Question 1 of 5
1. Question
Consider the following statements regarding Atmospheric Aerosols:
Primary aerosols are emitted directly into the atmosphere, whereas secondary aerosols are formed through chemical reactions in the atmosphere.
Black carbon primarily contributes to atmospheric cooling by reflecting incoming solar radiation.
Aerosols can act as Cloud Condensation Nuclei (CCN), thereby influencing cloud formation and rainfall patterns.
Compared to greenhouse gases, aerosols generally have a much shorter atmospheric lifetime.
Which of the statements given above are correct?Correct
Solution (c)
Explanation:
Atmospheric aerosols are tiny solid or liquid particles suspended in the atmosphere. Primary aerosols such as dust, sea salt, and volcanic ash are emitted directly, whereas secondary aerosols form through atmospheric chemical reactions involving gases like SO₂, NOx, and VOCs. Aerosols influence climate by interacting with solar radiation and by serving as Cloud Condensation Nuclei (CCN), thereby affecting cloud properties, rainfall, and monsoon behaviour. Statement 2 is incorrect because black carbon absorbs sunlight and contributes to atmospheric warming, unlike scattering aerosols that produce a cooling effect. Aerosols remain in the atmosphere for only days to weeks, much shorter than most greenhouse gases.
Why this question? Tests conceptual understanding of aerosols and radiative forcing.
Why important for UPSC? Climate-modifying agents are recurring Science & Environment themes.
PYQ Pattern Link: Similar to UPSC questions on greenhouse gases and atmospheric constituents.Incorrect

Question 2 of 5
2. Question
Consider the following statements regarding Picrorhiza kurroa (Kutki):
It is an endangered medicinal herb native to the alpine and sub-alpine Himalayas.
It belongs to the family Plantaginaceae.
It is included in Appendix I of CITES.
Sustainable cultivation through stolon harvesting allows regeneration of the parent plant.
Which of the statements given above are correct?Correct
Solution (d)
Explanation:
Picrorhiza kurroa (Kutki) is a high-value Himalayan medicinal herb occurring between 2,700 and 4,500 metres. It belongs to the Plantaginaceae family and is widely used in Ayurveda for treating liver disorders and digestive ailments. The species is listed as Endangered on the IUCN Red List and included in CITES Appendix II, not Appendix I; therefore, Statement 3 is incorrect. A recently adopted sustainable cultivation model involves harvesting only the stolons, allowing the parent plant to regenerate naturally and reducing pressure on wild populations. UPSC frequently tests medicinal plants by combining taxonomy, conservation status, and sustainable harvesting techniques.
Why this question? Integrates taxonomy with conservation biology.
Why important for UPSC? Medicinal plants and CITES listings are frequently tested.

Question 3 of 5
3. Question
With reference to Project Kusha, consider the following statements:
It is an indigenous Long-Range Surface-to-Air Missile (LRSAM) programme developed by DRDO.
It is intended to complement systems such as S-400, Akash and Barak-8.
It is primarily designed to intercept ballistic missiles during their exo-atmospheric phase.
It is planned to be integrated with the Integrated Air Command and Control System (IACCS).
Which of the statements given above are correct?Correct
Solution (d)
Explanation:
Project Kusha is DRDO’s indigenous Long-Range Surface-to-Air Missile (LRSAM) programme aimed at strengthening India’s layered air defence architecture. It is designed to complement systems such as the S-400, Akash, and Barak-8 by intercepting aircraft, cruise missiles, drones, and AEW&C platforms. The system will be integrated with the Indian Air Force’s Integrated Air Command and Control System (IACCS) for network-centric operations. Statement 3 is incorrect because Project Kusha is not primarily designed for dedicated exo-atmospheric ballistic missile interception. UPSC often distinguishes between air-defence missiles and ballistic missile defence systems.
Why this question? Tests classification of missile systems.
Why important for UPSC? Defence technology is an emerging prelims focus.
PYQ Pattern Link: Similar to Akash, S-400 and BrahMos questions.Incorrect

Question 4 of 5
4. Question
Which of the following correctly describes the Black Sea?
It is connected to the Mediterranean Sea through the Bosporus–Sea of Marmara–Dardanelles route.
It is connected to the Sea of Azov through the Kerch Strait.
It is bordered by six countries.
It is the world’s largest enclosed inland water body.
Select the correct answer using the code below:Correct
Solution (a)
Explanation:
The Black Sea is a semi-enclosed inland sea located between Eastern Europe and Western Asia. It is connected to the Mediterranean Sea through the Bosporus Strait, Sea of Marmara, and Dardanelles Strait, while the Kerch Strait links it to the Sea of Azov. Six countries—Turkey, Bulgaria, Romania, Ukraine, Russia, and Georgia—border the Black Sea. Statement 4 is incorrect because the Caspian Sea, not the Black Sea, is the world’s largest enclosed inland water body. UPSC frequently asks map-based questions involving seas, straits, bordering countries, and associated conventions such as the Montreux Convention.
Why this question? Tests map-based strategic geography.
Why important for UPSC? Strategic seas and maritime routes are repeatedly asked.

Question 5 of 5
5. Question
Consider the following statements regarding the Crime and Criminal Tracking Network & Systems (CCTNS):
It was launched as a Mission Mode Project under the National e-Governance Plan.
The Ministry of Home Affairs is the nodal ministry.
The National Crime Records Bureau (NCRB) is the implementing agency.
CCTNS and the Inter-Operable Criminal Justice System (ICJS) are identical platforms.
Which of the statements given above are correct?Correct
Solution (a)
Explanation:
Launched in 2009 under the National e-Governance Plan, CCTNS is a Mission Mode Project aimed at digitising policing across India. The Ministry of Home Affairs is the nodal ministry, while the National Crime Records Bureau (NCRB) serves as the implementing agency. CCTNS enables digital FIRs, investigation records, and nationwide crime databases. Statement 4 is incorrect because ICJS is a broader integration platform linking police, courts, prisons, prosecution, forensics, and fingerprint databases, whereas CCTNS specifically focuses on digital policing. UPSC often tests e-governance platforms by asking candidates to distinguish between related digital initiatives.
Why this question? Tests governance architecture and digital policing.
Why important for UPSC? Mission Mode Projects are important prelims topics.
