Q1:
Consider the following statements regarding the NISAR mission: How many of the above statements are correct?
A: Only two
B: Only three
C: All four
D: Only one
Answer: B
Explanation:
Statements 1, 2, and 4 are correct. NISAR is equipped with dual-band radars: NASA’s L-band and ISRO’s S-band, enabling it to measure minute surface changes, including those related to glaciers, forest cover, and tectonic activity. It will be launched by ISRO using a GSLV rocket. The collaboration showcases India-US partnership in space.
However, Statement 3 is incorrect: NISAR can detect changes as small as one centimeter, not one meter. This high resolution is what makes it a powerful tool in disaster monitoring and climate studies.

Q3:
Consider the following statements: Statement I: The Andhra Pradesh government has approved a reservation framework that classifies Scheduled Castes into groups based on sub-caste-specific backwardness. Which of the following is correct?
Statement II: This framework is based on the idea that all SC sub-castes are equally represented in education, jobs, and political institutions.

B: Both Statement-I and Statement-II are correct, but Statement-II does not explain Statement-I
C: Statement-I is correct, but Statement-II is incorrect
D: Statement-I is incorrect, but Statement-II is correct
Answer: C
Explanation:
Statement I is correct: The Andhra Pradesh ordinance introduces sub-categorization of SCs based on social, educational, and economic backwardness to ensure equitable reservation.
Statement II is incorrect: The move stems from the acknowledgment that all SC sub-castes are not equally represented—some communities have benefited more than others. Hence, the ordinance aims to correct this imbalance, not assume equal representation.
