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 input: 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.

Q: Question: What year was the high school founded that Thomson attended? Passage 1:The street has been a main thoroughfare since at least medieval times, and in the Middle Ages was known as "the road to Reading" or "the way from Colnbrook". Around 1611 or 1612, a Robert Baker acquired land in the area, and prospered by making and selling piccadills. Shortly after purchasing the land, he enclosed it and erected several dwellings, including his home, Pikadilly Hall. What is now Piccadilly was named Portugal Street in 1663 after Catherine of Braganza, wife of Charles II, and grew in importance after the road from Charing Cross to Hyde Park Corner was closed to allow the creation of Green Park in 1668. Some of the most notable stately homes in London were built on the northern side of the street during this period, including Clarendon House and Burlington House in 1664. Berkeley House, constructed around the same time as Clarendon House, was destroyed by a fire in 1733 and rebuilt as Devonshire House in 1737 by William Cavendish, 3rd Duke of Devonshire. It was later used as the main headquarters for the Whig party. Burlington House has since been home to several noted societies, including the Royal Academy of Arts, the Geological Society of London, the Linnean Society, and the Royal Astronomical Society. Several members of the Rothschild family had mansions at the western end of the street. St James's Church was consecrated in 1684 and the surrounding area became St James Parish.
 Passage 2:Born in 1954, Brammer was educated at the Alpha Boys School. After initially working under the name Prince Glen, he began working under the stage name Trinity, taken from the spaghetti western character. After working as a deejay on several Kingston sound systems, he made his debut recording in March 1976 with "Set Up Yourself" for producer Joseph Hoo Kim. "Words of The Prophet" followed for Yabby You, who also produced his debut album, Shanty Town Determination. Late in 1976, he joined up with Dillinger for the "Crank Face" single, and the Clash album, produced by UK-based producer Clement Bushay. 1977 saw the deejay in great demand, recording more than 20 singles for a variety of producers, including Winston Riley, Tommy Cowan, Joe Gibbs, and Yabby You, his biggest hit coming with "Three Piece Suit" for Gibbs, featuring Trinity toasting over a new version of Alton Ellis's "I'm Still In Love With You" rhythm, with a lyric that anticipated the move from 'cultural' lyrics to more material/carnal concerns of the dancehall era. This prompted an answer record from Althea & Donna using the same rhythm, in the form of the UK-chart topping "Uptown Top Ranking". Trinity recorded "Slim Thing" in response, but failed to match Althea & Donna's success. 1977 also saw the release of the Uptown Girl album, produced by Bunny Lee, and strong albums in 1978 in the form of Three Piece Chicken and Chips (with Ranking Trevor) and Showcase. In 1978, Trinity also performed at the One Love Peace Concert in Kingston. In the later 1970s, Trinity began producing both himself and other artists, starting his own Flag Man label. In 1979, he recorded the duet "Funny Feeling" with Dennis Brown, and joined up with Barrington Levy for "Lose Respect" and "I Need a Girl" in 1979 and 1980 respectively. Subsequent albums met with diminishing commercial success, and Trinity switched from deejaying to singing, releasing the albums Telephone Line and Hold Your Corner in 1987 under the name Junior Brammer.
 Passage 3:Thomson was born in Dundee, and attended Brechin High School. He made his debut for Scotland in June 1992, in a first-class game against Ireland. Later in 1992, and also in 1994, Thomson trialled with English counties, playing Second XI Championship games for Leicestershire and Durham, respectively. At the 1997 ICC Trophy in Malaysia, he played in five of Scotland's nine matches, taking six wickets. His best figures, 3/37 from eight overs, came against Papua New Guinea. Thomson was a regular for Scotland throughout the late 1990s and into the early 2000s, although he missed out on both the team's appearance at the 1999 World Cup and the 2001 ICC Trophy. His final matches for the national team came in the 2003 National Cricket League, against Derbyshire and Lancashire.
