The Current Affairs questions are based on sources like ‘The Hindu’, ‘Indian Express’ and ‘PIB’, which are very important sources for UPSC Prelims Exam. The questions are focused on both the concepts and facts. The topics covered here are generally different from what is being covered under ‘Daily Current Affairs/Daily News Analysis (DNA) and Daily Static Quiz’ to avoid duplication. The questions would be published from Monday to Saturday before 2 PM. One should not spend more than 10 minutes on this initiative.
Gear up and Make the Best Use of this initiative.
Do remember that, “the difference between Ordinary and EXTRA-Ordinary is PRACTICE!!”

Question 1 of 5
1. Question
Q1. Consider the following statements regarding the Joint Crediting Mechanism (JCM):
- It is a multilateral mechanism established under the Paris Agreement to facilitate global carbon trading.
- The mechanism enables transfer of low-carbon technologies from Japan to partner countries.
- Emission reductions achieved through approved projects are quantified and converted into carbon credits shared by participating countries.
Which of the statements given above is/are correct?
Correct
Q.1) Solution (a)
Explanation:
- The Joint Crediting Mechanism (JCM) is a bilateral carbon-crediting mechanism initiated by Japan in 2013, not a multilateral arrangement under the Paris Agreement. Hence Statement 1 is incorrect.
- It facilitates the deployment of advanced low-carbon and decarbonization technologies in partner countries, making Statement 2 correct.
- The emission reductions achieved through approved projects are measured, verified and converted into carbon credits which are shared between Japan and the partner country; therefore Statement 3 is correct.
UPSC often creates traps by confusing bilateral climate arrangements with mechanisms established under UNFCCC or the Paris Agreement.
JCM represents a market-based mitigation instrument operating outside the formal carbon market architecture of the Paris Agreement.
Why this question?
Tests distinction between bilateral and multilateral climate mechanisms.Why important for UPSC?
Carbon markets and mitigation instruments are recurring UPSC themes.PYQ Pattern Link
Similar elimination logic used in Paris Agreement and carbon-credit PYQs.Incorrect

Question 2 of 5
2. Question
Q2. With reference to INS Tarkash, which one of the following statements is correct?
Correct
Q.2) Solution (b)
Explanation:
INS Tarkash is a frontline Talwar-class stealth frigate commissioned in 2012 and based on the Russian Krivak-III class design.
It is designed for anti-surface, anti-submarine and anti-air warfare.
- Option (a) is incorrect because it is neither an aircraft carrier nor under Eastern Naval Command.
- Option (c) incorrectly identifies it as a nuclear-powered submarine.
- Option (d) confuses frigates with destroyers and attributes capabilities not associated with INS Tarkash.
UPSC frequently asks questions where the classification of military platforms—frigate, corvette, destroyer, submarine, aircraft carrier—becomes the key differentiator. Understanding naval terminology is essential for solving such questions through elimination.
Why this question?
Tests platform classification and naval warfare concepts.Why important for UPSC?
Defence assets frequently appear in current affairs-based prelims.PYQ Pattern Link
Comparable to UPSC questions on Arihant, Vikramaditya and Tejas.Incorrect

Question 3 of 5
3. Question
Q3. Consider the following statements regarding cosmic rays and muons:
- Muons are generated when high-energy cosmic rays interact with molecules in Earth’s atmosphere.
- Cosmic rays consist exclusively of electromagnetic radiation originating from stars.
- GRAPES-3 studies variations in cosmic-ray intensity and solar activity.
Which of the statements given above are correct?
Correct
Q.3) Solution (b)
Explanation:
Cosmic rays are primarily high-energy charged particles such as protons and atomic nuclei originating from various astrophysical sources. Therefore Statement 2 is incorrect because they are not exclusively electromagnetic radiation. When these cosmic rays strike atmospheric molecules, they generate secondary particles including muons, making Statement 1 correct. GRAPES-3 at Ooty measures cosmic-ray intensity variations and studies solar activity, space weather and geomagnetic effects; thus Statement 3 is correct.
UPSC often frames questions by mixing particle physics with astronomy, requiring candidates to distinguish between cosmic rays, gamma rays, neutrinos and electromagnetic radiation.
Why this question?
Creates conceptual trap between particles and radiation.Why important for UPSC?
Indian scientific observatories are increasingly asked in prelims.PYQ Pattern Link
Similar approach used in neutrino and gravitational-wave questions.Incorrect

Question 4 of 5
4. Question
Q4. Which one of the following best explains why the Knob-Billed Duck is considered ecologically significant despite being listed as “Least Concern” by IUCN?
Correct
Q.4) Solution (b)
Explanation:
- The Knob-Billed Duck (Comb Duck) is not considered threatened globally and is listed as Least Concern.
- However, unusual sightings can provide insights into ecological changes such as habitat shifts, wetland dynamics and alterations in local movement patterns. Hence Option (b) is correct.
It is not a keystone predator, making Option (a) incorrect. It is widely distributed across Africa and South Asia and is not endemic to India; therefore Option (c) is wrong. It is not a long-distance migratory bird but exhibits local and seasonal movements, eliminating Option (d). UPSC often tests ecological significance beyond conservation status, making such questions highly relevant.
Why this question?
Tests ecological interpretation beyond IUCN status.Why important for UPSC?
Wetlands and bird migration remain recurring environmental topics.PYQ Pattern Link
Resembles UPSC questions linking species sightings with ecosystems.Incorrect

Question 5 of 5
5. Question
Q5. Consider the following statements regarding the National Statistical Commission (NSC):
- It is a constitutional body established under Article 280 of the Constitution.
- It was constituted following recommendations of the Rangarajan Commission.
- The Chief Statistician of India serves as an ex-officio member.
- It functions under the Ministry of Statistics and Programme Implementation.
Which of the statements given above are correct?
Correct
Q.5) Solution (a)
Explanation:
- The National Statistical Commission is a non-statutory advisory body, not a constitutional institution; therefore Statement 1 is incorrect.
- It was constituted in 2005 based on recommendations of the Rangarajan Commission, making Statement 2 correct.
- The Chief Statistician of India serves as an ex-officio member, so Statement 3 is correct.
- The commission functions under the Ministry of Statistics and Programme Implementation (MoSPI), making Statement 4 correct.
UPSC often asks candidates to distinguish between constitutional, statutory and executive bodies. Confusing NSC with institutions such as Finance Commission or Election Commission is a common trap.
Why this question?
Tests classification of institutions and commissions.Why important for UPSC?
Governance bodies are frequent prelims subjects.PYQ Pattern Link
