Daily UPSC Prelims Quiz: 5 High-Yield Questions with Detailed Explanations (October 13, 2026)

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’s Foreign Policy & Constitutional Directives

Context / Statement: With India recalibrating its engagement within the BRICS framework amidst West Asian geopolitical instability, consider the following statements regarding the Constitutional basis of India's foreign policy:

  1. Article 51 of the Indian Constitution mandates the State to endeavour to foster respect for international law and treaty obligations in the dealings of organised peoples with one another.
  2. The power to enter into treaties with foreign nations is exclusively vested in the Parliament under Entry 14 of the Union List.
  3. India’s participation in multilateral groupings like BRICS aligns with 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

๐Ÿ‘‰ Click to Reveal Answer & Detailed Explanation

Correct Answer: (c) 1 and 3 only

Detailed Explanation: Statement 1 is correct; Article 51 (DPSP) explicitly directs the State to promote international peace and security. Statement 2 is incorrect; while the Parliament has the power to legislate on international treaties (Entry 14), the *power to enter into treaties* is an executive function of the Union Government (Article 73/Article 253). Statement 3 is correct; India's proactive engagement in BRICS is a strategic application of Article 51.

⚠️ UPSC Prelims Trap Alert: UPSC often conflates 'Legislative Power to implement treaties' (Parliament) with the 'Executive Power to sign treaties' (President/Cabinet). Always check if the statement refers to *making* vs *implementing*.

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

Question 2: Outer Space Governance & Weaponisation

Context / Statement: In light of the rising concerns regarding 'on-orbit space control weapons', consider the following statements regarding the Outer Space Treaty (1967):

  1. The Treaty explicitly prohibits the placement of conventional weapons in Earth's orbit, including kinetic anti-satellite (ASAT) missiles.
  2. The Treaty declares that outer space, including the Moon and other celestial bodies, is not subject to national appropriation by claim of sovereignty.
  3. States are responsible for national activities in outer space, whether carried out by governmental agencies or non-governmental entities.

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

๐Ÿ‘‰ Click to Reveal Answer & Detailed Explanation

Correct Answer: (b) 2 and 3 only

Detailed Explanation: Statement 1 is incorrect. The 1967 Outer Space Treaty prohibits the placement of *nuclear weapons or other weapons of mass destruction* in orbit, but it does *not* explicitly ban conventional weapons or kinetic ASAT technology, which remains a major loophole in international space law. Statements 2 and 3 are accurate reflections of Articles II and VI of the Treaty.

⚠️ UPSC Prelims Trap Alert: UPSC tests the distinction between "Weapons of Mass Destruction" (banned in orbit) and "Conventional Weapons" (legally ambiguous). Do not assume the treaty bans *all* weapons.

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

Question 3: Satellite Orbits & Telecommunications

Context / Statement: With the increasing demand for high-speed internet and Earth observation, consider the following statements regarding satellite orbits:

  1. Geostationary Earth Orbit (GEO) satellites appear stationary relative to a fixed point on Earth, making them ideal for weather monitoring and direct-to-home TV.
  2. Low Earth Orbit (LEO) satellites require a much larger number of satellites to provide global coverage compared to MEO or GEO.
  3. Medium Earth Orbit (MEO) is typically used for GPS and other navigation systems due to its lower latency compared to GEO.

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

๐Ÿ‘‰ Click to Reveal Answer & Detailed Explanation

Correct Answer: (d) 1, 2 and 3

Detailed Explanation: All statements are correct. GEO satellites orbit at ~35,786 km, matching Earth's rotation. LEO (approx 500-2,000 km) provides low latency but requires a large 'constellation' for continuous coverage. MEO (approx 2,000-35,000 km) is the sweet spot for Global Navigation Satellite Systems (GNSS) like GPS.

⚠️ UPSC Prelims Trap Alert: Students often confuse 'Latency' (time delay) with 'Coverage'. LEO has low latency but high coverage velocity (requires more satellites); GEO has high latency but static coverage.

Syllabus Match: GS Paper 3 - Space Technology

Question 4: Carbon Credits Trading Scheme (CCTS)

Context / Statement: Regarding the institutional framework for the Carbon Credits Trading Scheme (CCTS) in India, consider the following statements:

  1. The Bureau of Energy Efficiency (BEE) under the Ministry of Power is the nodal agency for the implementation of the Carbon Credit Trading Scheme.
  2. The CCTS aims to facilitate the reduction of greenhouse gas emissions by creating a market-based mechanism for carbon credits.
  3. The Carbon Credit Trading Scheme is legally backed by the Environment (Protection) Act, 1986.

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

๐Ÿ‘‰ Click to Reveal Answer & Detailed Explanation

Correct Answer: (a) 1 and 2 only

Detailed Explanation: Statements 1 and 2 are correct. Statement 3 is incorrect; the CCTS is empowered by the Energy Conservation (Amendment) Act, 2022, which amended the Energy Conservation Act, 2001, not the Environment (Protection) Act.

⚠️ UPSC Prelims Trap Alert: UPSC loves swapping the Acts. Always link Carbon Credit Trading to the Energy Conservation Act (Ministry of Power), not the Environment (Protection) Act (Ministry of Environment, Forest and Climate Change).

Syllabus Match: GS Paper 3 - Environment / Economy

Question 5: Urbanisation & Migration Patterns

Context / Statement: With rapid urbanisation in India, consider the following statements regarding the Census definition of urban areas:

  1. A 'Statutory Town' is an area with a municipality, corporation, cantonment board, or notified town area committee.
  2. A 'Census Town' must have a minimum population of 5,000, 75% of the male working population engaged in non-agricultural pursuits, and a density of at least 400 persons per sq km.
  3. Migration from rural to urban areas is primarily driven solely by the 'push factor' of agricultural distress.

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

๐Ÿ‘‰ Click to Reveal Answer & Detailed Explanation

Correct Answer: (a) 1 and 2 only

Detailed Explanation: Statements 1 and 2 are correct definitions used by the Census of India. Statement 3 is incorrect because migration is a complex interplay of both 'push factors' (distress, lack of opportunity) and 'pull factors' (better wages, infrastructure, education, urban amenities). Using the word "solely" makes the statement incorrect.

⚠️ UPSC Prelims Trap Alert: Beware of absolute words like "solely", "only", or "exclusively" in social science questions. Migration dynamics are multi-factorial.

Syllabus Match: GS Paper 1 - Urbanisation / Population
