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: 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.

Now, solve this: Question: How many died at Austerlitz when Darmagnac fought there? Passage 1:Norman Joseph McAtee (June 28, 1921 – August 25, 2010) was a professional ice hockey player who played 13 games in the National Hockey League with the Boston Bruins. Born in Stratford, Ontario, he and his brother Jud played together in junior ice hockey with the Oshawa Generals during the years when the Generals dominated the Ontario Hockey League, winning championships with them in 1938–39. 1939–40 and 1940–41. At the end of the 1941 season, Norm joined his brother by signing as a free agent with the Detroit Red Wings in the NHL. However, beginning in 1942 and lasting throughout World War II, Norm became a flying officer in the Royal Canadian Air Force. After his discharge in 1945, he teamed with his brother in the Red Wings farm system before the two of them were traded to the Chicago Blackhawks for Doug McCaig in December 1945. Just over a month later, Chicago traded him to Boston for Bill Jennings, and Norm joined the Bruins for 13 games, recording one assist. After that, he finished his career in the minor leagues, ending as player-coach with the Troy Bruins in Troy, Ohio from 1951 to 1954.
 Passage 2:Channel 11, as KFJZ-TV, first signed on the air at 2:30 p.m. on September 11, 1955, after a launch ceremony culminating in Fort Worth oilman Sid Richardson flipping the ceremonial switch to activate the transmitter. It was the first independent station to sign on in Texas, the fourth television station to sign on in the Dallas–Fort Worth Metroplex (after NBC affiliate WBAP-TV (channel 5, now KXAS-TV), which signed on the air on September 29, 1948; ABC affiliate KBTV (channel 8, now WFAA), which debuted on September 17, 1949; and CBS affiliate KRLD-TV (channel 4, now Fox owned-and-operated station KDFW), which debuted on December 3, 1949), and the first to debut in the market since the FCC's 1952 lifting of a four-year freeze on new applications for television station licenses. Originally, Channel 11 maintained a 9½-hour per day programming schedule, starting with its sign-on at 2:30 p.m. and concluding at its midnight sign-off. The station originally operated from facilities at 4801 West Freeway (in the present-day location of Interstate 30) in Fort Worth.
 Passage 3:Jean Barthélemy Claude Toussaint Darmagnac (1 November 1766 – 12 December 1855) became a French division commander during the Napoleonic Wars. In 1791 he joined a volunteer battalion and soon became a captain. He fought with the 32nd Line Infantry Demi-Brigade against the Austrians in Italy. He participated in the French campaign in Egypt and Syria, being promoted to lead the regiment after distinguishing himself at the Battle of the Pyramids. He was badly wounded at Acre and promoted to general of brigade in 1801. Darmagnac fought at Austerlitz in 1805 and led the Paris guard in 1806–1807. Going to Spain, he was wounded at Medina de Rioseco and became a general of division in 1808. After serving as provincial governor, he assumed command of a combat division at Vitoria, the Pyrenees, the Bidassoa, the Nivelle, the Nive, Orthez, and Toulouse. After holding interior commands under the Bourbon Restoration he retired in 1831. His surname is one of the names inscribed under the Arc de Triomphe, on Column 36.
