Input: Read this: The development of flattop vessels produced the first large fleet ships. In 1918, HMS Argus became the world's first carrier capable of launching and recovering naval aircraft. As a result of the Washington Naval Treaty of 1922, which limited the construction of new heavy surface combat ships, most early aircraft carriers were conversions of ships that were laid down (or had served) as different ship types: cargo ships, cruisers, battlecruisers, or battleships. These conversions gave rise to the Lexington-class aircraft carriers (1927), Akagi and Courageous class. Specialist carrier evolution was well underway, with several navies ordering and building warships that were purposefully designed to function as aircraft carriers by the mid-1920s, resulting in the commissioning of ships such as Hosho (1922), HMS Hermes (1924), and Bearn (1927). During World War II, these ships would become known as fleet carriers.[citation needed]
Question: What was the world's first carrier capable of launching and recovering civilian aircraft?

Input: Read this: The first Code of Canon Law, 1917, was mostly for the Roman Rite, with limited application to the Eastern Churches. After the Second Vatican Council, (1962 - 1965), another edition was published specifically for the Roman Rite in 1983. Most recently, 1990, the Vatican produced the Code of Canons of the Eastern Churches which became the 1st code of Eastern Catholic Canon Law.
Question: When was the first Code produced for Eastern Churches?

Output: 1990

Input: Read this: The major agricultural product is rice, which covers about 60% of the country's total cultivated land area. Rice accounts for 97% of total food grain production by weight. Through collaboration with the International Rice Research Institute 52 modern rice varieties were released in the country between 1966 and 1997, helping increase national rice production to 14 million tons in 1987 and to 19 million tons in 1996. By 1988, modern varieties were planted on half of the country's ricelands, including 98 percent of the irrigated areas. In 2008 rice production was estimated at 50 million tons.
Question: How many novel types of this crop did Burma develop as of 1997 ?

Output: 52 modern rice varieties

Input: Read this: 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 aircraft is used by the US Air Demonstration group The Thunderbirds?

Output:
F-16
