Article: Guam lies between 13.2N and 13.7N and between 144.6E and 145.0E, and has an area of 212 square miles (549 km2), making it the 32nd largest island of the United States. It is the southernmost and largest island in the Mariana island chain and is also the largest island in Micronesia. This island chain was created by the colliding Pacific and Philippine Sea tectonic plates. Guam is the closest land mass to the Mariana Trench, a deep subduction zone, that lies beside the island chain to the east. Challenger Deep, the deepest surveyed point in the Oceans, is southwest of Guam at 35,797 feet (10,911 meters) deep. The highest point in Guam is Mount Lamlam at an elevation of 1,334 feet (407 meters).

Question: How many square miles is Guam?
Ans: 212

Article: The first issue was ammunition. Before the war it was recognised that ammunition needed to explode in the air. Both high explosive (HE) and shrapnel were used, mostly the former. Airburst fuses were either igniferious (based on a burning fuse) or mechanical (clockwork). Igniferious fuses were not well suited for anti-aircraft use. The fuse length was determined by time of flight, but the burning rate of the gunpowder was affected by altitude. The British pom-poms had only contact-fused ammunition. Zeppelins, being hydrogen filled balloons, were targets for incendiary shells and the British introduced these with airburst fuses, both shrapnel type-forward projection of incendiary 'pot' and base ejection of an incendiary stream. The British also fitted tracers to their shells for use at night. Smoke shells were also available for some AA guns, these bursts were used as targets during training.

Question: It was understood that ammunition needed to explode where?
Ans: in the air

Article: In 1986, eight years before the launch of Turner Classic Movies, Ted Turner acquired the Metro-Goldwyn-Mayer film studio for $1.5 billion. Concerns over Turner Entertainment's corporate debt load resulted in Turner selling the studio that October back to Kirk Kerkorian, from whom Turner had purchased the studio less than a year before. As part of the deal, Turner Entertainment retained ownership of MGM's library of films released up to May 9, 1986. Turner Broadcasting System was split into two companies; Turner Broadcasting System and Metro-Goldwyn-Mayer and reincorporated as MGM/UA Communications Co.

Question: In what year did Ted Turner buy Metro-Goldwyn-Mayer?
Ans: 1986

Article: The fighter aircraft of the USAF are small, fast, and maneuverable military aircraft primarily used for air-to-air combat. Many of these fighters have secondary ground-attack capabilities, and some are dual-roled as fighter-bombers (e.g., the F-16 Fighting Falcon); the term "fighter" is also sometimes used colloquially for dedicated ground-attack aircraft. Other missions include interception of bombers and other fighters, reconnaissance, and patrol. The F-16 is currently used by the USAF Air Demonstration squadron, the Thunderbirds, while a small number of both man-rated and non-man-rated F-4 Phantom II are retained as QF-4 aircraft for use as Full Scale Aerial Targets (FSAT) or as part of the USAF Heritage Flight program. These extant QF-4 aircraft are being replaced in the FSAT role by early model F-16 aircraft converted to QF-16 configuration. The USAF has 2,025 fighters in service as of September 2012.

Question: What is the name of a type of dual purpose fighter-bomber aircraft used by the US Air Force?
Ans:
F-16 Fighting Falcon
