Mega Quiz Correct Answer with Explanation 1.Which of the following characteristics allows cruise missiles used in modern military operations to evade radar detection? A. Their ability to travel along ballistic trajectories outside the atmosphere B. Their capability to fly at low altitudes following terrain contours C. Their dependence on satellite-based navigation systems D. Their use of nuclear propulsion systems Answer: B Explanation Option A is incorrect: Ballistic missiles follow high-altitude trajectories and are easier to detect. Option B is correct: Cruise missiles often fly very close to the ground using terrain-hugging flight paths, reducing radar detection because radar systems are limited by the curvature of Earth and ground clutter. Option C is incorrect: Satellite navigation assists accuracy but does not itself reduce radar detection. Option D is incorrect: Cruise missiles typically use jet engines, not nuclear propulsion. 2.With reference to Nucleic Acid Testing (NAT) used in blood screening, consider the following statements: It detects the presence of pathogens by identifying their genetic material. It can detect infections earlier than antibody-based diagnostic methods. Which of the statements given above is/are correct? A. 1 only B. 2 only C. Both 1 and 2 D. Neither 1 nor 2 Answer: C Explanation Statement 1 is correct: NAT detects DNA or RNA sequences of pathogens, making it a molecular diagnostic technique. Statement 2 is correct: Since NAT detects viral genetic material before the immune system produces antibodies, it reduces the diagnostic window period, improving blood transfusion safety. 3. With reference to the Durand Line, consider the following statements: It was demarcated during the British colonial period in the Indian subcontinent. It separates Afghanistan and Pakistan. It is internationally recognized by Afghanistan as a permanent border. 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: The Durand Line was drawn in 1893 between British India and Afghanistan. Statement 2 is correct: Today it forms the border between Pakistan and Afghanistan. Statement 3 is incorrect: Afghanistan has historically disputed the Durand Line, not fully recognizing it as a permanent border. 4. With reference to Sikkim’s organic agriculture initiative, consider the following statements: Sikkim became the first fully organic state in India in 2016. The FAO honoured Sikkim with the Future Policy Gold Award for its organic policies. Organic certification for exports from Sikkim is handled by APEDA. Which of the statements given above 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: In 2016, Sikkim declared itself India’s first fully organic state. Statement 2 is correct: In 2018, FAO awarded Sikkim the Future Policy Gold Award. Statement 3 is correct: Organic export certification is managed through APEDA’s system. 5. Consider the following statements: Assertion (A): A total lunar eclipse can be observed from a much larger portion of Earth compared to a solar eclipse. Reason (R): Earth’s shadow at the distance of the Moon is significantly larger than the Moon’s shadow on Earth. A. Both A and R are correct and R explains A B. Both A and R are correct but R does not explain A C. A is correct but R is incorrect D. A is incorrect but R is correct Answer: A Explanation Assertion is correct: Lunar eclipses are visible from any location on Earth where the Moon is above the horizon, covering nearly half of Earth. Reason is correct: Earth’s umbral shadow is much larger than the Moon, allowing the Moon to remain inside the shadow for a longer period and making the eclipse visible across a large region. Reason correctly explains the assertion.
