early urban centres

Correct answer: A. Arid environment and limited water availability

Explanation: The governing concept is environmental adaptation. Dholavira was located in a relatively arid region where dependable freshwater was limited and rainfall could be seasonal. Large reservoirs allowed people to collect and store runoff or rainwater for use during drier periods. Heavy snowfall, dense forests and ocean tides do not explain the settlement’s main need for storage tanks, so option A best connects geography with urban water management.

Correct answer: A. Providing water to ordinary residents

Explanation: The governing concept is the social role of shared civic infrastructure. Public wells could provide accessible water to residents, especially households that did not possess a private well. This suggests that urban facilities served ordinary inhabitants as well as supporting daily community life. The evidence does not indicate that wells were reserved only for rulers, used to hide merchandise, or intended to block roads; therefore option A is correct.

Correct answer: A. Remains of staircases

Explanation: The governing concept is archaeological inference from architectural remains. A staircase is a structural feature designed to connect different levels, so its surviving base or steps provide reasonable evidence that a house may have had an upper storey. Wide streets describe the surrounding settlement, while pots in graves and standardised weights relate to other aspects of Harappan life and cannot directly establish the height of a house.

Correct answer: A. Organised water and waste management

Explanation: The governing concept is the connection between population growth and civic infrastructure. As more people lived close together, the settlement needed dependable water supplies and organised ways to remove wastewater and solid refuse. Without such arrangements, crowding would increase health and sanitation problems. Hunting grounds, nomadic camps and forest expansion do not meet the everyday infrastructure needs of a permanent, growing urban population, so option A is correct.

Correct answer: A. Their wide use in cooking, storage and serving

Explanation: The governing concept is how archaeologists infer everyday life from the quantity and distribution of artefacts. Harappan pottery served common domestic purposes: cooking food, storing grain or liquids, and serving meals. Its widespread use explains the large quantities recovered, so option A is correct. Pottery was not used mainly for roads or standard weights, and it was not limited to religious figurines; therefore B, C and D are unsuitable.

Correct answer: A. They could carry heavy goods and farm produce

Explanation: The governing concept is the relationship between urban centres and their rural hinterlands. Bullock carts provided dependable land transport and could carry heavy loads such as agricultural produce, raw materials and manufactured goods between villages and cities. Hence option A is correct. They were not ocean-going vehicles, were not restricted to rituals, and did not smelt metal; those claims confuse transport with maritime travel, religion or metallurgy.

Correct answer: A. To preserve goods for a large population and trade

Explanation: The governing concept is the connection between urban growth, agricultural surplus and storage. A larger population, specialised workers and trading activity required grain, raw materials and finished goods to be kept safely for later use. Therefore, option A is correct. Option B contradicts the basic need to feed city residents, while C is false because urban communities were settled. Option D reverses the purpose of storage: produce was preserved, not destroyed.

Correct answer: A. For milk, meat, leather and transport

Explanation: The governing concept is the interdependence between urban centres and their rural hinterlands. Herded animals supplied milk and meat, hides provided leather, and draught or pack animals supported transport and agricultural work. Thus option A correctly identifies several practical needs rather than a single use. Option B is too narrow, while C and D confuse animal products with writing materials or construction materials, which were obtained through other processes.

Correct answer: A. Economic and social specialisation

Explanation: The governing concept is division of labour within an urban economy. Artisans, merchants, administrators, builders and other workers performed different specialised tasks, making production and exchange more organised. Therefore, option A is correct: occupational variety reflects economic specialisation and related social differentiation. Option B denies the observed division of work, C reverses the meaning of urban development, and D is incorrect because traders and exchange were part of city life rather than disappearing.

Correct answer: A. Special wealth or status of some people

Explanation: The governing concept is cautious inference about social differentiation from unequal access to valuable goods. If rare ornaments were available only to some people, they may reflect differences in wealth, prestige or social position; therefore option A is correct. The evidence suggests a possibility, not a complete description of the social hierarchy. B claims equality without proof, C ignores the value and use of ornaments, and D incorrectly denies the trade needed to obtain rare materials.

Correct answer: A. Organised labour and resources

Explanation: The governing concept is collective organisation for large-scale urban construction. Drains, walls, reservoirs and other public works required building materials, planning, skilled knowledge and the coordinated labour of many people. Thus option A is correct. One family could not normally complete such extensive projects, nomadic hunters were not the relevant workforce, and a foreign army is not required to explain civic construction. The evidence supports organised urban management and resource mobilisation.

Correct answer: A. Few windows and entrances facing main streets

Explanation: The governing concept is residential planning for privacy. Harappan houses generally limited direct openings towards major streets and often used entrances opening into lanes or courtyards. This reduced public visibility inside the home, so option A is correct. An open entrance, street-facing rooms, or houses without walls would increase exposure rather than protect household privacy.

Correct answer: A. They could carry heavy goods relatively easily

Explanation: The governing concept is comparative transport efficiency. Boats and other watercraft could carry bulky or heavy cargo over considerable distances with less effort than moving the same load entirely by land. Therefore, option A is correct. River routes were not limited to pedestrians, did not prevent agriculture, and generally connected settlements rather than isolating them. Their usefulness still depended on navigability, season and local geography.

Correct answer: A. Traders and administrative groups

Explanation: The governing concept is the organisation of agricultural surplus in an urban economy. Farmers produced more food than they immediately consumed, and this surplus had to be collected, stored and redistributed to craftspeople, workers and other residents. Traders could assist in exchange, while administrative groups could organise collection and allocation. The evidence does not identify one certain institution, so this is a reasoned inference. Hunters, children and nomadic performers do not plausibly represent the main distribution system.

Correct answer: A. Agricultural surplus, craft specialisation, trade and town planning

Explanation: The governing concept is that urbanisation is a multi-factor process. Agricultural surplus could support people who were not directly farming; craft specialisation supplied tools, ornaments and other goods; trade connected producers with materials and markets; and town planning organised streets, drainage, buildings and shared infrastructure. No single feature explains urban success by itself. Monumental buildings, figurines or foreign contacts may provide evidence, but each alone is insufficient. Thus option A offers the most complete explanation.

Correct answer: A. Supporting non-farming craft workers and traders

Explanation: Agricultural surplus means production beyond the immediate needs of farming households. It could feed craft workers, traders, administrators, builders, and other urban residents who were not producing their own food full-time. Therefore option A explains the economic foundation of urban life. Surplus was not primarily for palace decoration, changing river channels, or deciphering seals; those options do not explain sustained food provision.

Correct answer: A. An economy with specialised craft production

Explanation: Evidence such as bead blanks, drills, furnaces, unfinished pieces, and production waste indicates that skilled workers practised bead-making as a specialised activity at Chanhudaro. This supports option A and also suggests division of labour, access to raw materials, and exchange networks typical of an urban economy. The evidence is inconsistent with an economy based only on subsistence farming, nomadism, or military production.

Correct answer: A. A system of regular maintenance

Explanation: The governing concept is civic infrastructure management. Cleaning holes or access points would allow people to inspect, clear, and repair channels after construction, showing that drainage was expected to operate over time and required organised maintenance. They were not merely decorative and did not transform drains into religious places. Nor would such openings make wastewater safe to drink; therefore option A correctly identifies the administrative need.

Correct answer: A. Decentralised access to water

Explanation: The governing concept is the distribution of urban services. Many wells located across Mohenjodaro would have supplied water to different neighbourhoods, households, or public spaces rather than forcing every resident to depend on one central source. This indicates decentralised and relatively local access to water. The finding does not show exclusive reliance on the river, absence of drains, or farming inside the city; therefore option A is correct.

Correct answer: A. A functional division between movement routes and residential areas

Explanation: The governing historical concept is functional urban planning. Broad main streets could accommodate movement, circulation, and access across the settlement, while narrower lanes could serve homes and local residential access. Option A is the most reasonable interpretation because the contrast in widths suggests differentiated functions. The evidence does not prove an absence of planning, exclusive religious use, or an uninhabited lower town.

Correct answer: A. Incorporation of external contacts into local life

Explanation: The governing concept is cultural interaction through contact, exchange, and selective adoption. Foreign objects found together with local goods suggest that outside connections entered the city’s economic or social life while local practices continued. Therefore, incorporation of external contacts into local life is correct. The evidence does not by itself prove that local culture ended, that the city declined, or that foreigners ruled it.

Correct answer: A. Disruption of water supply and transport routes

Explanation: The governing concept is the connection between environmental change and urban economies. A shifted river channel could move water away from settlement areas and make established boat or transport routes unusable. That would directly affect domestic supply, farming, exchange, and movement of goods. A change in fortification, script, or jewellery demand does not follow immediately or necessarily from a river shift. Therefore, option A is correct.

Correct answer: A. Cities could differ in function, resources and population density

Explanation: The governing concept is multidimensional comparison of urban centres. Physical area alone does not reveal whether a city served as a craft hub, trading station, administrative centre, ritual place, or agricultural settlement. Cities of similar size could have different population densities, resources, infrastructure, and regional connections. Thus option A is correct. The other choices are either factually false or wrongly dismiss the importance of smaller settlements.

Correct answer: A. Different water strategies were adopted according to local environments

Explanation: The governing concept is technological adaptation to local environmental conditions. Reservoirs may store collected or seasonal water, whereas wells provide access to groundwater; the choice depends on geology, rainfall, terrain, and settlement needs. Similar city size does not prove equal population, and different systems do not show that one city was more civilised or that the other lacked management. Hence option A is correct.

Correct answer: A. Collective coordination in construction

Explanation: The governing concept is early urban planning and coordinated management. Streets laid out with consistent directions, widths, or connections could not usually result from isolated household decisions; they required shared rules, labour, and some form of public coordination. Therefore, option A is correct. Private house planning cannot explain the wider street pattern, while absence of rules contradicts the regular layout and purely ritual direction is not demonstrated by streets alone.
