Harappan archaeology

Correct answer: A. After 1900 BCE

Explanation: The governing chronological concept is the transition after the Mature Harappan phase. Evidence from several sites indicates that the decline of many major urban centres began around or after 1900 BCE, although the process was regionally varied and did not mean that all settlements suddenly disappeared. Therefore, option A is correct; the other dates belong to periods far earlier or much later than the Harappan decline.

Correct answer: B. Changes in river courses and environment

Explanation: The governing concept is that historical change usually has multiple possible causes rather than one certain explanation. Shifts in river courses, weakening monsoons, ecological stress, and changing settlement patterns have been discussed as possible factors in Harappan urban decline. Thus, option B is the best answer. The invasion-only claim is too narrow, while modern machines and paper currency are anachronistic.

Correct answer: A. Bricks

Explanation: The governing concept is Harappan building technology. House walls were generally constructed with mud bricks or baked bricks, depending on the location, function, and available resources. Baked bricks were especially important in many urban structures, and standardised proportions are a notable feature. Therefore, option A is correct; grass, metal, and glass were not the normal materials for complete house walls.

Correct answer: B. From public and household wells

Explanation: The distinction between public and household wells reveals that water was obtained through more than one level of urban provision. Public wells could serve neighbourhoods or shared spaces, whereas domestic wells supplied individual houses or smaller groups. Thus option B best demonstrates both systems. Ponds, rivers, and rainfall may have supported water availability, but they do not by themselves prove separate public and private arrangements.

Correct answer: D. Mohenjodaro

Explanation: The Great Bath is one of the best-known structures excavated at Mohenjodaro, where it stood within the raised citadel complex. Its carefully constructed tank, surrounding rooms, and waterproofing show planned public architecture. Therefore option D is correct. Harappa, Lothal, and Dholavira were also important Harappan sites, but the Great Bath is not associated with their citadel areas.

Correct answer: D. On wet clay

Explanation: The governing concept is the archaeological use of seals in identification and control. A seal was pressed into soft, wet clay, which retained the design after the clay dried. This impression could mark a container, package or document and help show its association or security. Therefore option D is correct. A stone wall, dry grain or wooden post would not preserve the impression in this practical way.

Correct answer: D. Clay toy carts

Explanation: Clay toy carts are archaeological evidence of wheeled vehicles in Harappan society. Their form represents carts and suggests that similar vehicles may have been used for transport, potentially drawn by bullocks. Stone pillars, swords and burial pots do not directly depict or indicate wheeled transport. The evidence supports the inference about carts, although it does not prove every detail of their construction. Thus, option D is correct.

Correct answer: D. From bones of domesticated animals

Explanation: The governing concept is archaeological interpretation: animal bones can reveal how people used and managed animals. If excavated bones belong to domesticated cattle, sheep, goats, or related animals, they support the inference of animal husbandry. Drains and bricks mainly reveal sanitation and construction, while seal shapes alone cannot establish herding. Therefore option D is the strongest evidence, although archaeologists compare several kinds of evidence before reaching a conclusion.

Correct answer: A. From differences in house sizes and objects

Explanation: The governing concept is cautious inference from material culture. Archaeologists compare house size, construction quality, location, and the kinds of objects found in different spaces. Larger houses or unequal access to valuable goods may indicate social or economic differences, although no single feature proves a complete hierarchy. Weather, river length, and brick colour do not directly measure social status. Thus option A is correct.

Correct answer: B. Differences in economic status

Explanation: The governing concept is the use of settlement remains to study social and economic differentiation. When houses vary substantially in size or resources, the pattern may reflect unequal wealth, household roles, or access to labour and materials. It does not prove that everyone had equal property, that town planning was absent, or that farming ended. Because the question asks what the pattern may indicate, option B is the best answer, with the conclusion kept appropriately cautious.

Correct answer: C. Placing great wealth with the dead was not common

Explanation: The governing concept is interpreting burial practices through archaeological remains. Harappan graves usually contain relatively few goods, so the evidence suggests that placing lavish wealth with the dead was not a widespread custom. This does not prove that Harappans lacked wealth in life or that graves had another function. The pattern is about funerary practice, making option C the most accurate and appropriately limited conclusion.

Correct answer: A. To understand diet and animal husbandry

Explanation: Animal-bone analysis, or zooarchaeology, identifies species, age and sometimes sex, while cut, burning or butchery marks provide clues about diet and food preparation. The pattern of domesticated animals can also indicate husbandry. Hence option A is correct; bones do not directly construct streets, translate scripts or measure bricks.

Correct answer: A. Age, health and burial practice

Explanation: Bioarchaeological examination of human skeletons can estimate age and biological sex, identify signs of disease, injury or nutritional stress, and document the position and treatment of the dead. These observations make option A correct. Skeletons may offer broader social clues, but they do not by themselves determine trade routes, brick strength or drain direction.

Correct answer: A. Animal figures

Explanation: Harappan seals commonly carried a short inscription together with an animal motif. The so-called unicorn, along with bulls, elephants, and rhinoceroses, appears in this seal tradition. Palaces and battle scenes were not the usual accompanying designs, and human figures were less characteristic. Thus, animal figures in option A are correct.

Correct answer: B. Four to two to one

Explanation: The commonly observed Harappan brick ratio was 4:2:1 for length, width and height. This means that if the height was one unit, the width was two units and the length was four units. Such standardisation reflects shared construction practices across many settlements. Option A gives equal dimensions, while C and D do not show the characteristic Harappan proportion.

Correct answer: D. Town planning and sanitation

Explanation: City drains are structural evidence of how an urban settlement was organised. Their alignment, connections with houses, slope, covering, and outlets can show planning, water management, waste disposal, and concern for sanitation. Option D is correct because drainage belongs to the organisation of an urban centre. Drains alone cannot prove only religious beliefs, war policy, or language knowledge.

Correct answer: A. They may reveal symbols and beliefs

Explanation: Images on seals are visual archaeological evidence. Animal motifs may have represented symbols, identities, religious ideas, groups, or social meanings, although their exact interpretation must remain cautious because the script is not fully understood. Option A is correct because the figures can reveal symbolic and belief-related information. They do not accurately predict rainfall, teach modern languages, or function merely as decoration in every case.

Correct answer: C. The script has not yet been deciphered

Explanation: The governing concept is the limitation created by an undeciphered script. Harappan seals contain signs, but historians cannot yet read them with certainty, so the names, language, and precise meanings connected with many inscriptions remain uncertain. Thus, option C is correct. The seals are not modern, they are not necessarily too large, and the claim that they contain no signs directly contradicts the evidence.

Correct answer: A. Cultural contact and shared traditions

Explanation: The governing concept is comparative archaeological interpretation. When similar objects, designs or production standards occur across several Harappan cities, they may indicate interaction, movement of goods or ideas, and shared cultural practices. The evidence does not prove that every city was identical, but it supports the interpretation in option A. Isolation, absence of trade and modern origin contradict the archaeological context.

Correct answer: C. Continuity of building standards

Explanation: The governing idea is standardisation in construction. If bricks retain similar proportions and sizes across structures or successive building phases, this suggests that builders followed established measurements or shared technical conventions. Option C is therefore correct. Such evidence does not prove only religious similarity, the absence of planning, or that every building belonged to a separate period.
