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: BRICS and Constitutional Treaty Making

Context: Consider the following statements regarding India's engagement in BRICS and the domestic implementation of international commitments:

Under Article 253 of the Indian Constitution, Parliament has the power to make any law for the whole or any part of the territory of India for implementing any treaty, agreement, or convention with any other country.
The BRICS expansion to include West Asian nations does not require parliamentary ratification for India to participate in the group's economic frameworks, as BRICS is an informal multilateral grouping.
India’s 'Look West' policy is constitutionally mandated by the Directive Principles of State Policy regarding the promotion of international peace and security.

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 253 grants Parliament plenary power to legislate for treaty implementation, overriding the federal distribution of powers (State List). Statement 2 is incorrect; while BRICS is an informal grouping, specific economic frameworks or treaties arising from it (e.g., NDB agreements) may require legislative or executive approval depending on their nature, and the blanket statement that it "does not require" parliamentary ratification is factually sweeping and incorrect in the context of binding international obligations. Statement 3 is correct; Article 51 (DPSP) directs the State to foster respect for international law and treaty obligations.

⚠️ UPSC Prelims Trap Alert: UPSC often uses the phrase "does not require" in international relations questions to test if you confuse 'informal groupings' with 'lack of legal procedure' for binding commitments.

Syllabus Match: GS Paper 2 - International Relations / Constitutional Provisions

Question 2: Outer Space Security and Governance

Context: With increasing concerns over 'on-orbit space control weapons', consider the following statements:

The 1967 Outer Space Treaty (OST) explicitly prohibits the placement of conventional weapons in outer space, but remains ambiguous regarding 'dual-use' technologies.
'On-orbit' space control weapons refer to capabilities designed to interfere with, damage, or destroy satellites while they are in orbit, rather than launching missiles from the ground.
India is not a signatory to the Outer Space Treaty, which allows it greater flexibility in its space weaponization policy.

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: (a) 1 and 2 only

Detailed Explanation: Statement 1 is correct; the OST prohibits WMDs in space but is silent on conventional or dual-use technologies. Statement 2 is correct; this is the definition of on-orbit counter-space capabilities. Statement 3 is incorrect; India is a signatory to the Outer Space Treaty (1967).

⚠️ UPSC Prelims Trap Alert: UPSC tests the distinction between the ban on Weapons of Mass Destruction (WMDs) and the silence on conventional weapons in the OST. Do not assume 'space is demilitarized' globally.

Syllabus Match: GS Paper 2 - Security Challenges and International Agreements

Question 3: Banking Liquidity and Orbital Mechanics

Context: Consider the following statements regarding economic liquidity and satellite orbits:

The Standing Deposit Facility (SDF) allows the RBI to absorb excess liquidity from the banking system without providing collateral to banks.
Geostationary Earth Orbit (GEO) satellites revolve around the Earth in the same direction as the Earth's rotation (west to east).
Medium Earth Orbit (MEO) is primarily used for Earth observation satellites as they provide the highest resolution images due to their proximity to the planet.

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: (a) 1 and 2 only

Detailed Explanation: Statement 1 is correct; SDF is a collateral-free liquidity absorption tool introduced by the RBI. Statement 2 is correct; GEO satellites orbit at 35,786 km and match Earth's rotation. Statement 3 is incorrect; LEO (Low Earth Orbit), not MEO, is used for high-resolution Earth observation because it is closer to the surface (200–2,000 km). MEO is typically used for navigation satellites (like GPS).

⚠️ UPSC Prelims Trap Alert: UPSC frequently swaps LEO and MEO characteristics. Remember: LEO = Low = Close = High Resolution.

Syllabus Match: GS Paper 3 - Indian Economy (Banking) / Science & Tech (Space)

Question 4: Carbon Credits and Economic Indicators

Context: Consider the following statements regarding the Carbon Credits Trading Scheme (CCTS) and GDP computation:

The Carbon Credits Trading Scheme is governed by the Ministry of Environment, Forest and Climate Change (MoEFCC) as the primary regulatory authority.
Gross Value Added (GVA) at basic prices is calculated as: GVA = GDP + Subsidies on products - Indirect taxes on products.
The Bureau of Energy Efficiency (BEE) is the designated agency responsible for the issuance of carbon credit certificates under the CCTS.

Which of the statements given above is/are incorrect?

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

👉 Click to Reveal Answer & Detailed Explanation

Correct Answer: (c) 1 only

Detailed Explanation: Statement 1 is incorrect; the Carbon Credits Trading Scheme is governed by the Ministry of Power, not MoEFCC, as it falls under the Energy Conservation Act. Statement 2 is correct; GVA = GDP - Net Indirect Taxes (or GDP + Subsidies - Indirect Taxes). Statement 3 is correct; BEE acts as the administrator for the CCTS.

⚠️ UPSC Prelims Trap Alert: Always check the Ministry in charge of climate initiatives. Often, energy-related climate schemes are under the Ministry of Power, not the Ministry of Environment.

Syllabus Match: GS Paper 3 - Economy / Environment

Question 5: Urbanization and Migration Patterns

Context: Regarding global patterns of migration and rapid urbanization, consider the following statements:

According to the Census of India, a settlement is classified as 'urban' if it has a population of at least 5,000 and at least 75% of the male working population is engaged in non-agricultural pursuits.
Ravenstein’s 'Laws of Migration' suggest that the majority of migrants move only a short distance, and migration occurs in steps.
The 74th Constitutional Amendment Act mandates the creation of Ward Committees in all urban local bodies regardless of population size.

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: (a) 1 and 2 only

Detailed Explanation: Statement 1 is correct; this is the official Census definition of a Census Town. Statement 2 is correct; Ravenstein's laws are foundational to migration studies. Statement 3 is incorrect; the 74th Amendment mandates Wards Committees in municipalities with a population of 3 lakhs or more, not all.

⚠️ UPSC Prelims Trap Alert: UPSC loves to test the specific population thresholds in the 74th Amendment Act (e.g., 3 lakhs for Wards Committees, District Planning Committee composition).

Syllabus Match: GS Paper 1 - Urbanization / Geography

Prelims Revision Flashcards

Article 253: Empowers Parliament to make laws for implementing international treaties, overriding State List subjects.
Outer Space Treaty (1967): Bans WMDs in space, but does not explicitly ban conventional 'on-orbit' counter-space weapons.
SDF vs Repo: SDF is collateral-free; Repo requires government securities (G-Secs) as collateral.
GVA Formula: GDP = GVA + Indirect Taxes - Subsidies. Therefore, GVA = GDP - Indirect Taxes + Subsidies.
Urban Definition (Census): Population > 5,000; Density > 400/sq km; >75% of male working population in non-farm activities.
