early urban centres

Correct answer: D. Entry of light and air

Explanation: The governing concept is the climatic and functional design of domestic space. An internal courtyard allowed sunlight and fresh air to reach rooms that had few openings toward public streets. It could also support household work and social activities. Therefore option D is correct. Grain weighing, animal sacrifice and military training were not the primary architectural purpose of a residential courtyard.

Correct answer: C. Advanced civic organisation

Explanation: A coordinated water-supply and drainage network required planning, construction skills, maintenance, and rules for managing shared urban facilities. Its simultaneous development therefore points to advanced civic organisation, making option C correct. Religion, trade, or military authority might have influenced society, but the infrastructure itself does not prove that any one of those alone controlled the cities.

Correct answer: B. To supply a large urban population

Explanation: Harappan cities contained many people who were not directly producing food, including craft workers, traders and administrators. Stored grain helped maintain a regular food supply when harvests were seasonal or transport was difficult. Storage therefore supported urban life and distribution rather than religious display alone. It was not intended specifically for foreign rulers and certainly did not keep cities empty. Option B is correct.

Correct answer: C. To feed non-farming craft workers and urban residents

Explanation: An agricultural surplus means that food production exceeded the immediate needs of farming households. This extra produce could support craft workers, traders, builders and other urban residents who performed specialised tasks instead of farming full time. Such economic specialisation helped cities grow and function. The surplus was not produced only for temple decoration, animal purchases or army expansion. Therefore, option C is correct.

Correct answer: D. Wells and river water

Explanation: Wells and rivers were accessible freshwater sources that could help Harappan farmers water fields, especially when rainfall was insufficient or seasonal. Archaeological evidence also indicates varied agricultural practices across the Harappan region, so irrigation methods may not have been identical everywhere. Glaciers were not practical direct irrigation sources, seawater harms most crops, and artificial rain was unavailable. Option D is correct.

Correct answer: A. From a field with plough marks in two directions

Explanation: At Kalibangan, archaeologists found a ploughed field with furrows running in two directions. This arrangement is interpreted as evidence that two crops could be sown in separate rows within the same field, an example of double cropping or mixed cultivation. A circular, stony or soil-less field does not provide this agricultural evidence. Hence, option A is correct.

Correct answer: A. Collective planning and labour organisation

Explanation: The governing historical concept is urban organisation in the Harappan civilisation. Large drains, reservoirs, wells, streets, and other public structures required decisions about design, materials, labour, maintenance, and shared use. Their scale therefore points to collective planning and organised labour rather than isolated personal effort. Such construction does not prove that cities lacked contact or that agriculture ended. Option A is correct because public works reveal coordinated urban management.

Correct answer: A. To allow water to flow naturally

Explanation: The governing principle is gravity-based drainage. A carefully constructed slope allowed wastewater and rainwater to move from higher points towards lower outlets without continuous manual pumping. Therefore, option A is correct. Drains were channels for carrying water, not for storing grain, raising walls, or drying seals; those alternatives do not explain why a gradient was needed.

Correct answer: A. Long-term and continuous occupation

Explanation: The governing concept is settlement continuity inferred from archaeological layers and building history. When houses are repaired, modified and rebuilt on the same foundations, people were returning to or remaining in those locations over an extended period. This supports long-term occupation of the urban settlement. The evidence does not suggest that cities appeared in one day, that houses were unused, or that all inhabitants were nomadic. Therefore, option A best explains the archaeological observation.

Correct answer: D. Identifying goods

Explanation: Harappan seals are commonly interpreted in relation to the identification, marking or management of goods and consignments. Their impressions could have helped indicate ownership, authority or the contents of a package. Therefore option D is the best answer. Ploughing, breaking walls and cooking grain are practical activities unrelated to the probable administrative or commercial use of seals.

Correct answer: B. An organised urban society

Explanation: Specialist craftspersons imply that some people could devote much of their time to particular skills rather than producing everything they needed themselves. Such specialisation requires a dependable food supply, exchange networks and social coordination, features commonly associated with organised urban settlements. Option B is correct. Nomadism, exclusive hunting and absence of technology do not explain sustained specialist production.

Correct answer: C. Major cities

Explanation: Harappa and Mohenjodaro were major urban centres of the Harappan Civilisation. Their planned streets, substantial brick structures, drainage systems, craft areas and evidence of organised settlement distinguish them from small villages, temporary markets or pastoral camps. Therefore, option C is correct because both sites represent developed cities with complex urban features and large populations.

Correct answer: A. Planned urban layout

Explanation: Harappan cities are generally recognised for planned urban layouts. Streets were often arranged systematically, and houses were connected to organised drainage channels made with durable materials. This evidence reflects civic planning rather than random settlement. Therefore, option A is correct. Irregular lanes, huts alone and houses without drains contradict the archaeological evidence of developed Harappan urban centres.

Correct answer: A. Citadel

Explanation: The elevated and often fortified part of a Harappan city is commonly called the citadel. It was distinct from the lower town and may have contained important public or administrative structures, although functions varied by site. Therefore, option A is correct. A market, field or port is not the general name for this raised urban section. The contrast between citadel and lower town is central to understanding Harappan city planning.

Correct answer: D. Major urban centres

Explanation: The governing concept is the classification of settlements by scale, planning and complexity. Harappa and Mohenjo-daro had extensive built areas, planned streets, public architecture and evidence of specialised activities, so they are major urban centres. Option D is therefore correct. They were not temporary camps or merely ritual sites, and their size and infrastructure distinguish them from small agricultural villages.

Correct answer: D. Organised town planning

Explanation: The governing concept is urban planning. Streets and lanes laid out in an organised pattern show that settlement space was deliberately designed rather than growing entirely without coordination. Such evidence points to civic planning and an urban way of life. Hence, option D is correct. The layout does not by itself prove only rural life, only religious activity, or only military power; those choices are too narrow.

Correct answer: A. The original context of objects may be disturbed

Explanation: The governing concept is archaeological context and stratigraphy. Farming, ploughing, and repeated turning of soil can move artefacts away from the layers and locations in which they were originally deposited. Historians must therefore record the disturbance and interpret the evidence cautiously. Option A is correct; the disturbance does not prove that objects are new, that the site is imaginary, or that excavation has no value.

Correct answer: A. Well-planned cities

Explanation: A major feature of the Harappan Civilization was its well-planned urban layout. Its cities had an organised street grid, baked-brick buildings, and covered drainage channels. Therefore, the option stating that there was no drainage system is incorrect. Exam tip: Remember Harappan cities for grid planning and advanced drainage.
