| Theory of Decline | Proponent Scholar |
|---|---|
| A. Aryan Invasion | i. H.T. Lambrick |
| B. Ecological Imbalance | ii. Mortimer Wheeler |

Various scholars have proposed theories for the decline of the Harappan civilization. Mortimer Wheeler suggested an Aryan invasion based on skeletal remains. Fairservis emphasized ecological imbalance due to resource depletion. Robert Raikes proposed tectonic disturbances causing floods, while H.T. Lambrick suggested that the shifting of the Indus River course deprived the cities of their essential water source and transport.
Q123. Given below are two statements regarding the dual functions of the Constituent Assembly:
Statement I: The Constituent Assembly became the first Parliament of free India (Dominion Legislature).
Statement II: Whenever the Assembly met as the Constituent body it was chaired by Dr. Rajendra Prasad, and when it met as the legislative body, it was chaired by G. V. Mavalankar.
Identify the correct option:
Statement I: The Constituent Assembly became the first Parliament of free India (Dominion Legislature).
Statement II: Whenever the Assembly met as the Constituent body it was chaired by Dr. Rajendra Prasad, and when it met as the legislative body, it was chaired by G. V. Mavalankar.
Identify the correct option:
Explanation
Under the Indian Independence Act of 1947, the Constituent Assembly was empowered to perform two distinct roles: framing the Constitution and enacting ordinary laws. It thus became the first Parliament of free India. When performing constitutional tasks, Dr. Rajendra Prasad presided, but when functioning as a legislative body to pass laws, G. V. Mavalankar took the chair as Speaker.
Q124. The Brazilian Plateau is renowned globally for the extensive reserves of which of the following minerals?
Explanation
The Brazilian Plateau, a vast upland region in South America, is geologically ancient and highly stable. It is world-renowned for its immense mineral wealth, particularly its massive reserves of high-grade iron ore and manganese. These resources are foundational to Brazil’s industrial economy and its role as a global exporter. The plateau also contains significant deposits of gold, diamonds, and bauxite.
Q125. In the context of factors determining economic growth, physical capital accumulation leads to economic growth primarily by:
Explanation
Physical capital accumulation involves increasing the stock of machinery, equipment, and infrastructure used in production. This process drives economic growth by enhancing the productive capacity of the economy. Better tools and technology allow workers to produce more output per hour, leading to higher total national income. Consequently, investment in physical capital is a fundamental requirement for sustained industrial expansion.
Q126. According to the universal law of gravitation, the force between two objects is inversely proportional to:
Explanation
The universal law of gravitation describes the attractive force between two masses. It states that this force is directly proportional to the product of the masses and inversely proportional to the square of the distance between their centers. This inverse-square relationship means that as the distance between objects increases, the gravitational pull weakens significantly, following a predictable and precise mathematical pattern.
Q127. Which of the following correctly describes the archaeological characteristics of the Wagan river basin in Rajasthan?
Explanation
The Wagan river basin in Rajasthan is archaeologically significant for its evidence of early human occupation. Systematic surveys have revealed a rich sequence of artifacts, spanning the Acheulian tradition of the Lower Palaeolithic to various Middle Palaeolithic flake tools. These findings indicate that the basin provided a stable environment with accessible raw materials and water, supporting human populations over long periods.
Q128. What was the most critical factor that facilitated the extensive internal and external trade networks of the Indus Valley Civilisation?
Explanation
The extensive internal and external trade of the Indus Valley Civilisation was primarily fueled by an agricultural surplus and highly specialized craft production. Farmers produced enough food to support non-agricultural specialists like potters, bead-makers, and metallurgists. This economic foundation allowed for the export of finished goods and the import of raw materials, sustaining a prosperous and interconnected urban network.
Q129. Which of the following statements is correct regarding the working of the Constituent Assembly?
Explanation
The Indian Independence Act of 1947 transformed the Constituent Assembly into a fully sovereign body, allowing it to abrogate or alter any law made by the British Parliament in relation to India. While the Muslim League initially boycotted the meetings and princely states joined gradually, this legal sovereignty was the defining feature that empowered the assembly to draft an independent constitution.
Q130. Match List-I (Plateau Name) with List-II (Type of Plateau) and select the correct answer using the codes given below:
| Plateau Name | Type of Plateau |
|---|---|
| A. Tibetan Plateau | i. Continental Plateau |
| B. Deccan Plateau | ii. Piedmont Plateau |
| C. Patagonian Plateau | iii. Volcanic Plateau |
| D. Antarctic Plateau | iv. Intermontane Plateau |
Explanation
Plateaus are classified by their geological setting and origin. The Tibetan Plateau is intermontane, surrounded by mountains. The Deccan Plateau is volcanic, formed by lava flows. The Patagonian Plateau is a piedmont type, located at the foot of the Andes. The Antarctic Plateau is a continental plateau, representing a massive elevated shield. These categories help geographers understand the diverse history of landforms.Answer key for these questions
