Q1:
Consider the following statements regarding the Hayli Gubbi Volcano, which recently erupted for the first time in recorded history: Which of the statements given above is/are correct?
A: 1 and 2 only
B: 1 and 3 only
C: 2 and 3 only
D: 1, 2, and 3
Answer: D
Explanation:
Statement 1 is correct.
Hayli Gubbi is a shield volcano in northeastern Ethiopia. Shield volcanoes are broad, gently sloping structures formed by fluid lava flows. It lies in the Afar Rift, which is a segment of the East African Rift System, one of the most tectonically active regions in the world.
Statement 2 is correct.
The Afar Rift forms a triple junction where the Nubian Plate, Somali Plate, and Arabian Plate diverge. This tectonic configuration makes the region highly unstable and prone to volcanic activity.
Statement 3 is correct.
The November 2025 eruption produced ash plumes reaching 14 km into the atmosphere, which is within the lower stratosphere. The ash cloud dispersed across the Red Sea, affecting Yemen, Oman, Pakistan, and northern India.
Q2:
With reference to volcanic formation and global volcanic activity, consider the following pairs: Volcanic Feature / Type Characteristic / Location 1. Shield Volcano Formed by low-viscosity lava; broad and gently sloping 2. Composite Volcano Typically found at divergent plate boundaries 3. Hotspot Volcano Results from mantle plumes independent of plate boundaries 4. Lava Dome Formed from highly viscous lava near the vent Which of the above pairs is/are correctly matched?
A: 1 and 2 only
B: 1,3 and 4 only
C: 1, 2 and 3 only
D: 1, 2, 3 and 4
Answer: B
Explanation:
Pair 1 is correctly matched.
Shield volcanoes (e.g., Mauna Loa) form from fluid, low-viscosity lava, creating broad and gently sloping landforms—just like Hayli Gubbi.
Pair 2 is incorrectly matched.
Composite or stratovolcanoes (e.g., Mount Fuji, Vesuvius) generally occur at convergent plate boundaries, not divergent ones. They alternate between lava flows and explosive eruptions.
Pair 3 is correctly matched.
Hotspot volcanoes form due to mantle plumes, independent of tectonic plate boundaries (e.g., Hawaii, Yellowstone).
Pair 4 is correctly matched.
Lava domes form when viscous magma accumulates near the vent, leading to a dome-like structure (e.g., dome formed after Mount St. Helens eruption).
Q3:
With reference to malaria and global malaria vaccines, consider the following pairs: Vaccine / Pathogen Correct Description 1. R21/Matrix-M Developed by University of Oxford and Serum Institute of India 2. RTS,S/AS01 Uses Novavax’s Matrix-M adjuvant 3. Plasmodium falciparum Most lethal malaria parasite, dominant in Africa 4. Plasmodium vivax Dominant mostly in sub-Saharan Africa Which of the above pairs are correctly matched?
A: 1 and 2 only
B: 1,3 and 4 only
C: 1 and 3 only
D: 1, 2, 3 and 4
Answer: C
Explanation:
Pair 1 is correctly matched.
R21/Matrix-M was co-developed by the University of Oxford and the Serum Institute of India, and uses the Matrix-M adjuvant from Novavax.
Pair 2 is incorrectly matched.
RTS,S/AS01, developed by GSK and PATH, does not use Matrix-M. It uses the AS01 adjuvant system.
Pair 3 is correctly matched.
P. falciparum is the deadliest and the most prevalent in sub-Saharan Africa, causing the majority of malaria deaths.
Pair 4 is incorrectly matched.
P. vivax is dominant outside sub-Saharan Africa, especially in Asia and the Americas, not in Africa.
Q4:
With reference to the Highly Agile Modular Munition Extended Range (HAMMER) weapon system, consider the following statements: 1. HAMMER is a modular air-to-ground weapon capable of carrying warheads of up to 1000 kg. 2. The weapon has a maximum range of about 150 km, giving it long-range deep-strike capability. 3. It is designed to function in all-weather conditions and is resistant to electronic jamming. 4. It is compatible only with Rafale aircraft since it was originally developed in France. How many of the above statements are correct?
A: Only one
B: Only two
C: Only three
D: All four
Answer: C
Explanation:
Statement 1 is correct.
HAMMER is modular and supports multiple warhead sizes: 250 kg, 500 kg, and 1000 kg. This flexibility allows it to be tailored to mission needs.
Statement 2 is incorrect.
HAMMER has a range of up to ~70 km, not 150 km. It is designed as a standoff weapon, but not a long-range deep-strike system.
Statement 3 is correct.
The weapon is all-weather, highly accurate, and resistant to jamming, making it suitable for low-altitude launches and rugged operational conditions.
Statement 4 is incorrect.
Although initially developed for France’s Rafale, HAMMER is compatible with multiple platforms, including India’s Tejas Light Combat Aircraft.
Q5:
With reference to Article 240 of the Constitution, consider the following statements: 1. Article 240 empowers the President to make regulations for certain Union Territories, which have the same force as Acts of Parliament. 2. Presidential regulations under Article 240 can amend or repeal any existing Central law as applicable to that Union Territory. 3. Chandigarh is currently governed under Article 240. 4. Puducherry always falls under Article 240 since it is a Union Territory with a legislature. How many of the above statements are correct?
A: Only one
B: Only two
C: Only three
D: All four
Answer: B
Explanation:
Statement 1 is correct.
Article 240 empowers the President to make regulations for specified UTs such as Andaman & Nicobar Islands, Lakshadweep, and Dadra & Nagar Haveli & Daman & Diu.
These regulations carry the same legal force as Acts of Parliament.
Statement 2 is correct.
Presidential regulations under Article 240 can amend or repeal any existing parliamentary law as applicable to that UT—an unusually strong executive law-making power.
Statement 3 is incorrect.
Chandigarh is not currently governed under Article 240.
It is administered by the Governor of Punjab, who serves as its Administrator.
Reports suggested that the 131st Amendment Bill might bring Chandigarh under Article 240, but no such change has occurred.
Statement 4 is incorrect.
Puducherry does not always fall under Article 240.
Article 239A governs its elected legislature.
Article 240 applies only when the assembly is suspended or dissolved.
