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.

Let me give you an 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.

Question: What year was British United Airways founded? Passage 1:Jersey Airlines was an early post-World War II private, independent British airline formed in 1948. In 1952, the airline operated its first scheduled service. Four years later, British European Airways (BEA) took a 25% minority stake in Jersey Airlines and made it an "associate". In June 1958, a Jersey Airlines de Havilland Heron became the first commercial airliner to arrive at the newly reconstructed Gatwick Airport. In 1960, Jersey Airlines ordered four state-of-the-art Handley Page Dart Herald 200 series turboprops. By 1962, BEA had sold its 25% minority holding in Jersey Airlines. The same year, Jersey Airlines became part of the British United Airways (BUA) group of companies. In August 1963, Jersey Airlines changed its trading name to British United (C.I.) Airways. Following the BUA group's 1967/8 reorganisation, BUA (C.I.) was absorbed into British United Island Airways (BUIA) in November 1968.
 Passage 2:After its success in Australia, Wolfmother was later released internationally in early 2006 – on 24 April in the UK, where it reached number 25 on the UK Albums Chart, and on 2 May in the US, where it reached number 22 on the Billboard 200. A number of singles were released from the album, including "Woman" which reached number 34 in Australia, number 31 on the UK Singles Chart, and number 7 on the US Billboard Mainstream Rock chart. The song later won the Grammy Award for Best Hard Rock Performance at the 49th Annual Grammy Awards, the nomination for which Heskett had previously described as "an honour". The final single from the album, "Joker & the Thief", later reached the top ten in Australia. The subsequent worldwide tour included appearances at festivals such as Fuji Rock in Tokyo, Japan, the inaugural Virgin Festival, and Reading and Leeds Festivals in the UK. On 14 November 2006, the band performed a cover version of "Communication Breakdown" by English hard rock band Led Zeppelin as a tribute to the band for their induction into the UK Music Hall of Fame.
 Passage 3:Publicist Jolene (Denise Richards) has a tense relationship with rock musician Hank (James Stevenson), who is planning to marry journalist Rose (Lauren German). As the lead singer of the band Modern Apes, Hank performs "mocking [and] self-congratulatory" versions of Barry Manilow's music. According to Tatiana Morales of CBS News, people compared Jolene to Amanda Woodward from Melrose Place. Muir characterized Jolene as a maneater, and Phil Gallo of Variety viewed her as "a devilish character with a dark soul". On the other hand, Shandy Casteel of PopMatters described Rose as the girl next door. David Bianculli of the New York Daily News cited her as the show's lead character. In the pilot episode, Rose receives the ashes of her ex-boyfriend Billy (Dylan Bruno), but it is revealed he is alive when he re-enters the characters' lives. Jolene believes that Rose had ruined her relationship with Billy, and responds by plotting to take Hank as "a means to nasty retaliation". As part of the show's comedy, Rose imagines people singing pop music to her.
