Question 1 of 5
1. Question
Consider the following statements regarding methane emissions from rice cultivation:
Methane is the second most important anthropogenic greenhouse gas after carbon dioxide.
Flooded paddy fields generate methane because anaerobic conditions promote methanogenic microbes.
Livestock is the only major anthropogenic source of methane besides rice cultivation.
Alternate Wetting and Drying (AWD) irrigation can reduce methane emissions without significantly reducing rice yields.
Which of the statements given above are correct?Correct
Solution (d)
Explanation:
Methane (CH₄) is the second most important anthropogenic greenhouse gas after carbon dioxide and possesses a Global Warming Potential (GWP) nearly 28 times higher than CO₂ over a 100-year period. Flooded paddy fields create oxygen-deficient (anaerobic) conditions that favour methanogenic microbes responsible for methane emissions. Besides rice cultivation, major anthropogenic sources include livestock (enteric fermentation), landfills, fossil-fuel extraction, and wastewater treatment. Therefore, Statement 3 is incorrect because it ignores several other significant methane sources. Alternate Wetting and Drying (AWD) irrigation interrupts anaerobic conditions and can substantially reduce methane emissions while maintaining productivity, making it an important climate-smart agricultural practice.
Why this question? Tests climate change–agriculture linkage using elimination-based statements.
Why important for UPSC? Methane mitigation is central to India’s climate commitments.

Question 2 of 5
2. Question
With reference to the PM-YASASVI Scheme, consider the following statements:
It is implemented by the Ministry of Social Justice and Empowerment.
It targets students belonging to OBCs, EBCs and Denotified, Nomadic & Semi-Nomadic Tribes.
Scholarships under the scheme are transferred through Direct Benefit Transfer (DBT).
It is exclusively meant for higher education scholarships.
Which of the statements given above are correct?Correct
Solution (a)
Explanation:
PM-YASASVI (PM Young Achievers Scholarship Award Scheme for Vibrant India) is implemented by the Ministry of Social Justice and Empowerment to promote educational opportunities for OBC, EBC, and DNT students. The scheme consolidates multiple scholarship programmes including pre-matric, post-matric, top-class school education, and hostel assistance. Scholarships are disbursed through the Direct Benefit Transfer (DBT) mechanism to ensure transparency and timely payment. Statement 4 is incorrect because the scheme is not confined to higher education alone; it covers school-level as well as post-school educational support. UPSC frequently tests scheme consolidation and beneficiary categories through statement-based questions.
Why this question? Tests beneficiary categories and nodal ministry.
Why important for UPSC? Welfare schemes remain recurring prelims themes.

Question 3 of 5
3. Question
Consider the following statements regarding the National Chambal Sanctuary:
It is India’s only tri-state riverine wildlife sanctuary.
It extends across Rajasthan, Madhya Pradesh and Uttar Pradesh.
It is an important habitat for the Gharial, Gangetic River Dolphin and Indian Skimmer.
Illegal sand mining mainly threatens forest cover and has little impact on aquatic biodiversity.
Which of the statements given above are correct?Correct
Solution (a)
Explanation:
The National Chambal Sanctuary, established in 1979, is India’s only tri-state riverine protected area jointly managed by Rajasthan, Madhya Pradesh, and Uttar Pradesh. It conserves one of northern India’s last relatively undisturbed river ecosystems and supports endangered species such as the Gharial, Gangetic River Dolphin, Indian Skimmer, Red-crowned Roofed Turtle, Mugger Crocodile, and Smooth-coated Otter. Statement 4 is incorrect because illegal sand mining destroys nesting sandbanks, alters river morphology, and degrades habitats essential for aquatic fauna. UPSC frequently links protected areas with conservation threats rather than asking only about locations.
Why this question? Integrates protected areas with ecological threats.
Why important for UPSC? Riverine biodiversity is increasingly relevant.

Question 4 of 5
4. Question
Karlapat Bauxite Block, recently seen in news, is significant because:
Correct
Solution (b)
Explanation:
Karlapat Bauxite Block, located in Kalahandi district of Odisha, is a greenfield mining block that has not been commercially mined earlier. It possesses around 207 million tonnes of bauxite resources with high alumina and low silica content, making it particularly suitable for alumina extraction through the Bayer Process. Odisha accounts for nearly 41% of India’s bauxite resources, underlining the strategic significance of the block for India’s aluminium industry. UPSC often asks mineral-resource questions by combining location, mineral quality, industrial applications, and extraction processes.
Why this question? Tests economic geography and mineral resources.
Why important for UPSC? Critical minerals are an emerging focus area.

Question 5 of 5
5. Question
Consider the following statements regarding Samudra Pradakshina:
It is the world’s first Tri-Service all-women circumnavigation sailing expedition.
The expedition was undertaken aboard IASV Triveni.
It crossed all three Great Capes during its voyage.
It was organised by the Indian Navy alone.
Which of the statements given above are correct?Correct
Solution (a)
Explanation:
Samudra Pradakshina is the world’s first Tri-Service all-women circumnavigation sailing expedition, organised by the Ministry of Defence. The crew comprised women officers from the Indian Army, Navy, and Air Force aboard the indigenously built IASV Triveni. The expedition crossed the Equator twice and rounded the three Great Capes—Cape Leeuwin, Cape Horn, and Cape of Good Hope—during its approximately nine-month voyage. Statement 4 is incorrect because the mission was a Tri-Service initiative rather than an Indian Navy-only expedition. UPSC frequently distinguishes between similar defence expeditions through organisational details.
Why this question? Tests defence current affairs with maritime geography.
Why important for UPSC? Defence achievements are frequently asked.
