early urban centres

Correct answer: B. Agriculture, crafts and trade

Explanation: The governing concept is the economic foundation of early urban centres. Harappan cities depended on agricultural production for food, specialised crafts for items such as beads and pottery, and exchange networks for obtaining raw materials and distributing goods. Therefore, option B is correct. Hunting, military service or piracy alone could not support the sustained population, workshops and public works of large cities.

Correct answer: A. They often met at right angles

Explanation: A common feature of Harappan urban planning was a grid-like street arrangement in which major and minor roads often intersected at approximately right angles. This reflects deliberate surveying and organised settlement design, so option A is correct. Harappan streets were not exclusively circular or underground, and they served neighbourhoods, houses, drains, and activity areas rather than leading only to a palace.

Correct answer: A. Drains were covered and interconnected

Explanation: A major feature of Harappan sanitation was the planned connection of household drains with larger street drains. Many drains were covered and could be maintained through openings, showing organised urban management. Therefore, option A is correct. The system was not confined to the citadel, it clearly existed, and its principal construction was not wooden, so options B, C, and D are incorrect.

Correct answer: A. Onto narrow lanes

Explanation: Many Harappan house entrances opened onto narrow side lanes rather than directly onto major streets. This arrangement was practical because it supported privacy, reduced congestion, and fitted the planned street network. Therefore, option A is correct. Entrances did not normally open into a river, onto a citadel roof, or simply through the outer city wall; those choices are inconsistent with domestic urban planning.

Correct answer: A. Organised water supply

Explanation: The discovery of many private and public wells indicates that Harappan settlements maintained regular and organised access to water. Wells supported household needs and urban life, although they were only one part of broader water management. Thus, option A is correct. Their presence does not specifically prove naval warfare, iron production, or religious rituals only, so options B, C, and D are unsuitable.

Correct answer: A. For large reservoirs and water management

Explanation: Dholavira is especially notable for its large reservoirs, channels, and other structures designed to collect, store, and manage water. These features show how Harappan planners adapted urban life to local environmental conditions. Therefore, option A is correct. Iron weapons and paper production belong to later or different technological contexts, while stone temples are not the defining achievement associated with Dholavira.

Correct answer: A. Standardisation in construction

Explanation: Uniformly proportioned bricks indicate that builders followed shared measurements and established construction standards across many Harappan settlements. Such standardisation suggests coordination, technical knowledge, and organised urban production. Hence, option A is correct. It does not prove that agriculture was absent, that all buildings were religious, or that the cities were under foreign rule; those conclusions do not follow from brick dimensions alone.

Correct answer: A. Organised labour and planning

Explanation: Public works such as drainage systems, reservoirs, wells, streets and large platforms could not normally have been built without planning, technical coordination and the mobilisation of labour beyond a single household. They therefore indicate organised urban activity and some form of administrative coordination. The evidence does not prove a particular ruler, while options B, C and D contradict the scale and permanent character of these constructions.

Correct answer: A. Sanitation and waste management

Explanation: Waste bins collected refuse, while soak pits helped absorb or dispose of wastewater. Together, these features show organised urban sanitation and an effort to manage waste within settled communities. Thus option A is correct. They were not defensive structures, ritual installations, or direct evidence of metal exchange. Their presence reflects practical civic planning and concern for cleanliness in Harappan urban centres.

Correct answer: A. For regular maintenance and removal of blockages

Explanation: Cleaning holes made it possible to inspect drains, remove accumulated dirt, and clear blockages without dismantling the entire drainage line. This demonstrates that Harappan builders planned not only the construction of drains but also their continued maintenance. Option A is therefore correct. Lamps, grain storage, and hiding seals do not explain the position or practical design of these openings.

Correct answer: A. Protection from floods and waterlogging

Explanation: A raised platform lifted a building above ground level, reducing the risk that floodwater or persistent waterlogging would damage its foundations and interior. This is an example of adapting urban construction to local environmental conditions. Option A is correct. Raising a structure does not bring it meaningfully closer to the sun, and the feature was not primarily for tying horses or growing crops.

Correct answer: A. Extensive use of stone at Dholavira

Explanation: Dholavira is known for the extensive use of stone in walls, reservoirs, and other structures, reflecting the availability of suitable local material. This illustrates regional variation within the Harappan cultural sphere. Option A is correct. The other choices make absolute claims about every city or introduce marble, which was not a universal Harappan building material.

Correct answer: A. Social and economic differentiation

Explanation: Marked differences in house size may reflect unequal access to resources, varying household status, or different family needs. Archaeologists therefore use this pattern as possible evidence of social and economic differentiation, not as conclusive proof of a rigid class system. Option A is correct. Equal wealth would not explain the contrast, and the evidence does not show that only kings lived there or that the city was temporary.

Correct answer: A. From surrounding farming and pastoral areas

Explanation: The governing concept is the economic interdependence of an urban centre and its rural hinterland. Farmers and pastoralists in surrounding regions produced grains, animals and other foods that supported dense town populations. Therefore option A is correct. Maritime trade, hunting and foreign empires might have contributed occasionally, but they could not be the sole or main food source.

Correct answer: A. It supported non-farming groups

Explanation: The governing concept is surplus and urban specialisation. When agriculture produced more food than farming families immediately needed, part of it could support craftspersons, traders, administrators and other non-farming groups. This enabled a permanent urban population, so option A is correct. The other choices contradict the way surplus encouraged trade, crafts and city growth.

Correct answer: A. Exchange of food and raw materials

Explanation: The governing concept is urban-rural interdependence. Rural communities supplied food, fuel and raw materials such as stone, wood, metals or shell, while towns processed materials and circulated crafted goods through exchange networks. Option A correctly describes this two-way relationship. Complete isolation and no relationship are false, while military control alone cannot explain economic evidence.

Correct answer: A. From settlement area and housing density

Explanation: The governing concept is archaeological estimation of population. Historians examine the total settlement area, the number and size of houses, and the likely number of people each dwelling could accommodate. These indicators provide an informed estimate, although they cannot give an exact census. The number of seals, graves, or grains alone is insufficient because each represents only one type of evidence and may not reflect the whole population. Therefore, option A is correct.

Correct answer: A. Decline in large cities and standardisation

Explanation: The governing historical idea is the transformation of urban life after about 1900 BCE. Archaeological evidence points to the decline of some large urban centres, reduced use of standardised bricks and weights, and the growth of smaller or more regional settlements. This was not an identical change everywhere, and it should not be reduced to a claim that all cities vanished. The other options assert trends not supported by the broad pattern. Hence, option A is correct.

Correct answer: A. As a multi-causal and regional transformation

Explanation: The governing concept is a multi-causal and regionally varied explanation of historical change. Evidence may point to interacting factors such as shifts in climate or river courses, changes in trade networks, pressure on resources, and local social or economic conditions. The decline was not necessarily simultaneous everywhere, so a single invasion or one-day catastrophe is too simplistic. Nor can historians deny that major changes occurred. Therefore, option A is the best answer.

Correct answer: A. Functional zoning

Explanation: The governing concept is functional zoning, meaning that different parts of a city are used for different purposes. If craft production, residence, storage, or public activities are concentrated in separate areas, the settlement reflects planning and an organised use of space. This does not describe nomadic movement or the expansion of farmland. It also contradicts the claim that town planning was absent. Therefore, the presence of specialised areas makes option A correct.

Correct answer: A. Growth of specialised occupations beyond agriculture

Explanation: The governing concept is division of labour associated with urbanisation. Traders and craftspersons performed specialised activities such as making goods, processing materials, and exchanging products, rather than relying only on farming. Their presence suggests a more differentiated economy and links between producers, consumers, and rural suppliers. It does not mean everyone farmed, that exchange ended, or that villages disappeared. Hence, option A correctly identifies the economic change.

Correct answer: A. Agricultural surplus

Explanation: The governing concept is the relationship between agricultural surplus and urbanisation. When farming communities produced more food than they immediately needed, the surplus could support craftspeople, traders, administrators, and other non-farming groups in towns. Therefore, option A is correct. Hunting alone could not reliably sustain large cities, foreign rule is not an economic base, and iron coins do not explain the earliest urban growth.

Correct answer: A. For light, ventilation and household activities

Explanation: The governing concept is the relationship between domestic architecture and daily life. A central courtyard could bring daylight and ventilation into surrounding rooms while providing space for household work and interaction. Therefore, option A is correct. Military training, tax storage, and shipbuilding are specialized activities that do not fit the ordinary residential context of these courtyards.

Correct answer: A. Into the main street drain

Explanation: The governing concept is the integrated drainage system of Harappan cities. Household bathroom outlets generally connected to smaller channels that led into larger, often covered drains along the streets. Therefore, option A is correct. Wells supplied water and were not intended for wastewater disposal; granaries and roofs had different functions and were not drainage destinations.

Correct answer: A. Some houses had independent access to water

Explanation: The governing concept is household access to urban resources. Private wells show that at least some households could obtain water independently within or near their homes. Hence option A is correct. Their presence does not prove that temples alone had water or that public sources were absent, and wells were functional installations rather than mere decoration.
