Question 1 of 5
1. Question
1 pointsWhich of the following statements about the WMO State of Climate in Asia 2024 report is/are correct?
- The average Asian sea-surface-temperature (SST) warming rate during 1991-2024 was about 0.24 °C per decade, nearly twice the global average.
- In 2024, Japan recorded its hottest summer on record, with a national mean temperature anomaly exceeding +2 °C above the 1991-2020 baseline.
- Cyclone Asna was the only North-Indian-Ocean tropical cyclone of 2024 to exceed Category 3 intensity on the Saffir-Simpson scale.
- Twenty-three out of twenty-four monitored glaciers in the Central Himalayas and Tian Shan lost mass during the 2023-24 hydrological year.
Select the correct answer using the code below:
Correct
Answer:(a) 1 and 4 only
Statement 1 is Correct:The WMO notes that Asian sea-surface temperatures warmed at ≈ 0.24 °C per decade between 1991 and 2024, almost twice the global mean of 0.13 °C per decade. This accelerated ocean warming is especially pronounced in the northern Arabian Sea, East China Sea and Yellow Sea, and it amplifies monsoon-scale moisture transport and extreme-rainfall events.
Statement 2 is Incorrect:Japan’s summer of 2024 tied its previous record with a national anomaly of +1.76 °C above the 1991-2020 norm; it did not cross +2 °C. Heatwave duration was exceptional (April-Nov), but the numeric threshold in the statement overstates the anomaly.
Statement 3 is Incorrect: Cyclone Asna was unusual for forming in June over the Arabian Sea (only the fourth such event since 1891) yet it peaked below Category 3. Neither its central pressure nor its 1-minute sustained winds met Saffir-Simpson “major-hurricane” criteria, so the claim is wrong.
Statement 4 is Correct: Mass-balance monitoring shows 23 of 24 glaciers in the Central Himalayas and Tian Shan lost ice in 2023-24. Persistent warming and a weak winter snowpack are accelerating glacial lake growth, heightening GLOF and downstream water-security risks.

Question 2 of 5
2. Question
1 pointsWith reference to the Sustainable Development Report 2025 (10th edition), consider the following statements:
- Finland, Sweden and Denmark occupy the top three positions in overall SDG performance.
- Benin shows the greatest overall score improvement since 2015 among all UN member states.
- Only about 17 % of SDG targets worldwide are currently on track.
- The United States tops the “Multilateralism Index” owing to its high treaty participation.
How many of the above statements are correct?
Correct
Answer:C
Statement 1 is Correct: For the tenth year, Scandinavia dominates: Finland (1st), Sweden (2nd) and Denmark (3rd) have near-universal basic services, strong social-welfare systems and aggressive climate policies, giving them the highest composite SDG scores.
Statement 2 is Correct: Benin recorded the largest score jump (+14.5 points since 2015) owing to expanded primary-school enrolment, immunisation drives and rural electrification. Nepal, UAE and Peru follow, but none exceed Benin’s aggregate gain.
Statement 3 is Correct: SDSN calculates that globally only about 17 % of the 169 SDG targets are “on track”; most are either stagnating or regressing—especially those linked to climate action and biodiversity.
Statement 4 is Incorrect: On the Multilateralism Index, the United States ranks last (193rd) because it withdrew or signalled exit from several key treaties (UNFCCC funding pledges, UNESCO, WHO funding freeze, etc.) during the last decade. Barbados, not the US, tops the index.

Question 3 of 5
3. Question
1 pointsWhich of the following features of the U.S. B-2 Spirit bomber contribute directly to its low observability (“stealth”) characteristics?
- A “flying-wing” platform with no vertical tail surfaces
- Internal weapons bays that avoid external hard-points
- A radar-absorbent skin composed largely of ceramic composites
- Use of vectored-thrust nozzles to mask the infrared plume
Select the correct answer using the code below:
Correct
Answer:(a) 1 and 2 only
Statement 1 is Correct: A pure flying-wing platform removes vertical tails, smoothing right-angle surfaces that normally produce strong radar “corner reflections.” Combined with spline-blended edges, this gives the B-2 one of the lowest radar cross-sections ever measured for a bomber.
Statement 2 is Correct: All weapons—including the 13-tonne GBU-57A/B Massive Ordnance Penetrator—are carried in internal bays. By avoiding external pylons or fuel tanks the jet remains aerodynamically clean and, more importantly, leaves no metallic shapes for radar to “paint.”
Statement 3 is Incorrect: Stealth coatings on the B-2 are layered ferrite-impregnated epoxy and specialised RAM paints, not bulk “ceramic composites.” Ceramics are used sparingly around engine inlets for heat resistance, but they’re not the primary radar-absorbent material.
Statement 4 is Incorrect: The B-2 has fixed “saw-tooth” exhausts that flatten the plume and shield hot turbine faces; it does not use thrust-vectoring. Vectoring is seen on F-22/F-35 for agility, not on the B-2.

Question 4 of 5
4. Question
1 pointsConsider the following statements:
Statement I:
India’s sugar-ethanol and soybean processing industries are concerned that trade concessions under a new India–U.S. deal could harm their market competitiveness.Statement II:
The import of genetically modified maize and soybeans could disrupt feedstock supply, reduce farmer incomes, and increase logistical costs for domestic processors.Statement III:
India’s current ethanol production is predominantly based on surplus sugarcane rather than maize or grains.Which one of the following is correct in respect of the above statements?
Correct
Answer: (a)
Explanation:
- Statement I is correct – The sugar-ethanol and soybean sectors fear that concessions in trade agreements—like allowing GM maize/soy imports—will reduce their competitiveness and hurt domestic markets.
- Statement II is correct – Imports of GM maize for ethanol could lead to food-fuel trade-offs, affect poultry feed prices, and undermine the grain balance. GM soybean imports may hurt local processors (far from ports) and farmers (price depression). This explains the concern.
- Statement III is correct – Currently, only 32% of ethanol is produced from sugarcane (molasses/juice), while 68% already comes from grain-based feedstocks like maize. Thus, sugarcane-based ethanol production is in a more vulnerable position.
Statement II explains the economic threat, while Statement III explains the feedstock context — both contribute to explaining Statement I.
Hence, option (a) is correct.Incorrect

Question 5 of 5
5. Question
1 pointsConsider the following statements about Article 356 of the Constitution of India:
- A proclamation of President’s Rule must be approved by both Houses of Parliament within two months by absolute majority of the total membership of each House.
- Once approved, President’s Rule is valid for six months at a time and can be extended up to a maximum of three years with periodic approvals.
- Laws made by Parliament during President’s Rule automatically lapse once normal government is restored in the state.
- The very first instance of Article 356 was in Punjab (1951).
Which of the statements given above is/ are correct?
Correct
Answer:(b) 2 and 4 only
Statement 1 is Incorrect: Parliament must approve a proclamation within two months by a simple majority of members present and voting, not by an absolute majority of the total House strength.
Statement 2 is Correct: Each approval keeps President’s Rule for six months and, subject to 44th-Amendment safeguards (a continuing national emergency plus Election Commission nod that polls cannot be held), it may be renewed to an outer limit of three years.
Statement 3 is Incorrect: Central-made laws continue even after President’s Rule ends; they remain until altered or repealed by the re-instated state legislature. They are not coterminous with the proclamation.
Statement 4 isCorrect: The first ever Article 356 action was the Punjab proclamation of 20 June 1951, issued when the Gopi Chand Bhargava ministry lost majority soon after the first elections under the new Constitution.
