Q141. Consider the following members of the Constituent Assembly: I. N. Gopalaswamy Ayyangar II. Alladi Krishnaswamy Ayyar III. Dr. K. M. Munshi IV. Syed Mohammad Saadullah Which of the above combination of statements represents members of the Drafting Committee?
Explanation
The Drafting Committee consisted of seven members who were instrumental in shaping the Constitution. These included Dr. B. R. Ambedkar (Chairman), N. Gopalaswamy Ayyangar, Alladi Krishnaswamy Ayyar, Dr. K. M. Munshi, Syed Mohammad Saadullah, N. Madhava Rau (who replaced B. L. Mitter), and T. T. Krishnamachari (who replaced D. P. Khaitan). All four individuals listed in the question were members.
Q142. Consider the following statements regarding the African Plateau: I. Much of the African continent consists of elevated plateau regions. II. The East African Plateau is deeply fragmented by the Great Rift Valley system. III. The plateau region strictly receives snowfall throughout the year due to high latitudes. Which of the above statement(s) is/are incorrect?
Explanation
Much of Africa consists of high plateaus, with the East African Plateau being notably dissected by the Great Rift Valley. While these areas are elevated, they are primarily located in tropical and subtropical latitudes. Therefore, they do not receive snowfall throughout the year, except on the very highest mountain peaks. This distinguishes the plateau’s general climate from high-latitude polar regions.

Q143. Consider the following statements regarding the role of labor in economic growth: I. Human capital formation through education and health improves labor productivity. II. An expanding working-age population automatically guarantees economic growth regardless of job creation. III. The demographic dividend requires supportive economic policies to be realized. Which of the above statement(s) is/are correct?
Explanation
Human capital formation through education and health is essential for improving labor productivity and driving economic growth. While an expanding working-age population provides a potential demographic dividend, this growth is not automatic. It requires supportive economic policies and job creation to be realized. Without these conditions, a large population can become a burden rather than an asset for the national economy.

Q144. When an object undergoes free fall near the Earth’s surface (ignoring air resistance), its:
Explanation
During free fall in a vacuum near the Earth’s surface, all objects experience a constant acceleration due to gravity, approximately 9.8 meters per second squared. While the velocity of the falling object increases uniformly over time, the rate at which it speeds up remains the same. Air resistance is ignored in this idealized model to focus on pure gravitational influence on motion.

Q145. Evidence of Upper Palaeolithic culture in Rajasthan has been most prominently identified in and around which basin?
Explanation
Evidence of Upper Palaeolithic culture in Rajasthan is most prominently found in the Pushkar basin, particularly around the Budha Pushkar lake. This region has yielded sophisticated stone tool assemblages, including blades and burins. The environmental context suggests that these groups inhabited the area during a period of fluctuating aridity, utilizing the lake’s resources while developing more efficient and specialized technologies.

Q146. Which of the following statements about Harappan pottery is incorrect?
Explanation
Harappan pottery was predominantly utilitarian and mass-produced using the potter’s wheel. The most characteristic type was red ware, often decorated with black painted designs featuring motifs like pipal leaves and intersecting circles. While polychrome or multi-colored pottery was produced, it was quite rare and not a common feature found in the majority of households across the different settlements.

Q147. Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Dr. B. R. Ambedkar is recognized as the Father of the Constitution of India. Reason (R): He was the Chairman of the Drafting Committee and successfully piloted the draft Constitution through the Constituent Assembly.
Explanation
Dr. B. R. Ambedkar is widely hailed as the Father of the Constitution of India due to his contribution to its creation. As Chairman of the Drafting Committee, he was responsible for synthesizing diverse viewpoints and meticulously drafting legal provisions. His expert handling of debates in the Constituent Assembly ensured the successful adoption of the final constitutional document by the assembly.
Q148. Identify the odd one out among the following regions based on their dominant landform classification as plateaus.
Explanation
The Anatolian Plateau, Katanga Plateau, and Colorado Plateau are all distinct elevated flatlands characterized by their high altitude and relatively level surfaces. In contrast, the Amazon Basin is a massive low-lying alluvial plain formed by river deposition. This fundamental difference in topographic classification and elevation makes the Amazon region the odd one out when compared to the other mentioned plateaus.

Q149. Match List I with List II and select the correct answer using the codes given below:
Factors of Growth
Examples/Mechanisms
A. Human Capital
i. Implementation of property rights and rule of law
B. Physical Capital
ii. Invention of a new efficient manufacturing process
C. Technology
iii. Construction of highways and telecommunication networks
D. Institutional Factors
iv. Investment in technical training and public health
Explanation
Economic growth is driven by a combination of diverse factors. Human capital is developed through training and public health initiatives. Physical capital involves building tangible infrastructure like highways. Technological progress stems from inventing more efficient manufacturing processes. Finally, institutional factors like the rule of law and property rights create the stable environment necessary for investment and long-term economic prosperity.

Q150. The minimum initial velocity required for an object to escape the Earth’s gravitational pull is approximately:
Explanation
Escape velocity is the minimum speed an object must reach to break free from a planet’s gravitational field without further propulsion. For Earth, this value is approximately 11.2 kilometers per second. If an object is launched at this speed, its kinetic energy will exactly balance its gravitational potential energy, allowing it to move infinitely far away from the Earth’s pull.
