Detailed Instructions: 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.
See one example below:
Problem: 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: What years did the legendary coach that Walsh worked for lead the Bengals? Passage 1:On May 7 against the Detroit Tigers, Mark Buehrle pitched a no-hitter through seventh inning before Plácido Polanco hit a line-drive double to left field; however the Sox shut out the Tigers 6–0. On May 11 against the Cleveland Indians in Progressive Field, Carlos Quentin hit a slump after suffering from plantar fasciitis which hampered his swing. He was forced to miss two games as a result of the injury. On May 15–18, Sox played with Toronto Blue Jays and Sox lost all four games in Toronto for two straight years and lost 10 straight games in Toronto since June 1, 2007. On May 21 against the Minnesota Twins, the Sox had a biggest loss 20–1 since May 10, 2002, when Sox lost to Anaheim Angels 19–0 in Los Angeles. On May 24 against the Pittsburgh Pirates, in the top of the ninth inning, Jack Wilson hit his first home run of season and tied the game at 3. The next batter Nyjer Morgan hit a double and then Delwyn Young singled and Morgan scored from second and Sox trailed it 4–3. In the bottom of the ninth inning, all batters that Matt Capps faced struck out swinging. The next day in Los Angeles against the Angels, the Sox scored 17 runs in one game, the most runs since the 2006 season. Also on that day, Carlos Quentin suffered his heel injury after he hit a double and he was placed on the 15-day disabled list. The last three games of that month, Sox swept the Royals in Kansas City. The White Sox finished May 13–15.
 Passage 2:Shah Nawaz Bhutto, a direct descendant of Muhammad Khan, came to prominence during the British Raj as a dewan of the princely state of Junagadh in south-western Gujarat in India. During the Partition of India in 1947, the Muslim Nawab of Junagarh wanted to accede his state to the newly created Pakistan, but he faced rebellion by the population of Junagadh, majority of whom were Hindus. The Indian government thwarted Junagadh's accession to Pakistan, and the Bhuttos fled to Sindh in modern-day Pakistan. Shah Nawaz Bhutto moved to Larkana District in Sindh, where his land-ownership made him one of the wealthiest and most influential people in Sindh. Beginning the political dynasty, Shah Nawaz's third son Zulfikar Ali Bhutto (1928-1979) founded the Pakistan People's Party (PPP) in 1967 and served as President and Prime Minister. He married an Iranian-Kurdish woman named Nusrat Bhutto. His daughter, Benazir (1953-2007), also served as Prime Minister, while Benazir's husband, Asif Ali Zardari, later served as president from 2008 to 2013. The Bhuttos continue to dominate the leadership of the PPP. Benazir's son Bilawal Bhutto Zardari became co-chairperson in 2007.
 Passage 3:Walsh first developed what would become the West Coast offense when he was offensive coordinator of the Cincinnati Bengals, working under legendary head coach Paul Brown. However, Walsh truly perfected this strategy as the head coach of the San Francisco 49ers. His teams were led by quarterback Joe Montana. Montana, who was noted for his ability to remain calm under pressure, also possessed good mobility and an accurate passing arm. Another important player in the 49ers offense was Roger Craig, a swift, speedy running back who could also catch passes out of the backfield and was a good receiver. Walsh's 49ers teams also featured several All-Pro wide receivers, including Dwight Clark, John Taylor, and Jerry Rice. The 49ers were one of the NFL's powerhouses in the 1980s and 1990s, under the guidance of head coaches Bill Walsh (1979–1988) and George Seifert (1989–1996). Walsh won three Super Bowls in the 1981, 1984 and 1988 seasons. Seifert won two Super Bowls in 1989 and 1994. Montana, Walsh and Rice are in the Pro Football Hall of Fame, and so is Montana's successor, quarterback Steve Young. Like Montana, Young was a great running quarterback and a very efficient passer.
