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.
One example is below.
Q: 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 were the main groups involved in the event that resulted in the sacking of Constantinople in 1204? Passage 1:On 28 June 1926, the Ludington Daily News reported that Bahia would pay a visit to Philadelphia, accepting an invitation from the United States government to participate in the sesquicentennial celebrations. In mid-1930, Bahia and Rio Grande do Sul—under the command of Heráclito Belford Gomes—escorted Brazil's President-elect Júlio Prestes to the United States. Traveling on board the Brazilian-Lloyd ocean liner , Prestes was returning American then-President-elect Herbert Hoover's visit to Brazil in December 1928. The cruisers and met the three ships about off Sandy Hook and honored Prestes with a 21-gun salute. After spending five hours in the Ambrose Channel due to fog, Prestes traveled on a launch to a pier, during which Bahia rendered one 21-gun salute and Fort Jay offered two. After arriving ashore, he traveled to City Hall before speeding down to Washington, D.C. He stayed in the United States for eight days before departing for France on the White Star Line's . Bahia and Rio Grande do Sul were berthed at the Brooklyn Navy Yard for the visit.
 Passage 2: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.
 Passage 3:Papal calls for renewed holy war at the end of the twelfth century inspired not only the disastrous Fourth Crusade that sacked Constantinople in 1204, but also a series of simultaneous "Northern Crusades" that are less fully covered in English-language popular history, but which were more successful in the long run. Before the crusades, the region of Livonia was a mixed outpost, a pagan society where merchants from the Hanseatic League encountered merchants of Novgorod, and where Germanic, Scandinavian, and Russian trade, culture, and cults all mingled. The specific ethnic groups that intermingled and traded with the Germans, Danish, Swedish, and Russians here included the Wends, who were merchants from Lübeck, the Estonians, the Karelians, the Kuronians, the Lettgallians, the Semgallians (sometimes known as the Letts), the Livonians and the Lithuanians. The Western merchants would trade silver, textiles, and other luxury goods for furs, beeswax, honey, leather, dried fish, and amber. Livonia had been an especially promising location in terms of resources, and Arnold of Lübeck, in his Chronicle of the Slavs wrote that the land was "abundant in many riches" and was "fertile in fields, plentiful in pastures, irrigated by rivers", and "also sufficiently rich in fish and forested with trees".
