Q: Passage: Varaha Cave Temple (also Adivaraha Cave Temple) is a rock-cut cave temple located at Mamallapuram, on the Coromandel Coast of the Bay of Bengal in Kancheepuram District in Tamil Nadu, India. It is part of the hill top village, which is to the north of the main Mahabalipurm sites of rathas and the Shore Temple. It is an example of Indian rock-cut architecture dating from the late 7th century. The temple is one of the finest testimonial to the ancient Vishwakarma Sthapathis, of rock-cur cave architecture, out of many such caves also called mandapas. Part of the Group of Monuments at Mahabalipuram, the temple is a UNESCO World Heritage Site as inscribed in 1984 under criteria i, ii, iii and iv. The most prominent sculpture in the cave is that of Lord Vishnu in the incarnated form of a Varaha or boar lifting Bhudevi, the mother earth goddess from the sea. Also carved are many mythical figures.

Q: Passage: Strategic Air Command was formed by the United States Air Force after World War II to provide an active defense against any surprise attack by the Soviet Union. Though it had been an ally against Germany and Japan during World War II, by 1948 the Soviet Union showed a propensity to instigate problems with Britain, France and the United States. In August 1949, the Soviet Union detonated its first nuclear weapon and by the early 1950s had detonated a hydrogen bomb. The war of words between the two superpowers escalated during 1950s and 1960s into a nuclear arms race. By 1970 the United States was using a "Triad Defense System" composed of nuclear submarines armed with nuclear missiles, land based intercontinental ballistic missiles with nuclear warheads and bombers capable of delivering hydrogen bombs on enemy targets. The Boeing B-52 Stratofortress bomber had been designed in the early 1950s by Boeing Aircraft Company to give the United States Air Force the capability of delivering nuclear weapons far inside the territory of Soviet Russia. The planes were to fly at high altitude with enough fuel to hit their target. In May 1960, the Soviet Union made known its capability to shoot such high altitude planes out of the sky by using a surface to air missile to strike CIA pilot Francis Gary Powers' U-2 spy plane over Russian territory. From that point on, the high-altitude B-52 had to be modified to conduct missions at low level, something it was not intended to be.

Q: Passage: Joining the Battle of Hürtgen Forest, the division moved into defensive positions in the vicinity of Wuustwezel, Belgium on 23 October 1944. The Timberwolves were then assigned to British Field Marshal Bernard Montgomery's Anglo-Canadian 21st Army Group under the British I Corps, along with the U.S. 7th Armored Division, in order to clear out the Scheldt Estuary and open the port of Antwerp.
