NCERT Class 6 Social Science Chapter 4 MCQs – Timeline and Sources of History

History is the study of the human past. It helps us understand how people lived and how societies changed. Learning about earlier experiences also helps us make better sense of the world we live in today.

Palaeontologists study ancient remains preserved as fossils. These may include parts or impressions of plants and animals within rocks or soil. Their work helps us learn about forms of life that existed long ago.

Anthropologists study human societies and their cultures, from ancient times to the present. Their work contributes to understanding people’s ways of life. It helps historians place human activities and traditions in a wider context.

Archaeologists investigate the past by excavating and studying material remains. Tools, pottery, beads, bones and parts of buildings can all provide clues. These remains help us understand people who lived before our own time.

An era is a distinct period of time. Societies have sometimes begun eras from major events, such as a ruler’s accession or an important person’s birth. Such starting points help people organise and describe dates.

CE stands for Common Era. It is used with years such as 1947 CE, when India became independent. The chapter explains that CE is now commonly used where the older abbreviation AD was used.

BCE stands for Before Common Era. It refers to years before the starting point of the Common Era. These years are counted backwards, so larger BCE numbers describe dates further in the past.

There is no year zero in the historical date system explained in the chapter. The year 1 BCE is followed immediately by 1 CE. This matters when calculating time intervals that cross between BCE and CE.

A timeline places dates and events in a sequence. It helps us see which event happened earlier and which happened later. Timelines can cover a short period or stretch across thousands of years.

A decade is a period of ten years. Historians use decades along with years, centuries and millenniums to describe time. These different units make it easier to discuss both short and long periods of history.

A century contains one hundred years. Because the first century CE begins with year 1, the 21st century begins in 2001 and ends in 2100. The chapter uses this example to explain century counting.

A millennium is a period of one thousand years. It is useful when discussing very long stretches of history. The chapter explains that the third millennium CE began in 2001 and continues through 3000.

A pañchānga contains tables of days and related astronomical information. It may include sunrise and sunset times, eclipses and festival dates. The chapter mentions it as part of India’s long tradition of making calendars.

Family photographs, diaries, documents and relatives’ memories can provide information about earlier generations. The chapter encourages students to record their sources. Using such evidence helps make a family history clearer and more reliable.

An epigraphist studies ancient inscriptions. These written records may preserve information about rulers, events or other aspects of the past. Their study contributes to the evidence that historians use when reconstructing historical periods.

Different sources may support one another or give conflicting information. Historians compare them carefully and decide which evidence is more trustworthy. This process helps them build a stronger understanding of the period they are studying.

Early hunter-gatherers hunted animals and gathered edible plants and fruits. They often lived in groups that helped one another survive. Finding food and shelter were important tasks in the challenging natural conditions they faced.

Rock paintings may show animals, people, activities and symbols. They provide clues about early human life and expression. However, they do not tell us everything, so they must be understood alongside other available evidence.

Rivers provided water, and nearby soil could be fertile. These conditions made cultivation easier for early communities. As farming and animal domestication increased food supplies, settlements could grow in both size and number.

The chapter describes the use of copper before iron in early technological development. Metal helped people make useful tools, daily objects and ornaments. Pottery and exchanges between settlements were other important developments during this period.

BCE dates are counted backwards from the beginning of the Common Era. A larger BCE number therefore marks an earlier year. Among these choices, 500 BCE lies furthest in the past on a timeline.

To calculate an interval from BCE to CE, add the two year numbers and subtract one because there is no year zero. Here, 5 plus 5 minus 1 gives an interval of nine years.

The 19th century CE runs from 1801 to 1900. Since 1828 falls within this range, it belongs to that century. Century numbers are one higher than the first two digits for most years in the period.

The chapter gives the 3rd century BCE as the years from 300 BCE to 201 BCE. An event in 250 BCE fits within that range. BCE century ranges move backwards towards larger year numbers.

Historical sources sometimes disagree. The chapter explains that historians examine the evidence and judge which source can be trusted more. Comparing additional sources helps them investigate the disagreement instead of choosing a date without reasons.

Everyday objects can carry information about earlier lives. A cooking pot is a material source, just like tools, ornaments or pottery found during excavation. Historians combine these clues with other evidence to understand the past.

The family-history activity asks students to record where their information came from. Adding documents, photographs or relatives’ accounts makes the evidence clear. It also helps others check details and understand how the family tree was prepared.

The chapter cautions that pictures of early life cannot show every possible situation. Men may have cooked or cared for children, and women may have painted. Limited evidence does not justify fixed assumptions about everyone’s roles.

Different excavated remains reveal different parts of earlier life. Grains, bones and pottery can help researchers investigate food, animals and everyday activities. Studying them together gives a fuller picture than relying on one object alone.

Historians and detectives both work with clues that may be incomplete or conflicting. They compare evidence and look for explanations. The chapter’s puzzle example shows why careful investigation is needed to reconstruct events from the past.
