Which of the statements given above is/are correct?

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

ЁЯСЙ Click to Reveal Answer & Detailed Explanation

Correct Answer: (b) 1 and 3 only

Detailed Explanation: Statement 1 is correct. BRICS underwent a significant expansion, incorporating major West Asian geopolitical and energy heavyweights like Saudi Arabia, UAE, Iran, and Egypt, transforming the grouping's energy and geopolitical footprint. Statement 2 is incorrect. India actively engages West Asia not only bilaterally but also through innovative plurilateral and minilateral platforms such as I2U2 (India, Israel, UAE, USA) and multilateral forums like BRICS. Statement 3 is correct. The New Development Bank (NDB), originally conceived during the Fortaleza Summit, is headquartered in Shanghai, China, and focuses on mobilizing resources for infrastructure and sustainable development projects.

⚠️ UPSC Prelims Trap Alert: UPSC frequently uses absolute exclusionary words like "exclusively" or "only" (as in Statement 2) to trap aspirants regarding India's multi-alignment foreign policy.

Syllabus Match: GS Paper 2 - Bilateral, regional and global groupings and agreements involving India and/or affecting India's interests.

Question 2: Outer Space Governance & On-Orbit Space Control Weapons

Context / Statement: Consider the following statements regarding space security and satellite orbits:

  1. The Outer Space Treaty of 1967 completely prohibits the placement of all conventional weapons, including co-orbital space control systems, in Earth orbit.
  2. Low Earth Orbit (LEO) is typically situated between 160 km and 2,000 km above the Earth's surface and is increasingly congested with satellite constellations.
  3. Anti-Satellite (ASAT) kinetic tests generate long-lasting orbital debris fields that pose severe operational hazards to crewed and uncrewed space assets across multiple orbital regimes.

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

ЁЯСЙ Click to Reveal Answer & Detailed Explanation

Correct Answer: (b) 2 and 3 only

Detailed Explanation: Statement 1 is incorrect. The Outer Space Treaty (OST) of 1967 strictly prohibits the placement of nuclear weapons or weapons of mass destruction (WMD) in orbit, but it contains significant legal loopholes regarding conventional weapons, dual-use technology, and 'on-orbit space control weapons' (such as robotic arm interceptors and co-orbital jammers). Statement 2 is correct. LEO lies close to Earth (160 km to 2,000 km) and hosts critical Earth-observation and communication mega-constellations. Statement 3 is correct. Kinetic ASAT tests shatter targets into thousands of high-velocity fragments, creating persistent space debris that threatens global space infrastructure under the Kessler syndrome.

⚠️ UPSC Prelims Trap Alert: UPSC tests legal precision by stating treaties ban *all* weapons when international space law historically differentiates between WMDs and conventional armaments.

Syllabus Match: GS Paper 3 - Awareness in the fields of IT, Space, Computers, and Security Challenges.

Question 3: Quantum Computing & Cryptography

Context / Statement: Consider the following statements regarding quantum computing principles and its impact on the digital economy:

  1. Quantum computers utilize classical bits that are manipulated using quantum logic gates to simultaneously represent multiple states.
  2. Quantum supremacy denotes the milestone where a programmable quantum device solves a computational problem that is intractable for classical supercomputers.
  3. Shor’s algorithm executed on a fault-tolerant quantum computer poses a severe mathematical threat to widely deployed public-key cryptographic systems like RSA and ECC.

Which of the statements given above is/are correct?

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

ЁЯСЙ Click to Reveal Answer & Detailed Explanation

Correct Answer: (c) 2 and 3 only

Detailed Explanation: Statement 1 is incorrect. Quantum computers do not use *classical bits* (which can only be 0 or 1); they use **qubits** (quantum bits) which leverage the fundamental quantum mechanical phenomena of superposition and entanglement. Statement 2 is correct. Quantum supremacy (or quantum advantage) marks the point where quantum processors outperform classical supercomputers on specific benchmark computational tasks. Statement 3 is correct. Shor's algorithm can efficiently find the prime factors of composite numbers, directly undermining RSA and Elliptic Curve Cryptography (ECC) encryption standards that secure global digital transactions and communications.

⚠️ UPSC Prelims Trap Alert: Watch out for technical terminology substitution (e.g., swapping 'qubits' with 'classical bits' in foundational physics statements).

Syllabus Match: GS Paper 3 - Science and Technology- developments and their applications and effects in everyday life.

Question 4: RBI Liquidity Management & Monetary Policy

Context / Statement: Consider the following statements regarding liquidity management tools used by the Reserve Bank of India (RBI):

  1. Excess liquidity in the banking system often depresses short-term market interest rates, such as the Weighted Average Call Rate (WACR), below the RBI's repo rate.
  2. The Standing Deposit Facility (SDF) is a collateralized liquidity absorption tool that requires commercial banks to pledge government securities to park surplus funds with the RBI.
  3. The RBI deploys Variable Rate Reverse Repo (VRRR) auctions as a primary fine-tuning instrument to absorb surplus systemic liquidity from the banking sector.

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

ЁЯСЙ Click to Reveal Answer & Detailed Explanation

Correct Answer: (c) 1 and 3 only

Detailed Explanation: Statement 1 is correct. When liquidity is in surplus, banks compete to lend short-term funds, driving interbank rates like WACR below the policy repo rate towards the SDF rate. Statement 2 is incorrect. The Standing Deposit Facility (SDF), introduced without amending the RBI Act via an amendment to Section 17, is a **collateral-free** liquidity absorption tool—banks do not need to pledge government securities to park funds with the RBI. Statement 3 is correct. The RBI uses VRRR auctions of varying tenors to absorb excess liquidity from the banking system flexibly.

⚠️ UPSC Prelims Trap Alert: UPSC often tests whether liquidity tools like SDF require collateral. Remember that SDF is collateral-free, unlike traditional reverse repo operations.

Syllabus Match: GS Paper 3 - Indian Economy and issues relating to planning, mobilization of resources, growth, development and employment.

Question 5: Rapid Urbanisation & Migration Dynamics

Context / Statement: Consider the following statements regarding urbanisation patterns and migration in India and globally:

  1. In India, a 'statutory town' is defined under Census guidelines by the presence of a municipal corporation, municipality, cantonment board, or notified town area committee, regardless of population density.
  2. Climate change acts as an accelerating structural 'push' factor, intensifying rural-to-urban migration and cross-border displacement globally.
  3. Unplanned peri-urbanisation and suburban sprawl frequently result in the loss of fertile agricultural land, worsening urban heat island effects and flood vulnerabilities.

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

ЁЯСЙ Click to Reveal Answer & Detailed Explanation

Correct Answer: (d) 1, 2 and 3

Detailed Explanation: All statements are correct. Statement 1 is accurate because the Office of the Registrar General & Census Commissioner classifies urban areas into two categories: Statutory Towns (all places with a municipal corporation, municipality, cantonment board, etc., by law) and Census Towns (which must meet economic and demographic thresholds like population ≥ 5,000, 75%+ male workforce in non-agricultural pursuits, and density ≥ 400 persons/sq km). Statement 2 correctly highlights climate-induced migration driven by environmental degradation, droughts, and extreme weather events acting as severe push factors. Statement 3 reflects how unbridled urban sprawl converts ecologically vital green covers and agricultural lands into impermeable concrete surfaces, worsening urban flooding and urban heat island (UHI) intensity.

⚠️ UPSC Prelims Trap Alert: Aspirants often confuse the criteria of Statutory Towns (administrative definition) with Census Towns (demographic/economic criteria).

Syllabus Match: GS Paper 1 - Population and Associated Issues, Poverty and Developmental Issues, Urbanization, their problems and remedies.

Prelims Revision Flashcards

  • BRICS West Asian Expansion: Saudi Arabia, UAE, Iran, and Egypt joined BRICS, shifting global energy governance and multilateral dynamics.
