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.

The question refers to the 704th unit and task about war which is decribed by Passage 1.

New input case for you: Question: What year was the building constructed that Lewis because a chorister at when he was eight years old? Passage 1:The series follows the adventures of a group of girls known as the Winx, students (and later graduates) at the Alfea College for Fairies, who turn into fairies to fight villains. The team consists of Bloom, the red-haired leader with flame-based powers; Stella, the fairy of the Sun and Moon; Flora, the fairy of nature; Tecna, the fairy of technology; Musa, the fairy of music; and Aisha, the fairy of waves. Roxy, the fairy of animals, occasionally joins the Winx and all three of the show's production companies refer to her as the Winx Club's seventh member. The main male characters are called the Specialists, a group of students and later graduates of the Red Fountain school who are romantically involved with the Winx fairies. They include Bloom's fiance Sky; Stella's fiance Brandon; Flora's boyfriend Helia; Tecna's boyfriend Timmy; and Musa's boyfriend Riven. Unlike their female counterparts, the Specialists do not have magical powers and instead train how to fight using laser weapons. The Winx and Specialists' most frequent adversaries are a trio of witches named the Trix: Icy, Darcy, and Stormy, all of whom are former students of the Cloud Tower school.
 Passage 2:Lewis was born in Bermuda, the youngest of the three children – all boys – of Major Leonard Carey Lewis (1880–1952) and his wife, Katherine Barbara, née Sutton (1884–1965). There was a military tradition on both sides of the family, which the young Lewis did not follow: his musical talent became clear from his early years and he was sent to Salisbury Cathedral choir school, and at the age of eight he became a chorister at St George's Chapel, Windsor. At the age of 13 Lewis attended the Royal Academy of Music (RAM), London, studying composition with William Alwyn. He won a scholarship to Wellington College, from where, in 1932, he went to Peterhouse, Cambridge. There, according to The Times, he was "one of the most brilliant of his generation to have come under the influence of E.J.Dent". A scholarship enabled him to spend some months studying in Paris with Nadia Boulanger in 1934. He graduated the following year as BA and MusB.
 Passage 3:In August 1982 he joined Bruce Rioch's Torquay United on non-contract terms following his return to the UK. He was rewarded with a one-year contract, scoring nine times in 42 league games as well as the winning goal in the FA Cup tie at home to Oxford United that saw the Gulls through to the Fourth Round for only the fourth time in their history. Despite a successful season, he left at the end of it, returning to Wisbech Town debuting in the 1–0 Eastern Counties League victory at Tiptree United on 20 August 1983. He moved on to join Irish side Drogheda United, helping them defeat Athlone Town 3–1 at Tolka Park on 5 January 1984 to lift the League of Ireland Cup. Gallagher returned to Wisbech Town for the 1984–85 season before rejoining another of his former clubs, Peterborough United, in August 1985. His second spell proved his strongest in league football, as he netted 24 goals in 82 league games, earning a move to Wolverhampton Wanderers in June 1987. He found opportunities limited at Molineux due to the prolific partnership of Steve Bull and Andy Mutch, but did play at Wembley in their victory in the Sherpa Van Trophy in May 1988. He was loaned to both Wisbech Town and Kettering Town during the following season before being released in September 1989, and joining Conference side Boston United.
