Correct Answer: (b) 1, 2 and 4 only

Explanation:

Statement 1 is correct: Article 14 of the Paris Agreement establishes the Global Stocktake to periodically assess collective progress towards achieving the Agreement’s purpose and long-term goals. The first GST concluded in 2023, and subsequent stocktakes are scheduled every five years.

Statement 2 is correct: The first GST concluded at COP28 in Dubai in 2023. Its outcome called for tripling renewable energy capacity globally and doubling the global average annual rate of energy-efficiency improvements by 2030. It also called for transitioning away from fossil fuels in energy systems.

Statement 3 is incorrect: NDCs are nationally determined climate commitments. The Paris Agreement creates binding procedural obligations, including preparing, communicating and maintaining successive NDCs. However, it does not impose uniform emission-reduction targets on all countries or make achievement of each NDC target legally binding.

Statement 4 is correct: Article 2 of the Paris Agreement establishes the objective of keeping warming well below 2°C while pursuing efforts to limit it to 1.5°C above pre-industrial levels.

Explanation:

Statement 1 is correct: UNEP was established by the UN General Assembly in December 1972 following the Stockholm Conference. Its headquarters is located in Nairobi, Kenya.

Statement 3 is correct: The IPCC was established in 1988 by UNEP and WMO. It assesses scientific knowledge relating to climate change, its impacts, future risks and response options. It does not conduct original scientific research.

Statement 4 is incorrect: The GEF is not exclusively associated with the Paris Agreement. It serves as a financial mechanism for several multilateral environmental agreements, including the UNFCCC and the Convention on Biological Diversity.

Correct Answer: (c) 1, 2 and 3 only

Explanation:

Statement 1 is correct: The Visegrad Group is a regional cooperation framework comprising Poland, Hungary, the Czech Republic and Slovakia. It was established in 1991 to strengthen cooperation among Central European countries.

Statement 2 is correct: All four V4 countries are members of the European Union and NATO. However, they do not all use the euro as their national currency.

Statement 3 is correct: Poland lies along the southern coast of the Baltic Sea. Hungary is landlocked and shares borders with countries including Austria, Slovakia, Ukraine, Romania, Serbia, Croatia and Slovenia.

Statement 4 is incorrect: The Danube flows through Budapest, the capital of Hungary, and Bratislava, the capital of Slovakia. However, it does not flow through Warsaw, the capital of Poland, or Prague, the capital of the Czech Republic.

Remember for Prelims:

Explanation:

Statement 1 is correct: Agrivoltaics combines agricultural cultivation and solar power generation on the same land. Depending on panel design, spacing and crop characteristics, the arrangement can support electricity generation while retaining agricultural productivity.

Statement 2 is incorrect: PM-KUSUM is implemented by the Ministry of New and Renewable Energy (MNRE), not the Ministry of Agriculture and Farmers Welfare.

Statement 3 is correct: Component A supports the installation of decentralised, grid-connected renewable energy power plants, generally with capacities ranging from 500 kW to 2 MW.

Statement 4 is correct: Component C provides for the solarisation of grid-connected agricultural pumps, including individual pump solarisation and feeder-level solarisation.

Remember for Prelims:

PM-KUSUM: Pradhan Mantri Kisan Urja Suraksha evam Utthaan Mahabhiyan

• Launched: 2019.
• Nodal ministry: Ministry of New and Renewable Energy.
• Component A: Decentralised, grid-connected renewable energy power plants.
• Component B: Installation of standalone solar agricultural pumps.
• Component C: Solarisation of grid-connected agricultural pumps.

Agrivoltaics — Important Concepts

• Combines agricultural production with solar electricity generation.
• May reduce soil moisture loss through partial shading in suitable conditions.
• Can diversify farmers’ income through electricity generation.
• Requires appropriate crop selection, panel height, spacing and agricultural management.
• Is distinct from conventional ground-mounted solar projects that displace cultivation.

Correct Answer: (a) 1, 2 and 4 only

Explanation:

Statement 1 is correct: Mars has two small, irregularly shaped natural satellites, Phobos and Deimos. Both were discovered by American astronomer Asaph Hall in 1877.

Statement 2 is correct: Phobos completes one revolution around Mars in approximately 7 hours and 39 minutes, whereas Mars takes approximately 24 hours and 37 minutes to rotate once. Consequently, Phobos orbits Mars faster than the planet rotates.

Statement 3 is incorrect: Phobos is both larger and closer to Mars than Deimos. Deimos is the smaller and more distant satellite.

Statement 4 is correct: The MMX mission, developed by the Japan Aerospace Exploration Agency (JAXA), aims to investigate the Martian moons and return samples collected from Phobos to Earth. It is designed to improve understanding of the moons’ origins and the evolution of the Martian system.
