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.

Problem: Question: When was the American Hockey League founded? Passage 1:On December 12, 2008, the Capitals were preparing to host the Ottawa Senators. During the morning skate, José Théodore suffered a hip flexor injury, forcing the Capitals to recall Semyon Varlamov from their American Hockey League (AHL) affiliate, the Hershey Bears. However, Varlamov was with the Bears in San Antonio, Texas and was unable to make it to Washington in time to start the game as the backup goaltender. As a result, the Capitals were forced to dress three goaltenders, signing Leonhardt, the team's website producer, to an amateur tryout contract before the game to back up Brent Johnson until the arrival of Varlamov. Because of his experience in NCAA Division III ice hockey with the State University of New York at Oswego and Neumann College, as well as the Kitchener Dutchmen of the GOJHL, Leonhardt had previously participated in on-ice practice sessions with the Capitals, filling in when an additional goaltender was needed. Varlamov arrived 9:03 into the first period and replaced Leonhardt as Johnson's backup for the remainder of the game. Had Leonhardt played in the game, he would have tied Ben Bishop as the tallest goalie in NHL history. He did not receive any pay for his contract. These bizarre circumstances were remarkably similar to those the Vancouver Canucks faced on December 9, 2003, when starting goaltender Dan Cloutier suffered a groin injury during the morning skate, forcing the Canucks to sign University of British Columbia goaltender Chris Levesque to an amateur tryout contract.
 Passage 2:UK disc jockeys Trevor Fung, Paul Oakenfold, and Danny Rampling are commonly credited with having "popularized" Balearic beat, specially in the UK. In 1987, after a holiday in Ibiza, Oakenfold and his friends Trevor Fung and Ian St. Paul returned to London, where they unsuccessfully tried to establish a nightclub called the Funhouse in the Balearic style. Returning to Ibiza during the summer of 1987, Oakenfold rented a villa where he hosted a number of his DJ friends, including Danny Rampling, Johnny Walker, and Nicky Holloway. Returning to London after the summer, Oakenfold reintroduced the Balearic style at a South London nightclub called the Project Club. The club initially attracted those who had visited Ibiza and who were familiar with the Balearic concept. Fueled by their use of Ecstasy and an emerging fashion style based on baggy clothes and bright colors, these Ibiza veterans were responsible for propagating the Balearic subculture within the evolving UK rave scene. In 1988, Oakenfold established a second outlet for Balearic beat, a Monday night event called Spectrum, which is credited with exposing the Balearic concept to a wider audience. It was 1988 when Balearic beat was first noticed in the U.S., according to Dance Music Report magazine. Jose Padilla, is an Ibizan DJ best known for his residency at Café del Mar. Also Jon Sa Trinxa, a british DJ and Producer best known for the longest residency on Salinas Beach at Sa Trinxa defines his style as being Balearic Music.

On 7 November 2007 in UEFA Champions League home game against Besiktas in the Group Stage, Benayoun scored a hat trick in Liverpool's 8–0 win against the Istanbul team. Benayoun ended a successful first season having played 48 games scoring 11 goals in the process, including four league goals against Wigan Athletic, Portsmouth, Aston Villa, and Birmingham City.
