Harappan archaeology

Correct answer: A. Direct information about rulers and administration

Explanation: Since scholars cannot yet read the Harappan script, they lack direct written accounts of rulers, offices, laws and administrative institutions. Archaeology can still reveal brick dimensions, drain construction and the locations of settlements through physical remains, plans and excavation. Those material features do not depend on deciphering texts. Therefore option A identifies the type of knowledge that remains especially limited, while the other options are accessible archaeologically.

Correct answer: A. Diet and animal husbandry

Explanation: Animal bones are bioarchaeological evidence. Their species, age, cut marks and signs of domestication can help historians reconstruct what people ate, which animals they hunted, and which they kept for food or work. Thus option A is correct because bones provide evidence about diet and animal husbandry. They cannot directly reveal the language of the script, a list of kings or the orientation of streets, so options B, C and D are unsuitable.

Correct answer: A. Agriculture and food supply

Explanation: The governing concept is the use of plant remains to reconstruct an ancient economy. Identifying grains and their quantities can indicate which crops were cultivated, what people consumed, and how agricultural production supported urban populations. Therefore, option A is correct. Grain remains do not directly reveal military organisation, the direction of writing or palace decoration, making options B, C and D unrelated to this evidence.

Correct answer: A. The form of political authority is unclear

Explanation: The governing concept is careful interpretation of archaeological evidence. Since no clearly identified massive palace has been found, historians cannot confidently describe how political authority was organised. This supports option A, not the stronger claims that there were no rulers or that everyone was equal. Option D is also unsupported: urban planning and public works may indicate administration even without a known palace.

Correct answer: B. Public or community activities

Explanation: Large buildings at Mohenjodaro suggest that some spaces were designed for activities involving groups rather than only individual households. Their scale and placement may indicate public or community use, so option B is the most reasonable interpretation. Archaeologists remain cautious because the undeciphered script and limited contextual evidence prevent certainty about every building’s exact function. The other choices contradict the urban setting or provide no valid inference.

Correct answer: A. Organised contact among different regions

Explanation: The governing concept is standardisation as evidence of interaction and shared practices. Similar weights, brick proportions, seals, and other material conventions across distant settlements suggest that people, ideas, goods, or administrative practices moved between regions. Such similarities are inconsistent with complete isolation, and they do not specifically prove only religious travel or an absence of agriculture. Hence option A gives the broadest and most defensible interpretation.

Correct answer: A. Childhood and recreation

Explanation: The governing concept is the use of everyday artefacts as evidence for social history. Clay toys can reveal children’s play, recreation and aspects of ordinary domestic life, making option A the best answer. They do not directly decode the script, record agricultural tax, or prove political administration. Like all artefacts, toys provide clues that must be interpreted alongside other archaeological evidence.

Correct answer: A. A terracotta whistle or rattle

Explanation: The governing idea is that artefacts can provide cautious clues about cultural and recreational practices. A terracotta whistle or rattle could have produced sound and may therefore indicate music, play or entertainment, so option A is correct. A standardised weight points more toward measurement and exchange, a brick drain toward sanitation, and a grain seed toward agriculture or diet. The interpretation remains probable rather than certain.

Correct answer: A. Raised platforms and rebuilding

Explanation: The governing concept is urban adaptation to environmental hazards. In flood-prone areas, raising buildings or constructing on elevated platforms could reduce the effects of standing water, while rebuilding after damage could restore usable structures. Archaeology supports this as a probable response rather than a universally proven single policy. Closing every well would remove an important water source, and stopping trade or abandoning agriculture would not directly control floods. Thus option A is the best answer.

Correct answer: A. In different building materials and water-management methods

Explanation: The governing concept is the coexistence of cultural integration and regional variation. Harappan sites share features such as standardised bricks and planning, yet local geology, climate and water availability influenced construction materials, wells, drains, reservoirs and other water arrangements. This explains how cities could show broad uniformity without being identical. The other choices are incorrect: Harappan writing was present at many sites, trade existed, and the cities did not all have a circular plan.

Correct answer: A. Identification of crops grown and consumed

Explanation: Charring can preserve plant remains, allowing researchers to identify grains and other crops recovered from archaeological layers. This evidence helps reconstruct cultivation, food consumption, storage, and aspects of the urban agricultural economy, so option A is correct. Charred grains cannot provide rulers' genealogies, wall measurements, or the pronunciation of an undeciphered script; those require different kinds of evidence.

Correct answer: B. Long-distance trade relations

Explanation: The governing archaeological concept is that objects found outside their production region can reveal interregional contact. Harappan beads in Mesopotamia were transported across a considerable distance, indicating exchange or trade relations between the two regions. Their presence does not prove only local production, agricultural absence or script translation. Hence option B is the correct conclusion.

Correct answer: C. One where tools, raw materials and production debris are found

Explanation: A craft-oriented settlement is identified through archaeological evidence of production rather than residence alone. Tools, raw materials, unfinished objects and manufacturing waste together reveal that activities such as bead-making, pottery or metalworking took place there. Agricultural fields suggest farming, houses and hearths suggest habitation, and graves indicate burial practices. Thus option C provides the strongest evidence for a craft-production centre.

Correct answer: D. A relatively later period

Explanation: The governing concept is archaeological stratigraphy. In a normally undisturbed site, deposits accumulate over time, so later construction, occupation, repairs, and discarded objects tend to lie above earlier deposits. The upper layer therefore generally belongs to a relatively later period, making option D correct. It is not necessarily the latest or modern layer, and it is certainly not always pre-Harappan. Disturbance can alter the sequence, so archaeologists examine context carefully.

Correct answer: B. Radiocarbon dating

Explanation: The governing concept is scientific dating. Radiocarbon dating measures the decay of carbon-14 in once-living organic material, such as charcoal or bone, to estimate when it was formed or deposited. It therefore helps establish the chronology of archaeological sites, within method-specific limits. Option B is correct; oral traditions, folk songs and linguistic comparison may provide historical clues but are not this dating technique.

Correct answer: C. The script is undeciphered and meanings of motifs are uncertain

Explanation: Historical interpretation must account for the limits of evidence. Harappan seals contain animal motifs, but the associated script remains undeciphered, and an image may have had administrative, religious, symbolic, or other meanings. Historians therefore compare context and patterns rather than treating one interpretation as certain. The seals are not modern, and the animals were not necessarily imaginary. Option C is correct.

Correct answer: A. It is not always possible to study every object from a large site

Explanation: Archaeological sites may contain enormous quantities of artefacts, soil samples and structural remains, while time, funding and conservation facilities are limited. Sampling selects material that can represent wider deposits or activity areas, making systematic study possible. A sound sample must be recorded carefully, but it does not eliminate excavation or stop dating. Option A is correct.

Correct answer: C. Economic or social differences may have existed

Explanation: The governing archaeological method is cautious inference from settlement remains. Differences in house size, layout or facilities may reflect variation in wealth, household composition, occupation or social position. Thus option C is the best answer, although it should be stated as a possibility rather than absolute proof. Unequal houses do not prove the absence of planning or that every structure was religious.

Correct answer: A. Construction technology and durable architecture

Explanation: Baked bricks require shaping, drying and controlled firing, so their widespread use reflects knowledge of construction technology and the ability to produce durable building materials. Option A is therefore correct. The evidence does not prove a definite shortage of wood, because several materials could have been used together. Nor does it show that bricks were exclusively religious or that agriculture was absent.

Correct answer: A. It helps explain possible use and accessibility of the building

Explanation: The location, width and direction of an entrance reveal how people approached and moved through a structure. A broad or public route may suggest communal access, while a narrow or controlled entrance may indicate restricted or specialised use. Option A is correct because access patterns help interpret building function. Entrance routes do not determine brick colour, decipher an undeciphered script or measure river depth.
