Given the task definition, example input & output, solve the new input case.
In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.
Example: Question: When did the operation during which the 704th dropped supplies to allied troops near Nijmegen begin? Passage 1: The group was occasionally diverted from strategic missions to carry out air support and interdiction missions. It supported Operation Overlord, the invasion of Normandy by attacking transportation targets, including bridges, along with airfields and strong points in France. On D Day, the squadron and the rest of the 446th Group led the first heavy bomber mission of the day. The 446th aided ground forces at Caen and Saint-Lô during July by hitting bridges, gun batteries, and enemy troops. During Operation Market Garden, the attempt to seize a bridgehead across the Rhine in the Netherlands, the 704th dropped supplies to allied troops near Nijmegen. It struck lines of communications during the Battle of the Bulge. During Operation Varsity in March 1945, it supplied ground and airborne troops near Wesel. The squadron flew its last combat mission on 25 April 1945 against Salzburg, Austria. The group had flown 273 missions and had lost 58 aircraft during the war,
. Passage 2: John Ford (1894–1973) was an American film director whose career spanned from 1913 to 1971. During this time he directed more than 140 films. Born in Maine, Ford entered the filmmaking industry shortly after graduating from high school with the help of his older brother, Francis Ford, who had established himself as a leading man and director for Universal Studios. After working as an actor, assistant director, stuntman, and prop man – often for his brother – Universal gave Ford the opportunity to direct in 1917. Initially working in short films, he quickly moved into features, largely with Harry Carey as his star. In 1920 Ford left Universal and began working for the Fox Film Corporation. During the next ten years he directed more than 30 films, including the westerns The Iron Horse (1924) and 3 Bad Men (1926), both starring George O'Brien, the war drama Four Sons and the Irish romantic drama Hangman's House (both 1928 and both starring Victor McLaglen). In the same year of these last two films, Ford directed his first all-talking film, the short Napoleon's Barber. The following year he directed his first all-talking feature, The Black Watch.
. Passage 3: Since the late 1970s, the central part of NYU is its Washington Square campus in the heart of Greenwich Village. Despite being public property, and expanding the Fifth Avenue axis into Washington Square Park, the Washington Square Arch is the unofficial symbol of NYU. Until 2008, NYU's commencement ceremony was held in Washington Square Park. However, due to space constraints, ceremonies are now held at the Yankee Stadium. Important facilities at Washington Square are the Elmer Holmes Bobst Library, designed by Philip Johnson and Richard Foster, who also designed several other structures, such as Tisch Hall, Meyer Hall, and the Hagop Kevorkian Center. When designing these buildings Johnson and Foster also set up a master plan for a complete redesign of the NYU Washington Square campus. However, it was never implemented. Other historic buildings include the Silver Center (formerly known as "Main building"); the Brown Building of Science; Judson Hall, which houses the King Juan Carlos I of Spain Center; Vanderbilt Hall, the historic townhouse row on Washington Square North; The Grey Art Gallery at 100 Washington Square East, housing the New York University art collection and featuring museum quality exhibitions; the Kaufman Management Center; and the Torch Club – the NYU dining and club facility for alumni, faculty, and administrators. Just a block south of Washington Square is NYU's Washington Square Village, housing graduate students and junior and senior faculty residences in the Silver Towers, designed by I. M. Pei, where an enlargement of Picasso's sculpture Bust of Sylvette (1934) is displayed.

New input case for you: Question: In what year was the city founded where the WKY Television System is based? Passage 1:The WKY Television System, based in Oklahoma City and the forerunner to Gaylord Broadcasting, bought the station in 1966 and changed its call letters to WVTV. The new owners also built new studio facilities at the corner of North 35th Street and Capital Drive. This started the station on its path to becoming one of the most popular independent stations in the country, with strong local programming such as The Bowling Game (which would eventually be syndicated across the Midwest), along with a strong slate of syndicated programs such as cartoons, classic off-network sitcoms, more recent sitcoms, drama series, sports, and movies. Like its Gaylord stablemates, channel 18 focused on programming geared towards rural and suburban audiences located in Milwaukee's outer ring, opposed to the more urban fare presented by Milwaukee's other stations. Longtime staples on WVTV included Hee Haw (which was produced by sister division Gaylord Entertainment), The Lawrence Welk Show as well as syndicated reruns of Green Acres and The Andy Griffith Show. The station also aired All Star Wrestling during the 1970s and 1980s.
 Passage 2:An early recorded use of foreign auxiliaries dates back to Ancient Egypt, the thirteenth century BC, when Pharaoh Ramesses II used 11,000 mercenaries during his battles. A long established foreign corps in the Egyptian forces were the Medjay—a generic term given to tribal scouts and light infantry recruited from Nubia serving from the late period of the Old Kingdom through that of the New Kingdom. Other warriors recruited from outside the borders of Egypt included Libyan, Syrian and Canaanite contingents under the New Kingdom and Sherdens from Sardinia who appear in their distinctive horned helmets on wall paintings as body guards for Ramesses II. Celtic mercenaries were greatly employed in the Greek world (leading to the sack of Delphi and the Celtic settlement of Galatia). The Greek rulers of Ptolemaic Egypt, too, used Celtic mercenaries. Carthage was unique for relying primarily on mercenaries to fight its wars, particularly Gaul and Spanish mercenaries.
 Passage 3:Its location at the foot of the historic Pierre Pertuis pass (in operation since the Roman era) made the villages an important stopping point and transportation hub. The Petinesca Roman road ran to the east of Sonceboz before it crossed the Jura mountains. The ruins of a 4th-century Roman settlement have been discovered at the Le Châtillon ridge. After the collapse of the Roman Empire, a medieval settlement developed over the Roman settlement. In 999 Moutier-Grandval Abbey gave the local farms and the Summavallis chapel to the Prince-Bishop of Basel. The Prince-Bishop assigned Moutier-Grandval Abbey to administer the village as the bailiff and the parish priest (placing the Abbey over the secular and spiritual needs of the village). This organization continued until Sonceboz and Sombeval accepted the Protestant Reformation in 1530. After the Reformation, the villages were under the secular administration of Erguel. After the 1797 French victory and the Treaty of Campo Formio, Sonceboz-Sombeval became part of the French Département of Mont-Terrible. Three years later, in 1800 it became part of the Département of Haut-Rhin. After Napoleon's defeat and the Congress of Vienna, Sonceboz-Sombeval was assigned to the Canton of Bern in 1815.
