Q162. Astronauts in low Earth orbit experience "weightlessness" because:
Explanation
Astronauts in orbit experience weightlessness not because gravity is absent, but because they and their spacecraft are in a state of continuous free fall towards Earth. As they move forward at high speed, the planet’s surface curves away at the same rate they fall. This creates an environment where no normal force acts between the astronauts and their surroundings.
Q163. Consider the following statements regarding the Upper Palaeolithic phase in Rajasthan:
I. The climate during this phase in western Rajasthan was highly humid and tropical.
II. Burins and retouched blades represent the hallmark tool types of this era.
III. Ostrich eggshells have been discovered at some sites indicating prevailing environmental conditions.
Which of the above statement(s) is/are correct?
I. The climate during this phase in western Rajasthan was highly humid and tropical.
II. Burins and retouched blades represent the hallmark tool types of this era.
III. Ostrich eggshells have been discovered at some sites indicating prevailing environmental conditions.
Which of the above statement(s) is/are correct?
Explanation
The Upper Palaeolithic phase in Rajasthan is characterized by the production of specialized tools like burins and retouched blades. Discoveries of ostrich eggshells at several sites indicate that the environment was quite arid rather than humid or tropical. These eggshells were often used to create beads, providing evidence of early artistic expression and human adaptation to the harsh environment.
Q164. The discovery of numerous terracotta female figurines with elaborate headdresses in the Indus Valley heavily implies the existence of which religious phenomenon?
Explanation
The discovery of numerous terracotta female figurines, often heavily adorned with jewelry and elaborate headdresses, is a significant feature of Harappan archaeology. These figurines are widely interpreted by scholars as representations of a Mother Goddess. This suggests that the worship of a female deity associated with fertility and creation was a widespread and integral aspect of Harappan religious life.
Q165. Which of the following statements accurately describes the readings of the Draft Constitution in the Constituent Assembly?
Explanation
The drafting process involved three formal readings. The first reading was a general discussion in 1948. The second reading involved a detailed, clause-by-clause consideration where thousands of amendments were proposed. The third reading began in November 1949 and ended on November 26, 1949, when the motion for the adoption of the Constitution was finally passed and signed.
Q166. Consider the following statements regarding major world plateaus:
I. The Patagonian plateau is an example of a piedmont plateau.
II. The Deccan plateau slopes generally from east to west.
III. The Tibetan plateau is known as the "Roof of the World".
IV. The Brazilian plateau occupies a large portion of eastern South America.
Which of the above statement(s) is/are correct?
I. The Patagonian plateau is an example of a piedmont plateau.
II. The Deccan plateau slopes generally from east to west.
III. The Tibetan plateau is known as the "Roof of the World".
IV. The Brazilian plateau occupies a large portion of eastern South America.
Which of the above statement(s) is/are correct?
Explanation
The Patagonian Plateau is a piedmont plateau located at the foot of mountains. The Tibetan Plateau is globally recognized as the "Roof of the World" due to its extreme altitude. The Brazilian Plateau covers much of eastern South America. However, the Deccan Plateau generally slopes from west to east, which is why most of its major rivers flow toward the Bay of Bengal.
Q167. Which of the following is a primary characteristic of the "Pre-conditions for take-off" stage in the economic growth model?
Explanation
The pre-conditions for take-off involve the initial transition from a traditional society. During this stage, a new class of entrepreneurs emerges, and investment in social overhead capital, such as transport and infrastructure, begins to increase. While agriculture remains dominant, the foundations for industrialization are laid. This phase is necessary to prepare the economy for the rapid growth seen in later stages.
Q168. Consider the following planets:
I. Jupiter
II. Mars
III. Earth
Which of the following represents the correct arrangement of these planets in increasing order of their surface gravity?
I. Jupiter
II. Mars
III. Earth
Which of the following represents the correct arrangement of these planets in increasing order of their surface gravity?
Explanation
Surface gravity depends on a planet’s mass and radius. Mars has a lower mass than Earth, resulting in weaker gravitational pull. Jupiter, being the most massive planet in the solar system, possesses the strongest surface gravity among the three. Therefore, the correct sequence from the weakest to the strongest gravitational force is Mars, followed by Earth, and then Jupiter as the highest.
Q169. Which of the following stands as an odd one out among the Upper Palaeolithic/Mesolithic sites of the Thar region?
Explanation
Budha Pushkar, Hokra, and Jayal are significant prehistoric sites within the Thar region, yielding Palaeolithic or Mesolithic evidence. In contrast, Gilund is a major Chalcolithic site located in the Banas river basin of southeastern Rajasthan. It belongs to the Ahar culture and is characterized by a much later agricultural economy, sophisticated pottery, and the use of copper and brick architecture.
Q170. Consider the following statements about Harappan trade mechanisms:
I. Trade was heavily reliant on the barter system.
II. Weights were usually made of chert and followed a binary system in the lower denominations.
III. Metal money and minted coins were the primary mediums of exchange.
IV. Seals were widely used to stamp clay tags on bales of goods for authentication.
Which of the combination of statements given above is correct?
I. Trade was heavily reliant on the barter system.
II. Weights were usually made of chert and followed a binary system in the lower denominations.
III. Metal money and minted coins were the primary mediums of exchange.
IV. Seals were widely used to stamp clay tags on bales of goods for authentication.
Which of the combination of statements given above is correct?
Explanation
Harappan trade relied on a sophisticated system of weights and measures, using chert weights that followed a binary system for lower values. Since no minted coins have been discovered, trade was likely conducted through a barter system. Seals were essential for this process, used to create impressions on clay tags attached to trade goods to ensure their authenticity.Answer key for these questions
