trade

Correct answer: A. Decline in long-distance trade

Explanation: The governing concept is the relationship between exchange networks and urban specialisation. Large Harappan centres supported specialised crafts and complex distribution partly through connections over considerable distances. If those trade networks weakened after about 1900 BCE, access to raw materials, markets and surplus circulation could decline, making large urban centres less viable. This is a probable explanation, not a single proven cause. The other options would not logically explain urban contraction and are unsupported.

Correct answer: A. Identification and security control of goods

Explanation: The governing concept is archaeological inference: an object’s use can be proposed from the context in which it is found. A seal impression on a package could identify its owner, sender, contents, or destination and could show whether the package had been opened. That makes identification and security control the strongest conclusion. Irrigation, burial, and foundation strengthening do not explain impressions on trade goods, so option A is correct.

Correct answer: A. Disagreement and fraud in measurement

Explanation: The governing concept is standardisation: a shared system of weights allowed traders to measure and compare quantities consistently. This reduced disputes over the amount of grain, beads, metals, or other goods and made deliberate under-measurement more difficult. Therefore, disagreement and fraud in measurement is correct. Water shortage, agricultural production, and fortification are unrelated to the direct economic purpose of standard weights.

Correct answer: A. To understand trade and identification of goods

Explanation: Seal impressions are archaeological evidence connected with the marking, ownership or identification of goods and sometimes with the movement of packages. Their signs, designs, material and find context can illuminate exchange practices. Option A is correct; a seal impression does not measure farmland, bake soil or redirect a river.

Correct answer: B. As a source of copper

Explanation: The governing concept is the role of interregional trade in supplying materials for craft production. Archaeological and compositional evidence connects Oman with copper, a metal needed for tools and objects, and indicates exchange between Oman and the Harappan region. Therefore, option B is correct. Gold, timber, and cotton are not the specific material for which Oman is highlighted in this context.

Correct answer: A. Mesopotamia

Explanation: Mesopotamian cuneiform records refer to a place called Meluhha, which historians commonly associate with the Harappan region or its wider cultural sphere. This interpretation is supported by evidence of contacts and exchange between the Indus region and Mesopotamia. Egypt, China and Rome are not the civilisation connected with the Meluhha reference, so option A is correct.

Correct answer: C. Organised trade and transport

Explanation: The governing concept is the connection between craft production and supply networks. If raw materials came from distant places, communities needed dependable contacts, exchange arrangements, carriers and routes to move them to workshops. Household labour, religious rituals and rainfall alone could not secure or transport such materials. Therefore organised trade and transport, option C, is the logical answer.

Correct answer: C. Extensive trade contacts existed

Explanation: When Harappan craft objects or characteristic materials are found far from their production centres, their distribution indicates movement through exchange, transport or networks of contact. The evidence therefore supports extensive trade contacts rather than isolation or only local exchange. The objects’ distant presence also shows that they had value or purpose; it does not suggest that they were useless. Thus, option C is correct.

Correct answer: D. Interregional trade

Explanation: Harappan-style objects found in Mesopotamia demonstrate that goods, designs or cultural products moved between the Indus region and Mesopotamia. Such archaeological distribution is evidence of long-distance contacts and interregional trade, even though it does not by itself reveal every detail of the exchange. It cannot prove an agricultural crisis, complete decipherment of the script or local isolation. Therefore, option D is correct.

Correct answer: A. A long-distance trade network

Explanation: The governing concept is long-distance exchange of raw materials. Lapis lazuli was not generally available at Harappan settlements and had to be obtained from distant regions such as Afghanistan. Moving it required routes, exchange arrangements and links between communities. Therefore, option A is correct. A local market alone could not bring a distant mineral, while marine farming and iron ploughs are unrelated to acquiring this stone.

Correct answer: C. Overseas trade contacts existed

Explanation: The governing concept is archaeological inference from the geographical origin of raw materials. If copper associated with Harappan contexts came from Oman, the material had travelled across a considerable distance, probably through maritime or wider exchange networks. This supports option C, the existence of overseas trade contacts. The evidence contradicts dependence only on local resources, and it does not suggest that craft production or urban metal use was absent.

Correct answer: A. A stable exchange network

Explanation: The governing concept is the organisation of long-distance exchange. A regular flow of raw material from far away implies dependable contacts, transport arrangements, and repeated transactions between source and production centres. Hence a stable exchange network is correct. Town isolation would prevent such supply, while absence of production and agricultural crisis do not logically explain repeated deliveries to craft centres.

Correct answer: B. Moving heavy goods relatively easily

Explanation: The governing concept is the relationship between geography and transport costs. Boats and river routes could move heavy or bulky raw materials more efficiently than carrying them entirely over land, although navigation depended on local conditions. Thus option B is correct. Destroying goods, producing shells, or transforming metal into clay is unrelated to the transport advantage of rivers.

Correct answer: C. Imported materials and exports became easier

Explanation: The governing concept is the connection between ports, trade, and craft production. A craft centre near a port could receive raw materials or specialised goods from other regions and send finished products to distant buyers through established routes. Therefore option C is correct. Such a location would not end farming, drive away craftspersons, or make kilns useless; it would support production and exchange.

Correct answer: D. An organised network of transport, exchange and supply

Explanation: The governing concept is long-distance trade and resource procurement. Copper and lapis lazuli were not available everywhere, so Harappan craft production depended on obtaining raw materials from distant regions. This required routes, transport, exchange relationships, and some coordination of supply. Option D is therefore correct. Local farming could support settlements but could not provide these minerals; ritual travel alone and an absence of organisation do not explain their regular acquisition.

Correct answer: A. Agricultural surplus and craft goods

Explanation: The governing concept is the relationship between production and exchange. Surplus agricultural products could support towns and be exchanged, while specialised craft goods such as beads and pottery circulated among settlements and regions. Therefore option A is correct. Religious texts, military campaigns, and hunting alone do not explain the material basis of a sustained Harappan trading system.

Correct answer: B. For accurate measurement of goods

Explanation: The governing concept is standardisation in economic exchange. Weights made according to an accepted system allowed traders to measure quantities consistently, compare goods, and reduce disputes during transactions. Thus option B is correct. They were not primarily objects for worship or decoration, and they were not writing instruments; their function was practical measurement in trade.

Correct answer: C. Harappan objects found in distant regions

Explanation: The governing archaeological concept is distribution evidence: when recognisably Harappan objects are found in distant regions, their movement indicates contact and probably exchange. Therefore, option C is the most direct evidence of trade links. House numbers, drain width, and field traces can reveal settlement planning or agriculture, but they do not directly demonstrate long-distance commercial connections.

Correct answer: D. Meluhha

Explanation: The historical concept is the use of external written records to identify trading partners. Mesopotamian texts refer to a land called Meluhha, which historians generally associate with the Harappan region. Thus option D is correct. Dilmun is usually linked with Bahrain and the Gulf, Magan with the Oman region, and Akkad with a Mesopotamian political-cultural area.

Correct answer: A. It was a centre linked with maritime contact and trade

Explanation: The governing concept is the role of strategically located settlements in exchange networks. Lothal, situated in present-day Gujarat and associated with maritime connections, supported the movement of goods and craft products. Hence option A is correct. The words “only” make the other choices incorrect because Lothal was not restricted to a hill fort, farming village, or ritual function.

Correct answer: B. Khetri

Explanation: The relevant trade principle is the movement of raw materials from resource zones to craft-producing settlements. The Khetri region of Rajasthan is recognised as a probable source of copper used by Harappan communities. Therefore, option B is correct. Jaisalmer, Mount Abu, and Bharatpur are not the standard Rajasthan association for the copper source tested in this question.

Correct answer: C. Copper

Explanation: The governing idea is that archaeological and textual evidence can connect a trading region with a particular raw material. Harappan contacts with Oman are especially associated with obtaining copper, so option C is correct. Gold and silver are precious metals but are not the standard Oman link in this context, while iron was not a characteristic Harappan trade metal because widespread iron use came later.

Correct answer: D. Afghanistan

Explanation: The governing concept is long-distance procurement of specialised raw materials. Lapis lazuli, a valued blue stone used for ornaments and craft objects, was obtained mainly from the Badakhshan region of present-day Afghanistan. Therefore, option D is correct. Gujarat and Rajasthan were important areas within the Harappan world, but they were not the principal source of this stone; South India is also not the standard source identified here.

Correct answer: C. Sealing and authenticating a package or container

Explanation: The governing archaeological concept is functional interpretation: an artefact is understood by examining how it could have been used. A clay sealing could close a package or container and preserve an identifying impression, helping protect goods and indicate authentication. Therefore, option C is correct. It does not directly represent irrigation, metal smelting, or merely ritual painting, although seals could also carry symbolic imagery.

Correct answer: A. Shared economic standards existed

Explanation: The governing concept is economic standardisation across connected settlements. If similar weights are found in many Harappan towns, people likely used shared measurement conventions, which would make exchange and accounting easier across regions. Therefore, option A is correct. The discovery does not suggest separate systems, absence of trade, or toy use; instead, it points to coordination and interaction within the wider Harappan network.
