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: How many members did the Boston Symphony Orchestra have when Lilacs for voice and orchestra was premiered by the group? Passage 1:Whitman's poem appears in the Broadway musical Street Scene (1946) which was the collaboration of composer Kurt Weill, poet and lyricist Langston Hughes, and playwright Elmer Rice. Rice adapted his 1929 Pulitzer prize-winning play of the same name for the musical. In the play, which premiered in New York City in January 1947, the poem's third stanza is recited, followed by duet, "Don't Forget The Lilac Bush", inspired by Whitman's verse. Weill received the first Tony Award for Best Original Score for this work African-American composer George T. Walker, Jr. (born 1922) set Whitman's poem in his composition Lilacs for voice and orchestra which was awarded the 1996 Pulitzer Prize for Music. The work, described as "passionate, and very American," with "a beautiful and evocative lyrical quality" using Whitman's words, was premiered by the Boston Symphony Orchestra on February 1, 1996. Composer George Crumb (born 1929) set the Death Carol in his 1979 work Apparition (1979), an eight-part song cycle for soprano and amplified piano.
 Passage 2:At the 1989 election, Buchanan successfully transferred to the newly recreated seat of Ashburton, with her replacement in Pilbara, Larry Graham, retaining that seat for Labor. The re-elected Dowding government persisted only until February 1990, when it was replaced by the Lawrence government following Dowding's forced resignation. New premier Carmen Lawrence elevated Buchanan to the ministry as Minister for Works and Services and Minister for Regional Development. She was also made assistant minister to Lawrence in her capacity as Minister for Aboriginal Affairs. However, the regional development portfolio was abolished in December 1990, and Buchanan lost her remaining portfolios in February 1991, as part of a ministerial reshuffle prompted by an internal spill motion. Jeff Carr and Gavan Troy were also removed as ministers, with Carr consequently resigning from parliament. Buchanan herself resigned to sit as an independent on 1 February 1991, before the new ministry was sworn in four days later. She consequently became the first woman in the Parliament of Western Australia to sit as an independent. Buchanan resigned due to ill health just over a year later, in March 1992, and died at the end of that month, aged 55. She had married George Maitland Buchanan in April 1957, with whom she had two daughters. Her resignation prompted a by-election in Ashburton, which was won by the Labor candidate Fred Riebeling.
