Answer: B
Explanation:
● Statement 1 is incorrect: Undersea Earthquakes is the most common cause of tsunamis. It occurs when tectonic plates suddenly shift, causing vertical displacement of water. It is typically associated with subduction zones, where one tectonic plate slides beneath another. However, tsunamis can occur at divergent plate boundaries too, though they are most commonly caused by earthquakes at convergent boundaries. These can happen at divergent plate boundaries, transform plate boundaries, or even within a single tectonic plate.
● Statement 2 is correct: Volcanic explosions or the collapse of underwater volcanoes can displace large volumes of water and result in Tsunami. Submarine landslides (underwater) or coastal landslides can create tsunamis. Example: The Lituya Bay tsunami (1958) was triggered by a massive landslide. Large meteors striking the ocean can generate tsunamis due to the sudden displacement of water.
● Statement 3 is correct: Tsunamis happen most frequently in the Pacific Ocean because of the many large earthquakes associated with subduction zones along the margins of the Pacific Ocean basin, which is called the “Ring of Fire”. Ninety percent of the world’s earthquakes occur along the Ring of Fire.

Answer: C

Explanation: Quantum computing is a cutting-edge technology that uses the principles of quantum mechanics to solve problems too complex for traditional computers.

• Statement 1 is correct: Superpositionrefers to the ability of a quantum system to be in multiple states at once. Superposition can apply to any state that a quantum system might be in. This includes location, electron spin or energy level.
• Statement 2 is incorrect: Entanglement is a physical phenomenon where two or more particles are linked, so that the state of one particle is directly related to the state of the other. Quantum entanglementoccurs when two systems link so closely that knowledge about one gives you immediate knowledge about the other. Quantum fidelity is the measure or precision of how close two quantum states are to each other.

Statement 3 is correct: Quantum coherence is a fundamental property of quantum mechanics that describes a quantum system’s ability to maintain its quantum states and generate interference patterns. It is the ability of a quantum system to maintain a well-defined phase relationship between different states in a superposition. It is essential for quantum computation and quantum information processing. It’s also a necessary condition for entanglement and other types of quantum correlations.

Answer: A

Explanation:

• Pair 1 is incorrectly matched: Paktika is one of the 34 provinces of Afghanistan, located in the eastern part of the country. The ethnic groups of the province are Pashtun, Tajik, Arab, Pashai, and other various minority groups.Pakistan has recently bombed Afghanistan’s Paktika resulting in 46 dead.
• Pair 2 is incorrectly matched: The city of Port-Au-Prince, founded in the 18th century, is the capital of Haiti.More than 5,000 people have been reported killed so far this year in Haiti, the majority of them victims by gangs that control 85% of the capital. Political turmoil, civil unrest, violence, crippling poverty and other natural disasters are jeopardizing the well-being and future of Haiti’s children.

Pair 3 is correctly matched: Beqaa is a governorate and  fertile valley in eastern Lebanon, between the Lebanon and Anti-Lebanon Mountains. It’s Lebanon’s most important farming region and is known as the “bread basket of Lebanon. It is a target of Israeli airstrikes, along with the towns of Rachaiya, Hasbaiya, and Khiam.

Answer: A

Explanation: Critical minerals are mineral resources, both primary and processed, that are essential inputs in modern technologies, economies, and national security.They are characterized by the risk of supply chain disruption due to non-availability and price volatility.

• Statement 1 is correct while Statements 2 are incorrect: China is the world’s largest producer of many critical minerals, including: Gallium: China produced 98.18% of the world’s gallium in 2023 , Magnesium: China produced 88% of the world’s magnesium in 2023, Tungsten: China produced 80.8% of the world’s tungsten in 2023 and Rare earth metals: China produces about two-thirds of the world’s rare earth metals accounting for nearly 70% of global production in 2023. An in-depth examination of import data of 30 critical minerals spanning 2019 to 2024 reveals India’s acute vulnerability to Chinese supplies, particularly for six critical minerals where dependency exceeds 40%. India’s Critical Minerals Import Dependency (2019-2024) on China:
• Bismuth (85.6%): Used in pharmaceuticals and chemicals; China controls 80% of global refinery production.
• Lithium (82%): Crucial for EV batteries; China refines 58% of global supply.
• Silicon (76%): Key for semiconductors and solar panels; advanced processing technology required.

Titanium (50.6%): Vital for aerospace and defence; diversification exists but switching costs are high.

Answer: A

Explanation:

• Statement 1 is not correct: Eklavya Model Residential School (EMRS) is a Government of India scheme for model residential school for Indian tribals (Scheduled Tribes) across India. It is one of the flagship interventions of the Ministry of Tribal Affairs, Government of India and was introduced in the year 1997-98 to ensure tribal students get access to quality education in the remote tribal areas.
• Statement 2 is not correct: Earlier EMRS was a component under Article 275(1) of the Constitution. Under the new scheme, the Government decided to establish one EMRS in every block having more than 50% ST population and at least 20,000 tribal persons (as per census 2011).

Statement 3 is correct: The provision to introduce a 5% sub-quota for Particularly Vulnerable Tribal Groups (PVTG) students in admissions to EMRSs was introduced after the administration of the schools was centralised by setting up the National Education Society for Tribal Students in 2019.
