early urban centres

Correct answer: A. Large reservoirs

Explanation: Dholavira contained large reservoirs designed to collect and store rainwater and runoff from nearby channels. These structures demonstrate planned water conservation suited to the region’s dry environment. Household pots could hold small quantities of water, but they were not city-scale infrastructure. Ships and underground palaces have no connection with the excavated water-management system.

Correct answer: B. In construction

Explanation: Stone was widely used for construction at Dholavira, including buildings, walls, and water-management structures. Its extensive use is a notable feature of the site, although bricks and other materials were also employed. Textile production, farming, and writing were different activities; the presence of stone mainly reflects architectural and engineering practices rather than those occupations.

Correct answer: C. Signboard

Explanation: The large-letter object discovered at Dholavira is commonly called a signboard because it carried prominent Harappan signs arranged for display. Its precise message and function cannot be established because the Harappan script remains undeciphered. It is therefore not securely identifiable as a royal order, religious book, or war record; “signboard” is the accepted descriptive term.

Correct answer: D. Sabarmati

Explanation: Lothal was situated near a tributary of the Sabarmati River in Gujarat. This location connected the settlement with inland routes and helped support contact with the Gulf and wider maritime networks. The Sutlej, Ganga, and Narmada are important rivers, but they are not the river system associated with Lothal in this question. Thus, option D is correct.

Correct answer: A. Maritime trade

Explanation: The dockyard-like structure at Lothal is commonly associated with maritime trade and movement of goods by water. Its location near a river channel and the presence of craft and exchange evidence support this interpretation, although scholars discuss details of its exact function. Hill farming, religious education, and hunting do not explain the structure’s water-related design or commercial context.

Correct answer: B. From nearby rural areas

Explanation: The governing concept is the economic interdependence of urban centres and their surrounding countryside. Farmers in nearby rural settlements cultivated grain and supplied it to towns, where many people were engaged in crafts, administration or trade rather than farming. Hence option B is correct. Sea ships and foreign lands were not the normal main source, and the citadel was an urban zone, not an agricultural supply region.

Correct answer: C. Wheat

Explanation: The governing concept is the reconstruction of ancient agriculture from archaeological remains such as charred grains and farming evidence. Wheat was a major Harappan crop, often discussed along with barley, pulses and regionally grown millets. Thus option C is correct. Tea, coffee and rubber are not characteristic major crops of the Harappan agricultural system; they are much later or unsuitable alternatives in this context.

Correct answer: D. Cotton

Explanation: The governing concept is the use of cultivated plants for textile production. Harappan communities knew cotton as a fibre crop and used its fibres to make textiles; evidence from the civilisation is among the early indications of cotton use in the region. Therefore option D is correct. Wool is an animal fibre, while silk and jute are not the intended Harappan fibre crop in this question.

Correct answer: A. Farming and transport

Explanation: The governing concept is the role of domesticated animals in the Harappan agricultural economy. Bulls could assist with ploughing and other farm work, and they could pull carts used to move people or goods. Therefore option A is correct. Bulls were not used for sea travel, writing, or firing bricks; those alternatives confuse animal use with unrelated activities or technologies.

Correct answer: B. Urban sanitation system

Explanation: The governing concept is urban civic infrastructure. Drains along streets carried wastewater away from houses and public spaces, often forming part of a planned network with channels, junctions, and access points for maintenance. Therefore, option B is correct. Such drains primarily served sanitation and waste management; they were not military works, religious installations, or agricultural irrigation canals.

Correct answer: C. Remains of walls and rooms

Explanation: The governing concept is the archaeological interpretation of material remains. Surviving walls, rooms, courtyards, entrances, floors, hearths, and drains help researchers reconstruct the plan and possible uses of Harappan houses. Hence, option C is correct. Folk songs and modern maps are not the primary evidence for ancient layouts, and coins alone could not reveal the arrangement of rooms.

Correct answer: A. Streets intersecting at right angles

Explanation: The governing concept is planned urban layout. When streets run in straight lines and intersect at right angles, they form a regular grid, showing deliberate town planning rather than random growth. Therefore, option A is correct. Circular houses, the absence of walls, or single-storeyed buildings do not by themselves demonstrate a grid plan.

Correct answer: A. It was mainly a residential area

Explanation: The governing concept is the functional division of Harappan cities into distinct urban zones. The lower town generally contained houses, streets, wells, and everyday facilities for residents. Hence option A is correct. It was not simply a royal cemetery, a seaport, or farmland; those descriptions do not represent its main urban function.

Correct answer: A. Maintaining sanitation and preventing accidents

Explanation: The governing concept is civic sanitation in a planned city. Covering drains helped contain wastewater, reduce exposure to foul smells and contamination, and lower the risk of people or objects falling into them. Thus option A is correct. Decoration, grain storage, and ritual use were not the principal purposes of these drainage covers.

Correct answer: A. By planned cities and public structures

Explanation: The governing historical method is to identify urbanism through archaeological evidence and settlement organisation. Harappan urban centres show planned streets, standardised construction, drainage, specialised buildings, and other public structures, indicating coordinated civic activity. Therefore, option A is correct. Religious stories alone are not archaeological proof, hunting tools are only one type of object, and Harappan urban settlements were not defined only by hill locations.

Correct answer: B. North-western Indian subcontinent

Explanation: The governing geographical concept is the distribution of Harappan archaeological sites. The civilisation was concentrated across the north-western Indian subcontinent, including areas in present-day Pakistan and north-western India, with sites extending across a broad region. Thus option B is correct. It was not limited to South India, Eastern India, or Central Asia, although its wider networks had contacts beyond the core area.

Correct answer: C. Similar brick ratios and town planning

Explanation: The governing concept is standardisation in Harappan urban culture. Bricks at many settlements commonly followed a similar length-to-width-to-thickness ratio, while streets, drains and building layouts also show planning. These repeated features support cultural and administrative uniformity. Therefore, option C is correct; different scripts, unequal bricks and similar trees are not evidence of this shared urban pattern.

Correct answer: D. In drains and important buildings

Explanation: The governing concept is the functional use of durable construction material. Baked bricks resisted moisture and retained strength better than ordinary mud bricks, so Harappan builders used them in drains, wells and significant structures. Option D is correct because it identifies genuine architectural uses. Toys, ornaments and farming tools were made from other materials and were not the principal purpose of baked bricks.

Correct answer: A. For constructing walls and platforms

Explanation: The governing concept is the use of locally available materials in urban construction. Mud bricks, made from moulded and sun-dried clay, were widely used for walls, foundations and raised platforms. Thus option A is correct. Metal smelting and bead polishing required specialised facilities, while Harappan writing appeared on seals, pottery and other objects rather than on mud-brick structures.

Correct answer: B. Circular

Explanation: The governing concept is the archaeological identification of Harappan water-management structures. Most excavated Harappan wells were circular, with bricks carefully laid in successive rings to support the shaft and withstand pressure from the surrounding soil. Therefore option B is correct. Square, triangular and star-shaped forms do not represent the usual plan of these wells.

Correct answer: C. For collecting wastewater and solid waste

Explanation: The governing concept is urban sanitation and controlled wastewater disposal. Soak pits received wastewater and trapped sediments or solid matter before the flow reached larger drains, reducing blockages and helping keep streets cleaner. Option C is correct. Grain storage, seal production and animal keeping required separate spaces and were not the function of soak pits.

Correct answer: D. To main drains

Explanation: The governing concept is a hierarchical drainage network. Small drains carrying wastewater from houses and lanes joined larger main drains, allowing water to move away from residential areas in an organised manner. Option D is correct. Wells supplied water rather than receiving routine wastewater, and granaries or citadel walls were not the normal endpoints of household drains.

Correct answer: A. To allow water to flow

Explanation: The governing concept is the use of gradient in civil engineering. A slight, continuous slope uses gravity to move wastewater through a drain toward a soak pit or larger channel, reducing stagnant water and blockage. Therefore option A is correct. Decoration, bead drying and grain weighing do not explain why the channels themselves needed a slope.

Correct answer: B. Towards internal lanes

Explanation: The governing concept is the relationship between house design and planned street layout. Many Harappan entrances opened onto smaller internal lanes rather than directly onto broad main streets. This arrangement helped organise movement and reduced interference with major routes. Option B is correct; rivers, citadel walls and fields were not the usual orientation of residential entrances.

Correct answer: C. To maintain privacy

Explanation: The governing concept is the private and inward-looking design of many Harappan houses. Limiting windows on main-street façades helped protect household privacy and reduced direct visual contact with public movement. Internal courtyards could still provide light and ventilation. Thus option C is correct; blocking all light, stopping rain and saving bricks do not adequately explain the pattern.
