trade

Correct answer: A. They allowed different transactions to be measured on a common basis

Explanation: The governing concept is standardisation in exchange. When buyers and sellers used comparable weights, they could check quantities against a common measure, reducing disputes over under-weighing or over-weighing. Thus option A correctly explains why trust increased. Standard weights did not fix one price for every commodity, eliminate seals completely, or improve the physical quality of goods; they made measurement more reliable.

Correct answer: B. Shared standards were used for trade and measurement

Explanation: The governing concept is standardisation as archaeological evidence of connected exchange. If towns used similar weights, traders and administrators may have relied on a shared system for measuring goods and recording transactions. Therefore, option B is the best conclusion. Absence of contact would not explain matching standards, and options C and D either restrict their function without evidence or contradict the observed similarity.

Correct answer: A. Access to sea routes and resources such as shell

Explanation: The governing concept is the geographical advantage of coastal locations. Coastal Harappan settlements could connect with maritime routes and obtain marine resources such as shell, which were useful for craft production and exchange. Thus option A is correct because it identifies both transport and resource benefits. Coastal sites were not defined only by agricultural land, did not necessarily lie near an overland route to Mesopotamia, and still benefited from reliable measurement.

Correct answer: B. Movement of distant goods became slower or costlier

Explanation: The governing concept is the effect of transport disruption on trade flows. If maritime routes to the Gulf were blocked, long-distance goods would need a slower or more expensive alternative route, or their supply could be reduced. Therefore, option B is correct. Land routes would become more important rather than unnecessary; towns would not automatically become self-sufficient, and measurement standards would remain useful wherever exchange continued.

Correct answer: A. Full-time artisans may not have produced enough food themselves

Explanation: The governing concept is economic interdependence created by occupational specialisation. Full-time bead makers, metalworkers or other artisans devoted much of their labour to craft production, so they may not have grown enough food. Exchange with farming communities supplied grain in return for crafted goods or services. Therefore option A is correct; the other choices confuse food exchange with seal manufacture, metallurgy or ritual donation.

Correct answer: B. Interdependence among producer groups

Explanation: The governing concept is division of labour supported by exchange. Farmers produced food, while specialised urban groups made tools, ornaments or other goods; neither group necessarily supplied everything it needed. Regular movement of food into towns therefore indicates economic interdependence among producers. Option B is correct. Ritual donation might explain some transfers, but isolation and absence of organisation contradict the evidence of sustained supply.

Correct answer: D. Movement, collection and exchange of goods

Explanation: The governing concept is the organisation of exchange across space. Routes enabled goods and people to move; centres could gather, store or redirect materials; and markets brought buyers and sellers together for exchange. Their combined function was therefore movement, collection and exchange, making option D correct. Production, taxation or ritual control might occur in particular contexts, but none alone describes the whole network.

Correct answer: A. A collection and redistribution centre

Explanation: The governing archaeological principle is that the distribution and provenance of objects help infer a settlement’s economic role. Goods from many regions arriving at one town suggest that it collected materials and redistributed them to other users or places. Thus option A is correct. A purely agricultural village, burial site or isolated settlement would not adequately explain the concentration of diverse regional goods, although farming or burial could also occur there.

Correct answer: C. Comparative study of raw-material sources and object distribution

Explanation: The governing concept is archaeological distribution analysis. If a raw material is traced to a particular source and finished or unfinished objects made from it occur at several sites, comparing their locations can indicate the probable direction of movement and possible trade routes. House height, burial counts, or soil colour do not directly reveal exchange pathways. Therefore, option C is the strongest evidence-based choice.

Correct answer: B. Organic material decays over time

Explanation: The governing concept is preservation bias in archaeology: materials survive unequally. Cotton and other organic goods usually decay through moisture, microbes and time, so they may leave little or no archaeological trace. Therefore, limited evidence does not prove that cotton was absent from Harappan exchange. Option A wrongly treats missing remains as proof of no trade, while C and D have no historical basis.

Correct answer: A. Grain from villages and tools from towns

Explanation: Two-way exchange means that each side supplies goods to the other. Villages could provide agricultural produce such as grain, while towns, where specialised crafts were concentrated, could supply tools and other manufactured items. Option A therefore shows mutual economic dependence. B reverses the likely production pattern and is incomplete; C denies exchange, and D wrongly limits trade to foreign goods.

Correct answer: A. It supported non-farming craftspersons and traders

Explanation: The governing economic concept is occupational specialisation. When farming produced more food than cultivators immediately needed, part of the surplus could support craft workers, traders and other urban specialists. Their work made production and exchange more extensive, including over long distances. Option A explains this indirect link; B, C and D contradict the relationship between surplus, specialisation and trade.

Correct answer: A. Regional specialisation and mutual exchange

Explanation: The key concept is regional specialisation: different places concentrate on producing different goods, often because of resources, skills or established workshops. If shells are worked mainly in one region and beads in another, communities would have reasons to exchange their products. Option A follows this evidence. B and C deny the interdependence implied by separate production centres, while D contradicts the stated distribution.

Correct answer: A. Transferring goods between different transport systems

Explanation: A route junction has a strategic economic location because goods can be transferred from river transport to land caravans, or in the reverse direction. Such settlements may collect, store and redistribute commodities, reducing the difficulty of moving them farther. Option A connects location with transport and exchange. B is too narrow, while C and D contradict the likely commercial advantage of being well connected.

Correct answer: A. A planned support system for long-distance transport

Explanation: A connected chain of caravan stops suggests planned infrastructure for repeated movement. Such places could provide water, rest, fodder, protection, storage and opportunities for local exchange, helping people and animals travel long distances. Option A best explains the network’s practical function. B is too limited, while C and D do not account for route-linked staging points. The pattern therefore supports organised trade logistics.

Correct answer: A. They were route stops or local exchange points

Explanation: The governing concept is contextual archaeological interpretation: evidence must be read with its location and associated features. Small stores beside water on a route could support travellers, temporary storage, or local exchange. Therefore option A is the best inference. A cemetery, a natural deposit, or a production ban is not established merely by finding stored goods near water.

Correct answer: A. Production could decline due to raw-material shortages

Explanation: The governing concept is supply-chain dependence in long-distance trade. If maritime routes carrying copper from Oman were interrupted, workshops using that imported metal could receive less raw material, raise prices, or reduce output. Option A follows this causal chain. The other choices describe impossible transformations, an unsupported increase in bead production, or an unrelated effect on weights.

Correct answer: A. A redistribution network based on centres and subcentres

Explanation: The governing concept is spatial hierarchy in exchange networks. A few major centres containing or distributing goods to many smaller sites can represent collection, storage, and redistribution through linked settlements. Option A explains the observed pattern without claiming certainty. Isolation and complete disorganisation contradict the connected distribution, while natural spread does not adequately explain a structured centre-and-site pattern.

Correct answer: A. Possible regional distribution from the centre

Explanation: The governing concept is spatial distribution and regional redistribution. When similar goods are concentrated at a major centre and also appear at nearby smaller sites, movement from the centre or through its network becomes a reasonable possibility. Option A is appropriately cautious because the pattern suggests, rather than proves, redistribution. The other options ignore the spatial relationship or misclassify manufactured goods as natural.

Correct answer: A. Large-scale production and wide distribution of similar goods

Explanation: The governing concept is archaeological evidence for market demand. Repeated large-scale production combined with wide distribution suggests that many users wanted the same goods and that exchange systems regularly supplied them. Option A is therefore strongest. One broken object is too limited, local raw material concerns supply rather than demand, and one unusual item cannot establish a broad market pattern.

Correct answer: A. The object was valuable and used for a long time

Explanation: The governing concept is object biography: use, repair, and reuse reveal how people valued material goods. Repeated repair of a rare imported object implies that replacing it was difficult or costly, so users extended its life. Option A best explains the evidence. Easy availability, unlimited raw material, and independence from trade would make repeated repair less necessary, not more.

Correct answer: A. Recycling of rare imported material

Explanation: The governing concept is resource conservation in craft and exchange systems. Reshaping broken ornaments made from foreign stone shows that artisans or users retained and reused the material instead of discarding it. Option A is correct because recycling commonly reflects scarcity, cost, or high value. It does not show that the material was worthless, that artisans lacked knowledge, or that routes were fully open.

Correct answer: A. Selection of goods with uniform size and finish at an export centre

Explanation: The governing concept is standardisation in organised trade. At an export centre, selecting goods with consistent measurements and finish suggests inspection, grading, or agreed expectations for distant buyers. Option A therefore gives the clearest evidence of quality control. Exporting every defective item, lacking measuring tools, or accepting completely different sizes would weaken consistency rather than demonstrate it.

Correct answer: A. Different quality levels for different markets

Explanation: The governing concept is market segmentation: producers may have made goods of different quality for different consumers. If export items are more carefully finished while local-use items are less refined, the contrast suggests that external markets demanded or rewarded superior workmanship. It does not prove that all local goods were imported, nor does it show an absence of trade. Therefore, option A is the best conclusion.

Correct answer: A. Standardised weights and seals and distribution of distant goods

Explanation: Organised trade does not require coins. Standardised weights suggest agreed methods for measuring quantities, seals may have helped identify consignments or authorities, and the movement of materials over long distances indicates exchange networks. These clues reinforce one another, whereas large houses, figurines, or animal bones alone cannot demonstrate systematic commercial activity. Hence option A is the strongest evidence-based answer.
