by using following techniques:

  • Stone on Stone: In this technique, the pebble from which the tool was to be made was held in one hand and the second stone was used to strike off flakes from the first.
  •  Pressure Flaking: In this technique, the core was placed on a firm surface. The hammer stone was used on a place of bone or stone that was placed on the core to remove flakes that could be shaped into tools.
  • The Punch Blade Technique: In this technique, the top of a larger pebble is removed by using hammer stone to produce a flat surface. This flat surface, thus so produced, is called striking platform. This is then struck using a hammer and a punch made of bone. It then leads to the production of blades. It also leads to formation of knives.

Q3.Undoubtedly the modern man-made tremendous progress since coming into being.” Justify the statement. (HOTS)
ANSWER:
Modern man had several peculiarities which made him different from his predecessors. Modern man is most intelligent in comparison to forefathers on account of the size of his brain. Modern man-made tremendous progress. He began to construct his huts in addition to the caves wherein he dwelled earlier. He started to lead a settled life and began practicing agriculture. Now, he does not wander here and there in search of his food. He acquired knowledge how to cook food and also learnt how to store food grains and consumed it properly. He began to store food grains for his future use or used it when required during the time of natural calamity. He also used much superior tools, which helped him to safeguard himself from the wild predatory more effectively. The invention of needle helped him to wear stitched clothes. The development in the field of art and language made him more superior. So we can conclude that the modern man made great achievements in comparison to his forefathers.


Q4.Discuss in detail about the places of residence of early humans.
ANSWER:

  • The early humans lived on the branches of the trees. Between 400,000 and 125,000 years ago, the human beings began to live in caves and open air sites.
  • We got the earliest evidence of living in caves from Lazaret cave in southern France. It measured 12 x 4 meters and revealed evidence of two hearths, several fruits, vegetables, seeds, nuts, eggs of animals and fishes.
  • Dwelling in caves proved beneficial for him, as he could now protect himself from the danger of wild animals. Living in caves provided him natural refuge from severe stream and cold.
  • The early humans began to live or dwell in huts around 125,000 years ago. It proved a significant step in early human’s journey towards progress.
  • We get the most significant evidence of the hut constructed by early humans at Terra Amata in Southern France. It was made up of thatch and its roof was made up of wood Reconstruction of hut at Terra Amata stone-flakes scattered on the floor.

Q5.Who were the first to use tools? How these tools used by early man were categorized?
ANSWER:
Australopithecus were the first to use tools. About 35,000 years ago, we came across the evidence of a remarkable improvement in the method of hunting animals. It became clear from the event that a special type of spear was used to hunt animals.
The tools used by early man can be categorized into three types. They are discussed under following heads:

  • Hand-axes: They were used for pouncing. In the beginning, they were used without a handle, but later on wooden handle was attached to it. It was made possible to use them with much force.
  • Chopper: They were made of heavy stones worked to a sharp edge in one direction only, and were most probably used for chopping meat.
  • Flake implements: They were used as knives and scrapers for finer works. For thousands of years of man’s early history the only remains that we find are crude stone tools. These tools are often found lying along the terraces of rivers, or in the huts or caves where early man used to live and roam in search of wild animals. These tools made by him served many purposes such as skimming of dead animals, cutting their flesh, etc.
    About 35,000 years ago new kinds of tools such as spear throwers, bow and arrow came into being.

Q7.How did early man procure his food? Explain.
ANSWER:
The early man procured his food through a number of ways. Some of the ways are listed below:

Gathering: For his food items, early man was totally dependent on nature. He was a pastoralist nomad, who kept on wandering. In the very beginning, he was a food-gatherer. He gathered eatables from trees and plants. The main food items were seeds, nut, fruit, etc. All these food items could be preserved. There is lack of evidence. The prominent role in food-gathering was played by women and children.

Scavenging: The early man also procured his food through scavenging. They used to obtain food from the carcasses of those animals which had died naturally or had been killed by other larger animals. They were used to eat the meat of small birds, eggs and several kinds of insects.

Hunting: To procure food through hunting was also one of the best methods of obtaining food. Hunting was mainly the domain of menfolk. They used to hunt the small animals individually, but in case of the hunting of large animals, group efforts were the key to success. They hunted wild animals such as wild horses, wild buffaloes, rhinoceros, bear, etc. They used spears and tools made of stone to hunt wild animals. We get the earliest evidences of well planned hunting and butchery of large animals from Boxgrove in Southern England and Schoningen in Germany. About 35,000 years ago, there is some evidence of planned hunting that comes from European sites. One such site of planned hunting is Dolini Vestonice in Czech Republic. This site was situated in close proximity to a river, where a number of animals came to drink water. Horses and reindeers were used to come here to drink and cross the river during autumn and spring migrations. Then they were hunted on large scale, by the early humans who were well aware about their movement.

Fishing: Early man also obtained his food by fishing. They caught fish from rivers and ponds with their hands. Later on hooks and harpoons for catching fishes came into use.


Q8.Discuss the progress made by early man in the field of art.
ANSWER:

The early man was much interested in the field of art. He found that art is a unique
method to express his feelings. So, he tried his hands both in paintings and sculptures.

(i) Paintings: In the very beginning, the early man tried to express every thing which impressed him in his daily life. He was much impressed by seeing (observing) natural beauty, i.e. flora and fauna, the sun, the moon, stars, rivers, etc. and also fond of hunting. Hunting was the part of his daily routine. So he painted many pictures depicting the hunting theme. The paintings depicting hunting theme have been envisaged on the wall of the caves and ceiling on the walls. For example, the caves of Altamira, Lascaux, and Chauvet are specially well known. Altamira caves were discovered by Marcelino sanz de Sautuola and his daughter in 1879.

  • Lascaux and Chauvet caves came into limelight in 1894. These caves have plenty of beautiful pictures.
  • Most of these paintings are of horses, bison’s, mammoths, bears, leopards, owls, etc. Black, red, yellow and white colors have been widely used for engraving these paintings. A number of questions have been put forward regarding the above mentioned paintings.
  • Scholars have different opinions in this regard. Some scholars are of the view that they painted these pictures to beautify the walls and ceilings on the caves while others put forward their argument as they did so to pass their knowledge from one generation to another.

(ii) Sculpture: Small-sized statues were built by early man, representing humans and animals. Most of the human statues were of women and recovered from several places in Europe. These female statues are called Venus goddes
