Metals come under which class of fire?

The correct answer is A, Boston. The Freedom Trail is a 2.5-mile red brick path laid out in Boston, Massachusetts, in 1951, linking sixteen sites connected with the American Revolution. Walkers pass the Massachusetts State House, the Old South Meeting House where the Boston Tea Party was planned, the spot of the Boston Massacre, Paul Revere's house and the Bunker Hill Monument, and the walk ends at the warship USS Constitution. Boston was the centre of colonial protest against British taxes, which is why so much of the revolution's story sits inside one walkable city. B is wrong because Memphis in Tennessee is known for Beale Street and the civil rights museum at the Lorraine Motel. C is wrong because Denver in Colorado is a much later city of the American West. D is wrong because Connecticut is a state, not a city. Exam tip: Freedom Trail, Boston Tea Party and Boston Massacre all point to the same city.

The correct answer is B, Sardar Vallabhbhai Patel. The Statue of Unity stands on Sadhu Bet, an island in the Narmada near the Sardar Sarovar Dam in the Narmada district of Gujarat, and it shows Sardar Vallabhbhai Patel, independent India's first Deputy Prime Minister and Home Minister, who brought the princely states into the Union. The statue is 182 metres tall, a height chosen to match the number of seats in the Gujarat Assembly, and it was unveiled on 31 October 2018, Patel's birth anniversary. Ram V. Sutar designed it, and iron collected from farmers across the country went into the work. A is wrong because M. K. Gandhi has no statue of this scale. C is wrong because Vinoba Bhave, who led the Bhoodan movement, is not its subject. D is wrong because Dr B. R. Ambedkar is honoured by other memorials, not by this statue. Exam tip: Statue of Unity — 182 m, Sardar Patel, on the Narmada in Gujarat, unveiled 31 October 2018.

The correct answer is B, Odisha. The Integrated Test Range of the DRDO lies at Chandipur on the Balasore coast of Odisha, and its launch complex on Dr Abdul Kalam Island, earlier called Wheeler Island, off the same coast is used for longer range tests. Option A is wrong because Andhra Pradesh has Sriharikota, the Satish Dhawan Space Centre, which belongs to ISRO and launches satellites rather than testing military missiles. Option C is wrong because Tamil Nadu has the Thumba equatorial rocket station nearby in Kerala and a propulsion complex at Mahendragiri, but not the missile test range. Option D is wrong because Gujarat has no missile test range of this kind. Keep Chandipur for missiles and Sriharikota for satellite launches separate, because both appear in the same options.

The correct answer is D, Narendra Modi. The Prime Minister commissioned INS Vikrant at Kochi on 2 September 2022; built by Cochin Shipyard, it is the first aircraft carrier designed and built in India and it carries the name of the older Vikrant that served in the 1971 war. At the same ceremony the new naval ensign was unveiled. Option A is wrong because Rajnath Singh, as Defence Minister, has commissioned and launched other warships but not this carrier. Option B is wrong because Amit Shah holds the Home portfolio, which deals with the central armed police forces rather than the Navy. Option C is wrong because Jyotiraditya Scindia held the civil aviation portfolio and had no role in the commissioning. India's other carrier is INS Vikramaditya, rebuilt from the Russian Admiral Gorshkov.

The correct answer is B, Ashoka Chakra. India keeps two ladders of gallantry awards. Away from the battlefield the order is Ashoka Chakra, Kirti Chakra and Shaurya Chakra, so Ashoka Chakra stands highest in peacetime. Option A is wrong because the Param Vir Chakra is the highest award for gallantry in the face of the enemy, that is in war. Option C is wrong because the Kirti Chakra stands second in the peacetime ladder, below the Ashoka Chakra. Option D is wrong because the Maha Vir Chakra is the second highest wartime award, below the Param Vir Chakra and above the Vir Chakra. All six decorations were instituted on 26 January 1950, and the first Param Vir Chakra went posthumously to Major Somnath Sharma in 1947.
