Q1. With reference to the NISAR (NASA-ISRO Synthetic Aperture Radar) Earth-observing satellite mission, consider the following statements:
1. NISAR is a collaborative Earth-observing radar mission developed jointly by NASA and ISRO.
2. It is the first satellite mission to utilize dual-frequency synthetic aperture radar operating in both L-band and S-band frequencies.
3. The satellite operates in a geostationary orbit to provide continuous real-time transmission over the Indian Ocean alone.
Which of the statements given above are correct?
(a) 1 and 3 only
(b) 1 and 2 only
(c) 2 and 3 only
(d) 1, 2, and 3

Answer: (b)
Explanation:
Statement 1 is Correct: The NISAR (NASA-ISRO Synthetic Aperture Radar) mission is a landmark joint collaboration between the National Aeronautics and Space Administration (NASA) of the United States and the Indian Space Research Organisation (ISRO) to map the global land and ice masses with unprecedented detail.
Statement 2 is Correct: NISAR is the first satellite mission to employ dual-frequency synthetic aperture radar (SAR), incorporating an L-band SAR provided by NASA (sensitive to dense vegetation and biomass) and an S-band SAR designed and built by ISRO (optimized for soil moisture, crops, and coastal processes).
Statement 3 is Incorrect: NISAR operates in a sun-synchronous Low Earth Orbit (LEO) at an altitude of approximately 747 kilometers (not geostationary orbit); it maps the entire Earth's land and ice surfaces every 12 days to monitor crustal deformation, glacier retreats, and ecosystem dynamics globally.

Q2. With reference to the Indo-Pacific Economic Framework for Prosperity (IPEF), consider the following statements:
1. IPEF is an economic initiative launched by the United States with partner countries across the Indo-Pacific region.
2. The framework is structured around four pillars: Trade, Supply Chains, Clean Economy, and Fair Economy.
3. India has acceded to the agreements on Supply Chains, Clean Economy, and Fair Economy while maintaining observer status on the Trade pillar.
Which of the statements given above are correct?
(a) 1 and 2 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2, and 3

Answer: (d)
Explanation:
Statement 1 is Correct: The Indo-Pacific Economic Framework for Prosperity (IPEF) was launched in Tokyo in May 2022 by the United States alongside 13 partner nations representing approximately 40 percent of global Gross Domestic Product.
Statement 2 is Correct: Unlike conventional preferential trade agreements that focus on tariff elimination, IPEF is built around four independent policy pillars: Pillar I (Trade), Pillar II (Supply Chain Resilience), Pillar III (Clean Economy), and Pillar IV (Fair Economy - Tax and Anti-Corruption).
Statement 3 is Correct: India actively negotiated and signed the landmark IPEF Supply Chain Agreement, the Clean Economy Agreement, and the Fair Economy Agreement, while opting to maintain observer status on Pillar I (Trade) to protect its domestic policy space regarding labor standards, environment, and data localization.

Q3. Consider the following statements regarding the Joint Sitting of Parliament under Article 108 of the Constitution:
1. A joint sitting of Parliament is summoned by the President to resolve a legislative deadlock between the Lok Sabha and the Rajya Sabha.
2. The joint sitting is presided over by the Speaker of the Lok Sabha, or in their absence, by the Deputy Speaker of the Lok Sabha.
3. A Constitutional Amendment Bill can be referred to a joint sitting if rejected by the Rajya Sabha.
Which of the statements given above are correct?
(a) 1 and 2 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2, and 3

Answer: (a)
Explanation:
Statement 1 is Correct: Under Article 108 of the Constitution, if an ordinary bill passed by one House is rejected by the other House, or the Houses disagree on amendments, or more than six months elapse without passing, the President may notify an intention to summon a joint sitting of both Houses to resolve the legislative deadlock.

Statement 2 is Correct: Article 118(4) provides that the Speaker of the Lok Sabha presides over a joint sitting; in the Speaker's absence, the Deputy Speaker presides, and if the Deputy Speaker is also absent, the Deputy Chairman of the Rajya Sabha presides (the Chairman of the Rajya Sabha / Vice-President never presides because they are not a member of either House).
Statement 3 is Incorrect: The mechanism of joint sitting is applicable only to Ordinary Bills and Financial Bills; it is explicitly not available for Money Bills (where Rajya Sabha has only 14 days' recommendatory power) or Constitutional Amendment Bills under Article 368 (which must be passed separately by each House by a special majority).

Q4. With reference to Ecological Succession and pioneer communities, consider the following statements:
1. Primary ecological succession occurs on newly formed, sterile substrate where no biological community previously existed.
2. Lichens and mosses typically serve as the pioneer species in primary xerarch succession on bare rock surfaces.
3. Secondary ecological succession proceeds much more slowly than primary succession due to the complete lack of organic soil.
Which of the statements given above are correct?
(a) 1 and 3 only
(b) 1 and 2 only
(c) 2 and 3 only
(d) 1, 2, and 3

Answer: (b)
Explanation:
Statement 1 is Correct: Primary succession takes place on barren, newly exposed terrestrial or aquatic sites where no vegetative cover or organic soil layer previously existed, such as newly cooled lava flows, newly formed sand dunes, or retreat zones of glaciers.
Statement 2 is Correct: In primary succession on bare rock (xerarch succession), crustose lichens act as pioneer species by secreting organic acids that weather the mineral rock face, accumulating organic matter and dust that enable hardy mosses and grasses to take root.
Statement 3 is Incorrect: Secondary succession occurs on areas where an established biological community was disturbed or destroyed (e.g., by forest fires, floods, or abandoned agricultural fields) but where biologically viable soil, organic nutrients, and seeds or underground propagules persist; consequently, secondary succession establishes much FASTER than primary succession.

Q5. Consider the following statements regarding the Continental Drift Theory and Plate Tectonics:
1. Alfred Wegener proposed that all continents were once assembled into a single supercontinent called Pangea, surrounded by the ocean Panthalassa.
2. Wegener cited the presence of identical Glossopteris plant fossils across South America, Africa, India, Australia, and Antarctica as evidence of continental drift.
3. Modern plate tectonics asserts that continental masses move across a static, non-convecting liquid outer core.
Which of the statements given above are correct?
(a) 1 only
(b) 2 and 3 only
(c) 1 and 2 only
(d) 1, 2, and 3

Answer: (c)
Explanation:
Statement 1 is Correct: In 1912, German meteorologist Alfred Wegener postulated the Continental Drift Theory, proposing that during the late Paleozoic era, all landmasses formed a singular supercontinent named Pangea ('all earth'), surrounded by an immense universal ocean called Panthalassa ('all water').
Statement 2 is Correct: Wegener provided paleobiological evidence including the widespread distribution of identical fossils of the seed-fern Glossopteris and the reptile Mesosaurus across fragmented continents of Gondwanaland (South America, Africa, Madagascar, India, Australia, and Antarctica), which could not have crossed open oceanic expanses.
Statement 3 is Incorrect: Plate Tectonics theory demonstrates that rigid lithospheric plates (crust and uppermost solid mantle) float and move horizontally over the ductile, semi-fluid asthenosphere in the upper mantle; their motion is driven by thermal convection currents generated by radioactive decay in the mantle (not movement over the liquid outer core).
