Test your knowledge with today's UPSC Prelims practice questions derived from today's top newspaper editorials. Attempt each question before reading the explanation and trap alerts.

Question 1: India, BRICS, and West Asian Geopolitics

Context: With the expansion of the BRICS grouping and the evolving geopolitical landscape in West Asia, consider the following statements:

Article 51 of the Indian Constitution, under the Directive Principles of State Policy, mandates that the State shall endeavor to foster respect for international law and treaty obligations.
BRICS expansion has been formally codified through a "membership treaty" that automatically binds member states to a collective security pact in the event of external aggression.
India’s approach to West Asia within the BRICS framework emphasizes 'strategic autonomy' over bloc-based alignment.

Which of the statements given above is/are correct?

(a) 1 and 2 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2 and 3

👉 Click to Reveal Answer & Detailed Explanation

Correct Answer: (c) 1 and 3 only

Detailed Explanation: Statement 1 is correct; Article 51 explicitly directs the State to promote international peace and security. Statement 2 is incorrect; BRICS is a multilateral forum for cooperation, not a military alliance; it has no collective security pact or 'membership treaty' akin to NATO's Article 5. Statement 3 is correct; India consistently maintains a policy of multi-alignment and strategic autonomy, ensuring that its engagement with West Asian nations (like Iran, UAE, Saudi Arabia) is not compromised by bloc-based constraints.

⚠️ UPSC Prelims Trap Alert: UPSC often conflates economic forums (BRICS, G20, SCO) with military alliances (NATO, AUKUS). Always remember BRICS is non-military.

Syllabus Match: GS Paper 2 - International Relations; Constitutional Provisions.

Question 2: Outer Space Governance and Weaponization

Context: Regarding the debate on 'on-orbit space control weapons' and international space law, consider the following:

The 1967 Outer Space Treaty (OST) explicitly prohibits the stationing of weapons of mass destruction (WMDs) in orbit, but it does not explicitly ban conventional weapons.
The concept of "Peaceful uses of outer space" under international law implies the complete demilitarization of space, including the use of military satellites for reconnaissance.
India is a signatory to the Outer Space Treaty.

Which of the statements given above is/are correct?

(a) 1 and 2 only
(b) 1 and 3 only
(c) 2 and 3 only
(d) 1, 2 and 3

👉 Click to Reveal Answer & Detailed Explanation

Correct Answer: (b) 1 and 3 only

Detailed Explanation: Statement 1 is correct; the OST prohibits WMDs but contains loopholes regarding conventional weapons. Statement 2 is incorrect; "Peaceful uses" does not mean non-military; military satellites for communication, navigation, and reconnaissance are widely accepted and practiced by all spacefaring nations. Statement 3 is correct; India is a signatory to the OST.

⚠️ UPSC Prelims Trap Alert: Candidates often assume "peaceful uses" means "no military activity." International law distinguishes between "weaponization" (placing weapons) and "militarization" (using military assets).

Syllabus Match: GS Paper 3 - Space Technology; International Treaties.

Question 3: Excess Liquidity and Banking Operations

Context: With the RBI managing excess liquidity in the banking system, consider the following statements:

The Standing Deposit Facility (SDF) allows the RBI to absorb liquidity from banks without providing government securities as collateral.
The Reverse Repo rate is currently the primary tool used by the RBI to absorb liquidity from the banking system.
Excess liquidity in the banking system can lead to demand-pull inflation if not sterilized by the central bank.

Which of the statements given above is/are correct?

(a) 1 and 2 only
(b) 1 and 3 only
(c) 2 and 3 only
(d) 1, 2 and 3

👉 Click to Reveal Answer & Detailed Explanation

Correct Answer: (b) 1 and 3 only

Detailed Explanation: Statement 1 is correct; SDF was introduced in 2022 to remove the requirement of collateral for absorbing liquidity, making it more flexible. Statement 2 is incorrect; while Reverse Repo exists, the SDF has effectively replaced it as the primary tool for liquidity absorption. Statement 3 is correct; excess money supply typically lowers interest rates, increasing consumption and potentially driving demand-pull inflation.

⚠️ UPSC Prelims Trap Alert: Do not confuse SDF with Reverse Repo. SDF is collateral-free; Reverse Repo requires the RBI to provide collateral (G-secs).

Syllabus Match: GS Paper 3 - Indian Economy (Banking/Monetary Policy).

Question 4: Carbon Credits Trading Scheme (CCTS)

Context: Regarding the Carbon Credits Trading Scheme (CCTS) in India, consider the following statements:

The CCTS is notified under the Energy Conservation (Amendment) Act, 2022.
The Bureau of Energy Efficiency (BEE) acts as the administrator for the Indian Carbon Market (ICM).
The scheme allows for both a compliance mechanism and a voluntary mechanism for carbon trading.

Which of the statements given above is/are correct?

(a) 1 and 2 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2 and 3

👉 Click to Reveal Answer & Detailed Explanation

Correct Answer: (d) 1, 2 and 3

Detailed Explanation: All statements are correct. The 2022 Amendment empowered the government to establish a carbon market. The BEE is the designated agency to develop standards, and the framework supports both mandatory compliance (for energy-intensive sectors) and voluntary participation.

⚠️ UPSC Prelims Trap Alert: Watch out for the Ministry involved—it is the Ministry of Power, not the Ministry of Environment, Forest and Climate Change (MoEFCC), though they work in coordination.

Syllabus Match: GS Paper 3 - Environment & Economy.

Question 5: Urbanization and Migration Patterns

Context: With rapid urbanization and shifting global migration patterns, consider the following:

'Push factors' refer to the negative conditions (e.g., poverty, famine) that force people to leave their origin, while 'pull factors' refer to the perceived advantages (e.g., jobs, services) of the destination.
In the context of India, the feminization of migration is a growing trend, where women migrate primarily for economic reasons rather than marriage.
Sustainable Development Goal (SDG) 11 specifically targets the creation of inclusive, safe, resilient, and sustainable cities.

Which of the statements given above is/are correct?

(a) 1 and 2 only
(b) 1 and 3 only
(c) 2 and 3 only
(d) 1, 2 and 3

👉 Click to Reveal Answer & Detailed Explanation

Correct Answer: (b) 1 and 3 only

Detailed Explanation: Statement 1 is the classic definition of Lee’s Migration Theory. Statement 2 is incorrect; while women's migration is increasing, data (Census/NSSO) consistently shows that marriage remains the primary reason for female migration in India, not independent economic migration (unlike male migration).

⚠️ UPSC Prelims Trap Alert: UPSC tests the "reason" for migration. Always distinguish between male migration (economic) and female migration (marriage-led) in the Indian context.

Syllabus Match: GS Paper 1 - Urbanization/Society.
