Question 1 of 5
1. Question
With reference to recent findings about Planet Mercury, consider the following statements:
Mercury is shrinking because its large iron-rich core is gradually cooling and contracting.
The contraction of Mercury produces surface features such as wrinkle ridges, faults, and scarps.
Earlier estimates of Mercury’s shrinkage were likely overestimated because impact debris buried older contraction features.
Which of the statements given above is/are correct?Correct
Solution (b)
Explanation: Mercury has a large iron-rich core, and as its interior cools, the core contracts, compressing the mantle and crust, producing wrinkle ridges, faults, and scarps (statements 1 and 2 correct). Statement 3 is incorrect because impact debris can bury or obscure older contraction features, causing earlier estimates to be underestimated, not overestimated. The recent study suggests Mercury may have contracted about 30% more than previously thought, with its diameter possibly reduced by up to 23 km.
Why this question? Tests the cause-effect sequence of planetary contraction and the direction of estimation error.
Why important for UPSC? Science & Technology questions often test fundamental planetary processes.

2. Question
Consider the following statements regarding the Meenakshi-Sundareswarar Temple:
It is located in Madurai, Tamil Nadu, on the banks of the Vaigai River.
Its major expansion is associated with the Nayaka rulers.
It is a classic example of Nagara temple architecture.
Which of the statements given above is/are correct?Correct
Solution (b)
Explanation: The Meenakshi-Sundareswarar Temple is located in Madurai, Tamil Nadu, on the banks of the Vaigai River (statement 1 correct). Its present complex developed substantially under the Nayaka rulers, particularly Tirumalai Nayak and Vishwanatha Nayak (statement 2 correct). Statement 3 is incorrect because the temple is a classic example of Dravidian temple architecture, not Nagara. It is famous for its numerous gopurams, the Thousand Pillar Hall, and extensive temple corridors.
Why this question? Tests the temple-city-river-dynasty-architecture combination.
Why important for UPSC? Art & Culture questions frequently test such associations.

3. Question
With reference to Tso Kar Lake, consider the following statements:
It is a high-altitude freshwater lake located in Ladakh.
It was designated as a Ramsar Site in 2020.
It is an important habitat for the Black-necked Crane.
Which of the statements given above is/are correct?Correct
Solution (c)
Explanation: Tso Kar was designated a Ramsar Site in 2020, becoming India’s 42nd Ramsar Site (statement 2 correct). It is an important habitat for the Black-necked Crane, Bar-headed Goose, Kiang, and various high-altitude waterbirds (statement 3 correct). Statement 1 is incorrect because Tso Kar is a high-altitude hypersaline wetland system, not a freshwater lake. Its name means “White Lake,” referring to the white salt deposits around its margins.
Why this question? Tests the salinity trap—a common source of confusion for high-altitude lakes.
Why important for UPSC? Ramsar sites and their ecological characteristics are frequently tested.

Question 4 of 5
4. Question
Consider the following statements regarding Moth Bean:
Its scientific name is Vigna aconitifolia.
It is particularly suited to hot, arid and semi-arid regions.
It is a water-intensive crop requiring high rainfall.
Which of the statements given above is/are correct?Correct
Solution (b)
Explanation: Moth bean’s scientific name is Vigna aconitifolia (statement 1 correct). It is a pulse/legume crop particularly suited to hot, arid and semi-arid regions, especially western Rajasthan (statement 2 correct). Statement 3 is incorrect because moth bean is a drought-tolerant crop that can withstand low and erratic rainfall (150–250 mm) and prolonged dry spells. It is cultivated largely under rainfed conditions, making it the opposite of a water-intensive crop like paddy.
Why this question? Tests the crop-characteristics trap by contrasting drought tolerance with water intensity.
Why important for UPSC? Agriculture questions often test crop suitability and climate resilience.

Statement 1 is incorrect because Willingdon Island is a man-made/artificial island, created through dredging and reclaiming material from Vembanad Lake during the development of Cochin Port. It was named after Lord Willingdon, Viceroy of India (1931–36).
Why this question? Tests the natural vs. artificial island trap—a classic UPSC factual distractor.
Why important for UPSC? Geography questions often test the origin and significance of coastal features.
