Q1:

The Ayni Airbase, recently in the news, holds strategic importance for India due to which of the following reasons?

1.   It was India’s only full-fledged overseas military base developed and maintained for nearly two decades.

2.   It is located close to the Wakhan Corridor, giving India surveillance advantage over Pakistan-occupied Kashmir (PoK) and China’s Xinjiang province.

3.   It has been used by India for humanitarian evacuation operations.

4.   It hosts a joint India–Russia air detachment under the Shanghai Cooperation Organisation (SCO) framework.

Select the correct answer using the code given below:

A: 1 and 2 only

B: 1,3 and 4 only

C: 1, 2 and 3 only

D: 1, 2, 3 and 4

Show

Answer: C

Explanation:

Statement 1 – Correct: Ayni was India’s only full-fledged overseas airbase, developed since early 2000s in Tajikistan.

Statement 2 – Correct: It is located about 20 km from Afghanistan’s Wakhan Corridor, which borders PoK and China’s Xinjiang, giving India strategic observation capability.

Statement 3 – Correct: Ayni was used to evacuate Indian nationals from Afghanistan after the Taliban’s 2021 takeover.

Statement 4 – Incorrect: There is no joint Indo-Russian SCO air detachment at Ayni. In fact, Russia’s and China’s pressure contributed to Tajikistan’s reluctance to renew India’s lease.

Q2:

With reference to recent scientific findings presented ahead of COP30, consider the following statements:

1.   The rate of global temperature rise has accelerated to nearly 0.27°C per decade, about 50% faster than during the 1990s and 2000s.

2.   The global mean sea level is rising at around 4.5 mm per year, which is more than double the 20th-century average.

3.   The world is projected to breach the 1.5°C warming threshold around 2050 if current emission trends continue.

4.   Coral reefs and the Amazon rainforest are among the ecosystems approaching critical tipping points.

Which of the statements given above are correct?

A: 1 and 2 only

B: 1,3 and 4 only

C: 1, 2 and 4 only

D: 1, 2, 3 and 4

Show

Answer: C

Explanation:

Statement 1 – Correct: According to the updated IPCC data, global temperatures are now rising at 0.27°C per decade, almost 50% faster than the pace observed in earlier decades.

Statement 2 – Correct: Sea levels are rising at about 4.5 mm per year, which is indeed more than double the 20th-century rate (~1.5–2 mm/year).

Statement 3 – Incorrect: The world is on track to breach the 1.5°C threshold by 2030, not 2050 — indicating a far shorter timeline for critical climate limits.

Statement 4 – Correct: Both coral reefs (due to marine heatwaves) and the Amazon rainforest (due to deforestation and warming) are nearing irreversible tipping points.

Q3:

With reference to the 2025 United Nations Climate Change Conference (COP30), consider the following statements:

1.   COP30 is being hosted by Brazil in the city of Belém, located in the Amazon region, at the Hangar Convention Centre.

2.   The Brazilian government symbolically transferred the nation’s capital from Brasília to Belém during the conference period.

3.   André Corrêa do Lago, a Brazilian diplomat with experience in global climate negotiations, serves as the President of COP30.

4.   The decision to host COP30 in Belém was first announced during COP28 and officially confirmed in 2024.

Which of the statements given above are correct?

A: 1 and 2 only

B: 1 and 3 only

C: 1, 2 and 3 only

D: 1, 2, 3 and 4

Show

Answer: C

Explanation:

Statement 1 – Correct: COP30 (2025) is indeed being held in Belém, in the Amazon region of Brazil, at the Hangar Convention Centre from 10–21 November 2025.

Statement 2 – Correct: President Lula da Silva signed a law temporarily transferring Brazil’s capital from Brasília to Belém during COP30 (11–21 Nov 2025), symbolizing national focus on climate and the Amazon.

Statement 3 – Correct: In January 2025, Brazilian diplomat André Corrêa do Lago — a veteran climate negotiator — was appointed President of COP30.

Statement 4 – Incorrect: The candidacy was announced in 2022 during COP27 (Sharm El-Sheikh, Egypt) and officially confirmed in January 2023, not COP28 or 2024.

Q4:

With reference to the recent ICAR study (2017–2023) on Soil Organic Carbon (SOC) across India, consider the following statements:

1.   The study found that low levels of soil organic carbon are strongly associated with higher micronutrient deficiencies in soils.

2.   Soil organic carbon content shows a positive correlation with elevation and a negative correlation with temperature.

3.   Rice- and pulse-based cropping systems generally show higher soil organic carbon compared to wheat- and coarse-grain-based systems.

4.   The study concluded that fertilizer misuse has little impact on soil organic carbon loss compared to climatic factors.

Which of the statements given above are correct?

A: 1 and 2 only

B: 1,3 and 4 only

C: 1, 2 and 3 only

D: 1, 2, 3 and 4

Show

Answer: C

Explanation:

Statement 1 – Correct: The study clearly found an inverse relationship between organic carbon levels and micronutrient deficiency — low SOC means high deficiency.

Statement 2 – Correct: SOC is positively correlated with elevation (higher in hilly regions) and negatively correlated with temperature (lower in hotter regions such as Rajasthan and Telangana).

Statement 3 – Correct: Rice- and pulse-based cropping systems tend to maintain higher organic carbon, due to better residue retention and root biomass, compared to wheat or coarse cereals.

Statement 4 – Incorrect: The study explicitly identifies unbalanced fertilizer use (especially nitrogen-heavy without organic manure) as a major cause of SOC decline alongside climate change, not a minor factor.

Q5:

With reference to the Global Burden of Disease (GBD) 2023 study on Chronic Kidney Disease (CKD), consider the following statements:

1.   India recorded the second-highest number of CKD cases globally, after China.

2.   CKD was among the top ten causes of death worldwide in 2023.

3.   CKD accounted for nearly one-fifth of global cardiovascular deaths, ranking above diabetes and obesity.

4.   South Asia recorded one of the highest regional prevalence rates of CKD in the world.

Which of the statements given above are correct?

A: 1 and 2 only

B: 1,2 and 4 only

C: 2 ,3 and 4 only

D: 1, 2, 3 and 4

Show

Answer: A

Explanation:

Statement 1 – Correct: India had 138 million CKD cases, making it the second-highest globally after China (152 million).

Statement 2 – Correct: CKD was the ninth leading cause of death worldwide in 2023, according to The Lancet GBD study.

Statement 3 – Incorrect: CKD contributed to 12% of global cardiovascular deaths, not one-fifth (~20%). However, it did rank ahead of diabetes and obesity as a cause of heart-related mortality.

Statement 4 – Correct: The South Asia region had a ~16% CKD prevalence, one of the highest globally, after North Africa & the Middle East (~18%).
