early urban centres

Correct answer: A. Organised agricultural production

Explanation: The ploughed field discovered at Kalibangan is archaeological evidence of planned agricultural activity. Regular cultivation helped produce food surpluses that could support craft workers, traders, administrators and other urban groups. Therefore, organised agricultural production is the correct answer. Maritime trade, iron weapons and a monetary economy are not directly demonstrated by this field, and iron was not the defining technology of the Harappan period.

Correct answer: A. A shared construction tradition

Explanation: The repeated use of bricks with standard proportions suggests that builders across many Harappan settlements followed shared technical rules or construction practices. This points to coordination in building traditions, measurement and production. It does not by itself prove that every settlement was built simultaneously, occupied by one family, or completely uniform in religion. Nor does it establish a single political authority with certainty.

Correct answer: A. In drains and water-related structures

Explanation: Baked bricks were especially valuable in drains, wells, bathing areas and other structures exposed to water because firing made them harder, more durable and relatively resistant to moisture. Their use therefore reflects practical urban engineering and water management. Cotton fields and grazing areas did not require brick construction, while wooden toys were made from a different material. Thus option A best explains the archaeological pattern.

Correct answer: A. Identification and communication

Explanation: Although the Harappan script remains undeciphered, its presence on seals plausibly relates to identifying goods, individuals, groups or institutions and conveying brief information. Such functions would be useful in an urban economy with workshops, storage, exchange and administration. The evidence does not specifically show that seal inscriptions controlled irrigation, brick-making or animal husbandry. Because the exact meaning is uncertain, identification and communication should be understood as a probable interpretation.

Correct answer: A. Mutual dependence

Explanation: The governing concept is rural-urban interdependence. Farmers produced food and agricultural materials that sustained urban populations, while craftspersons transformed raw materials into pottery, tools, ornaments and other useful goods. These products could return to rural communities through exchange. Thus, option A is correct. Complete isolation, a purely military relationship and the absence of exchange contradict the evidence of connected economic activity.

Correct answer: A. Waste bins and soak pits

Explanation: The governing concept is planned urban sanitation. Archaeological remains from Harappan settlements include street and household drains, waste bins and soak pits that helped collect refuse and allow liquids to filter into the ground. Therefore, option A is correct. Open fields alone, direct disposal into the sea and no arrangement do not explain the organised drainage and waste-management features found at these sites.

Correct answer: A. Trapping solid waste

Explanation: The governing concept is basic drainage and sanitation technology. A settling jar or settling container slowed the flow of wastewater so that heavier solid particles could settle before the water entered the main drain. Consequently, option A is correct. It was not designed as a drinking-water vessel, a grain-measuring device or a workshop for making seals; those interpretations confuse sanitation features with unrelated activities.

Correct answer: A. It may also have served access control and flood protection

Explanation: The governing concept is cautious interpretation of archaeological structures. Raised platforms, walls and fortified sections may have restricted access, separated functional zones and reduced risks from flooding, even though defence could also have mattered. Hence option A is correct. Option B is too narrow, option C makes an unsupported absolute claim, and option D generalises about all towns without evidence. Archaeologists avoid assigning one certain function where several are possible.

Correct answer: A. Special location for important activities

Explanation: The governing concept is the relationship between urban space and social or administrative function. Placing major public buildings on an elevated section suggests that the area was deliberately selected for important communal, ceremonial or administrative activities. Thus, option A is correct. It does not mean that everyone lived there, that residences were absent from the city, or that the settlement was used only for farming. The evidence supports special use, not an absolute conclusion.

Correct answer: A. Differences in wealth and social status

Explanation: The governing concept is the use of architecture as evidence for social differentiation. Larger or more elaborate houses may have required greater resources and therefore can suggest differences in wealth, household size or social status. Option A is correct, but the word “possible” is important because house size alone cannot prove a complete hierarchy. The other options either claim equality, state ownership or warehouse use without supporting archaeological evidence.

Correct answer: A. Due to management of large populations and public facilities

Explanation: The governing concept is urban administration and coordinated public works. As populations grew and occupations became more diverse, authorities or community institutions had to organise water supply, drainage, streets, storage, sanitation, exchange and possibly security. Therefore, option A is correct. Agriculture did not disappear, festivals alone could not explain continuous administration, and different occupations—not identical work—made coordination more necessary.

Correct answer: A. Cleaning holes in drains

Explanation: The governing concept is the maintenance, not merely the construction, of urban infrastructure. Cleaning holes or access openings in drains made it possible to inspect, clear and repair channels when they became blocked. Thus, option A is correct evidence of planned upkeep. Animal motifs on seals, grave goods and plough marks provide information about identity, burial practices or agriculture, but they do not directly demonstrate the routine maintenance of public drainage.

Correct answer: A. From surrounding rural areas

Explanation: The governing concept is the interdependence of urban centres and their rural hinterlands. Harappan cities required regular supplies of grain, pulses, vegetables and other foods, which were produced by farming communities in nearby or connected rural areas and brought to the cities through exchange or redistribution. Therefore, option A is correct. Options B, C and D are too exclusive because food was not obtained only from foreign lands, forests or the sea.

Correct answer: A. Clay wheeled toy carts

Explanation: The governing concept is that everyday artefacts can reveal technology and movement. Clay models of wheeled carts show that the idea and construction of wheeled vehicles were known in early urban societies; they therefore provide evidence relevant to transport. Option A is correct. Stone pillars, grave pottery and reservoir steps may illuminate architecture, burial or water management, but they do not specifically demonstrate wheeled transport.

Correct answer: A. Providing water, fertile land and transport

Explanation: The governing concept is the geographical foundation of early urbanisation. River valleys supplied water for people and animals, supported cultivation through fertile alluvial soils, and offered routes for communication and movement of goods. These combined advantages helped sustain dense settlements and urban growth, so option A is correct. Rivers did not provide only stone, increase sea storms or prevent farming; therefore B, C and D contradict the evidence.

Correct answer: A. Local resources and environments differed

Explanation: The governing concept is regional adaptation in urban construction. Builders used materials available in their surroundings, while soil, stone, water supply and climate also affected techniques and designs. Therefore, differing local resources and environments best explain the variation. Option B is too absolute because Harappan settlements had contacts; C has no supporting evidence, and D concerns writing rather than construction.

Correct answer: A. Decline in standardised seals and weights

Explanation: The governing concept is the transformation of the Harappan urban system after about 1900 BCE. A reduction in standardised seals and weights suggests that the wide administrative and commercial networks associated with mature cities weakened. Thus option A is correct. The other choices describe expansion, increased writing, or universal construction, none of which is a recognised general sign of this decline.

Correct answer: A. There was regional transformation rather than complete disappearance

Explanation: The governing concept is continuity amid urban transformation. If rural settlements continued after major cities weakened, then population, farming and cultural practices did not simply disappear; ways of living changed unevenly across regions. Option A captures this evidence-based conclusion. B, C and D are overstatements because continued rural settlement directly indicates that people, agriculture and elements of culture persisted.

Correct answer: A. Combined study of evidence on planning, economy, environment and society

Explanation: The governing concept is a multidisciplinary interpretation of early urbanism. Combining evidence about town planning, production and exchange, environmental conditions, and social life gives a fuller and more balanced picture; therefore option A is correct. Studying only monuments overlooks ordinary life, later texts may be distant from the period, and one object cannot represent an entire city or society.

Correct answer: A. They helped safely store grain and other goods

Explanation: Storage facilities were important because urban settlements needed places to collect, protect, and manage agricultural produce and other goods. Such structures can be connected with food security, redistribution, and the wider economic organisation of Harappan cities. Option A is the best answer. The evidence does not support defining them only as religious spaces, military training grounds, or barriers for drain water.

Correct answer: B. Technical adaptation to the environment

Explanation: Dholavira’s reservoirs, channels, and methods of collecting seasonal water demonstrate that its inhabitants designed technology in response to a dry and variable environment. This is evidence of environmental adaptation, making option B correct. The system was intended to secure freshwater, not prepare for naval warfare. It also does not prove that farming was completely absent or that trade ended; those claims go beyond the evidence.

Correct answer: A. They provided a base of food and population

Explanation: The governing concept is the relationship between agricultural settlements and urbanisation. Permanent farming communities produced relatively regular food supplies and supported settled populations, including workers, administrators, traders, and craft specialists. Agricultural surplus could help sustain towns and permit forms of specialised production and exchange. Such settlements did not end trade, make cities nomadic, or stop crafts. Therefore, option A is correct because food and population formed an important base for early urban growth.

Correct answer: A. Separating important activities from ordinary residences

Explanation: The governing concept is spatial organisation in an early urban settlement. Harappan sites often show a raised citadel area containing important or public structures, while the lower town contained many residential and occupational areas. Therefore, separating the two zones probably helped distinguish special activities from ordinary housing. It does not imply that farming or trade stopped, nor that the city was abandoned.

Correct answer: A. Drainage was an integral part of town planning

Explanation: The governing concept is integrated town planning. When streets and drains were laid out together, water flow, household discharge and movement through the settlement had been considered as connected needs. This supports the conclusion that drainage formed an essential part of urban design from an early stage. The evidence does not show that drains were late additions, that streets were only religious, or that the cities received no rain.

Correct answer: A. Ease and uniformity in construction

Explanation: The governing concept is standardisation in urban construction. Bricks made in consistent proportions could fit together predictably, simplify planning and repairs, and promote a broadly uniform building method across Harappan settlements. This practical advantage explains ease and uniformity in construction. Standard proportions were not primarily intended to decorate bricks, raise agricultural output, or manufacture seals, which were separate activities and objects.
