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: Of the Grand Prix that di Resta actually drove in, which had been in existence the longest? Passage 1:The son of Gordie Ion, Ion graduated from Burnaby North Secondary School. In 1981, the Portland Timbers selected him in the first round of the North American Soccer League draft. However, he lost the entire 1981 season with a knee injury. He came back in 1982 and played nine games, but the team folded at the end of the season. He then signed with the Montreal Manic, but that team collapsed at the end of the 1983 season. On November 10, 1983, the Fort Lauderdale Strikers purchased his contract from the Manic. The Strikers sent Ion to the Tulsa Roughnecks during the 1984 pre-season. When the NASL collapsed at the end of the season, Ion moved to the Los Angeles Lazers of the Major Indoor Soccer League. He remained with the Lazers until March 26, 1987 when the team traded him to the Minnesota Strikers in exchange for Thompson Usiyan. He finished the season with the Strikers. On October 2, 1987, the Strikers traded him to the San Diego Sockers in exchange for draft picks and cash. On November 6, 1987, the Sockers waived Ion during the pre-season as part of a salary reduction move. The Chicago Sting quickly signed him and he spent the 1987–1988 season in Chicago. The Sting, facing financial collapse, released Ion and ten other players on June 2, 1988. Ion then moved to the Kansas City Comets for two seasons. In 1990, he moved to the Tacoma Stars for two seasons.
 Passage 2:In December 2009, with Fisichella having moved to Ferrari and Liuzzi being promoted to the race team, di Resta took part in a test with the team at the Jerez circuit alongside J. R. Hildebrand. At the Autosport International show in January 2010, he was said to be close to a deal as the team's test and reserve driver for the 2010 season. The deal was announced on 2 February. Di Resta made his Formula One race meeting début at the 2010 Australian Grand Prix, where he took part in the first free practice session in place of Sutil and placed 11th. He drove in the first practice sessions of all the following races until Monaco Grand Prix, where he did not take part. He resumed driving for the team at the European Grand Prix and the following British Grand Prix. After sitting out the German Grand Prix he returned for the Hungarian Grand Prix. Di Resta subsequently sat out the Belgian Grand Prix as Tonio Liuzzi and Adrian Sutil needed as much track-time as possible to get the feeling of the new parts. He participated in practice for the Italian Grand Prix, but did not participate in the Singapore or Japanese Grands Prix. The team elected that di Resta should miss the Korean Grand Prix to allow Liuzzi and Sutil to get used to the new track for the race.
 Passage 3:Seeing her greatest level of success in the 1980s, Branigan's other singles included the Top 10 hit "Solitaire" (1983), the U.S. AC chart number one "How Am I Supposed to Live Without You" (1983), the Australian No. 2 hit "Ti amo" (1984), and "The Power of Love" (1987). Her most successful album was 1984's platinum-selling Self Control. She also contributed songs to motion picture and television soundtracks, including the Grammy and Academy Award-winning Flashdance soundtrack (1983), and the Ghostbusters soundtrack (1984). In 1985, she won the Tokyo Music Festival with the song "The Lucky One". Her chart success began to wane as the decade closed and after her last two albums Laura Branigan (1990) and Over My Heart (1993) garnered little attention, she generally retired from public life for the rest of the 1990s. She began returning to performing in the early 2000s, most notably appearing as Janis Joplin in the off-Broadway musical Love, Janis. As she was recording new music and preparing a comeback to the music industry, she died at her home in 2004 from a previously undiagnosed cerebral aneurysm.
