In-Text Questions
Every “Let’s Explore” and “Think About It” box, in the order they appear through the chapter.
1What is the earliest memory you can recollect? Do you remember how old you were at that time?
This is a personal reflection — everyone’s answer will differ. A good way to work it out: recall a vivid moment (a birthday, first day at school, a family trip), then subtract your birth year from the year that event happened to find your age at the time. Most people’s earliest memories go back to around five or six years of age, exactly as the chapter suggests.
2How do you think understanding the past will help us understand the present world?
Understanding the past helps us in several ways:
- It explains why things are the way they are today — our customs, institutions, languages and technologies all have roots in the past.
- It lets us spot patterns and causes — why conflicts, migrations, or inventions happened — so we can learn from past successes and mistakes.
- It gives us a sense of identity — of our family, community and nation.
- It helps us make more informed decisions for the future, by recognising situations that have occurred before.
1Draw a simple timeline marking every year from 2 BCE to 2 CE. Show that only 3 years have passed between those two dates.
Because the Gregorian calendar has no ‘year zero’, the year 1 CE follows immediately after 1 BCE:
Even though there are 2 years marked on each side, only 3 gaps (3 years) separate 2 BCE from 2 CE — not 4.
2How do you calculate the number of years between a BCE date and a CE date?
Add the two numbers, then subtract 1 (to correct for the missing year zero):
Check against the timeline above: ✓ matches the 3 years we counted.
3Worked example: The Buddha was born around 560 BCE. If we are now in 2024 CE, how many years ago was that?
Extra practice: Ashoka became emperor around 268 BCE. How many years ago was that (from 2024 CE)?
Ashoka’s accession was 2,291 years agoIn the timeline on pages 62–63 (Fig. 4.3), can you mark the beginning of the 8th millennium BCE?
Millenniums BCE are counted backward starting from 1 BCE, so the 1st millennium BCE = 1 BCE to 1000 BCE, the 2nd = 1001 to 2000 BCE, and so on. This makes the 8th millennium BCE run from 7001 BCE to 8000 BCE.
Its beginning (its earliest, furthest-back year) therefore falls exactly at the 8000 BCE mark already labelled on the timeline — the point directly between the “10,000 BCE” and “6000 BCE” marks in Fig. 4.3.
Create a timeline stretching from 1900 CE to the current year and place the dates of birth of your grandparents, parents, siblings and yourself. Also mark the years the 20th century CE begins and ends with.
Since centuries are counted in blocks of 100 starting from year 1 CE, the 20th century CE runs from:
1901 CE → 2000 CE
For your personal timeline, draw a horizontal line from 1900 CE to today, mark it in decades (1900, 1910, 1920 … ), and place a dot for each birth year — for example:
| Family member | Example birth year | Falls in which century? |
|---|---|---|
| Grandparent | 1958 | 20th century CE (1901–2000) |
| Parent | 1985 | 20th century CE (1901–2000) |
| You | 2014 | 21st century CE (2001–2100) |
(Replace these example years with your own family’s actual birth years — this activity is personal to your household.)
Collect information about at least three generations of your family. Create a family tree with names, occupations, place of birth, and your source of information for each.
This is a personal research activity, so there’s no single fixed answer — but here is a worked example of one filled-in row to show the kind of detail expected:
| Relation | Name | Occupation | Place of birth | Source of information |
|---|---|---|---|---|
| Grandparent (paternal) | e.g. Ram Lal Sharma | Farmer | Alwar, Rajasthan | Told by father; confirmed from old ration card |
| Grandparent (maternal) | — | — | — | — |
| Great-grandparent (paternal) | — | — | — | — |
| Great-grandparent (maternal) | — | — | — | — |
Fill in the blank rows with your own family’s details. Typical sources of information include: conversations with parents/grandparents, old photographs, diaries, ID cards (ration cards, voter IDs), school certificates, land records, or family religious/genealogical records (like a pañji or priest’s register).
Have you ever seen old coins, books, clothes, jewellery or utensils in and around your house? What type of information can we gain from such objects? Or from old houses or buildings?
Tell us about the ruler or kingdom that issued them, the economy and trade of that time, and the script/language in use.
Reveal levels of literacy, how language has changed over time, the ideas and beliefs people held, and the printing/writing technology available.
Show us the fashion, textile technology, social or economic status of the wearer, and how people adapted clothing to their climate and occupation.
Reflects craftsmanship and metalworking skill, available materials, social status, and sometimes trade links (if the gems or metals were imported).
Tell us about cooking practices, diet, family size, and the metallurgy or pottery technology of the period.
Show us architectural style, building materials and construction technology, social organisation, and sometimes religious or cultural practices of the people who built them.
There are a few images of different sources of history on the next page. Who and what do you think the objects show? Write down any information you get from these objects.
An ancient gold coin showing a seated royal figure with an inscription running around the rim — coins of this style were minted by early Indian dynasties (such as the Gupta rulers). A coin like this is a form of inscription source: it tells us about the ruling king, the economy and currency system, the script/language of the period, and sometimes the religious symbols favoured by the ruler.
A stone relief panel showing several human figures under pillared canopies, along with a boat scene below — the kind of carving found on temple walls. This is an artistic source: it tells us about religious or mythological stories, clothing and ornaments of the time, and the sculptural skill of the craftsmen.
This is the famous Lion Capital of Ashoka (originally atop a pillar at Sarnath) — four lions standing back to back on a drum carved with a wheel (chakra) and animals. It is a structure/monument source: it tells us about Mauryan-era stonework, Emperor Ashoka’s patronage of Buddhism, and its symbolism is important enough that independent India adopted it as the National Emblem.
Look at the picture of early humans in a rock shelter. Which activities can you recognise? Give a brief description for each.
- Rock/cave painting — a figure is shown reaching up to paint animals and human-like figures on the rock wall, while a child watches, perhaps learning the skill.
- Making and tending fire — a group sits around a fire, which was used for warmth, protection from animals, and cooking.
- Preparing food/hide — people are seen working on an animal skin spread on the ground, likely scraping or stretching it for use.
- Grinding food — a person is grinding something in a large stone container, an early form of food processing.
- Group/family living — people of different ages (elders, adults, children) sit together, showing that early humans lived in bands or groups for mutual support.
- Wearing simple ornaments — a figure appears to be wearing a necklace, showing early personal adornment.
In the rock shelter and farming-village pictures, men and women are shown doing certain tasks. Are these roles necessarily accurate for all early humans? Discuss.
- The roles shown in these illustrations are simplified for teaching purposes — they are not proof that early human societies always divided work strictly by gender.
- Because our evidence about the deep past is limited (mainly indirect clues from bones, tools and paintings), historians and archaeologists cannot always be certain exactly who did which task.
- It is quite possible that, for example, women also painted on cave walls or hunted at times, and men helped with cooking or looking after children — tasks were likely shared more flexibly than the pictures suggest.
- The key lesson is to avoid assuming that today’s gender roles or stereotypes automatically applied to people who lived tens of thousands of years ago.
Observe the scene of an agricultural community from a few millenniums ago. List the main activities you can identify.
- Harvesting crops — people are cutting and gathering grain (wheat/barley) by hand in the field.
- Carrying the harvest — bundles of cut crop are being carried on the head back towards the settlement.
- Herding animals — a flock of sheep/goats is being grazed and tended, showing domestication of animals.
- Carrying tools — a man carries a stone axe/tool over his shoulder, on his way to work.
- Building/repairing huts — a figure is shown working on the wall of a thatched-roof hut, showing settled housing.
- Cooking — a woman is preparing food over an open hearth outside a hut, with vegetables laid out nearby.
- Children at play — children are shown near the huts, indicating settled family life.
- Settlement near a river — the huts are built close to a water body, for water supply and fertile soil — exactly as the chapter describes.
Exercise Questions
“Questions, activities and projects” — page 74 of the chapter.
As a project, write the history of your family (or village if you live in one), using sources of history at your disposal. Ask your teacher to guide you.
- Interview elders in your family/village — grandparents, parents, or long-time residents — and note down what they remember.
- Collect documents and objects — old photographs, certificates, land records, letters, ID cards, or heirlooms.
- List key events with approximate dates — births, migrations, marriages, occupations, or important village events (a new well dug, a school built, etc.).
- Organise everything chronologically into a short written account or a timeline, just like Fig. 4.3 in the chapter.
- Record your source for every fact — e.g. “told by grandmother,” “seen in old photograph,” “read on gravestone” — the same way historians cite their sources.
Can we compare historians to detectives? Give reasons for your answer.
Yes, historians can reasonably be compared to detectives. Reasons:
- Both start with incomplete evidence — a detective has clues at a crime scene; a historian has surviving sources like coins, inscriptions or ruins.
- Both must cross-check different pieces of evidence against each other — just as the chapter describes, sometimes the “jigsaw pieces” (sources) match, and sometimes they contradict each other, requiring the historian (like a detective) to judge which source to trust more.
- Both build a coherent explanation of what happened from indirect evidence, without having witnessed the event themselves.
- Both must stay objective and revise their conclusions if new evidence turns up later.
One difference: a detective usually investigates a single recent event, while a historian often reconstructs events from centuries or millennia ago, where direct witnesses can never be questioned.
aPlace these dates chronologically on the timeline: 323 CE, 323 BCE, 100 CE, 100 BCE, 1900 BCE, 1090 CE, 2024 CE.
Remember: for BCE dates, the larger the number, the further back in time (earlier) it is. For CE dates, the larger the number, the more recent. So, from earliest to latest:
BCE
BCE
BCE
CE
CE
CE
CE
1900 BCE → 323 BCE → 100 BCE → 100 CE → 323 CE → 1090 CE → 2024 CE
bIf King Chandragupta was born in 320 CE, which century did he belong to? And how many years was that after the Buddha’s birth?
cRani of Jhansi was born in 1828. Which century did she belong to? How many years was that before India’s Independence?
dTurn ‘12,000 years ago’ into a date.
(If you use today’s actual year instead of 2024, the answer shifts by only a couple of years — negligible over a 12,000-year span.)
Plan a visit to a nearby museum: research its exhibits beforehand, keep notes during the visit, and write a brief report afterwards.
- Before the visit: Look up the museum online or ask your teacher what kind of exhibits it holds (archaeological finds, art, coins, natural history, etc.), so you know what to look out for.
- During the visit: Carry a small notebook. Note down the names, approximate age, and origin of at least 4–5 exhibits that interest you, and sketch or photograph (where allowed) anything striking.
- After the visit: Write a short report covering: what you saw, what surprised you, what you found most interesting or fun, and one new thing you learned about history from the visit.
Invite an archaeologist or historian to your school and ask them to speak on the history of your region and why it’s important to know it.
- Work with your teacher to identify and contact a local historian, archaeologist, or museum curator (colleges, local heritage societies, or the state Archaeology Department are good places to ask).
- Prepare a short list of questions in advance — for example: “What historical sites exist near our region?”, “What sources tell us about our region’s past?”, “Why should young people care about local history?”
- During the talk, take notes and ask follow-up questions.
- Afterwards, discuss as a class what you learned, and how it connects to the chapter’s ideas about timelines and sources of history.
