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: How many students were enrolled in Carleton University the year Clayoquot Sound was listed as a Biosphere Reserve? Passage 1:Scott Fraser was born and raised in Ottawa, Ontario, and attended Carleton University. In 1979 he moved to Alberta and worked on the oil rigs throughout the province and in the Arctic. He eventually moved to Vancouver, British Columbia, then, in 1992, to Tofino. With his wife and young daughter, he opened a bed and breakfast business. Only four years later, Fraser became the mayor of Tofino. He was mayor from November 1996 to November 1999, a time when tourism was over-taking logging and fishing as the town's dominant industry. Fraser was supportive of the application to the United Nations to designate Clayoquot Sound as a biosphere site; Clayoquot Sound was listed as a Biosphere Reserve in 2000. Fraser was the subject of a complaint filed at the British Columbia Ombudsman by one of his councillors, Ken Gibson. The mayor and council issued a resolution stating that Gibson had violated conflict-of-interest laws, using his position on council to influence zoning restrictions on his property. Gibson challenged the resolution at the BC Supreme Court which ruled in Gibson's favour, ordering that Gibson be re-instated as a councillor. The mayor and council voted in favour of appealing the decision but the Court of Appeal upheld the decision. Fraser was defeated in his attempt at re-election as mayor. In 2000, the former mayor was appointed to Tourism BC's board of directors and to the Clayoquot Sound Central Region Board which considered pre-treaty land use-related decisions. He accepted job as an assistant manager of the Tofino Harbour Authority and served as the chairman of the Working Sound Shellfish Committee.
 Passage 2:Richard James Wood (25 August 1920 – 9 October 2008) was a British Anglican bishop and anti-apartheid campaigner. He was ordained in the Church of England and served his curacy in the Diocese of Salisbury. He then moved to South Africa and served in a number of parish posts before becoming the Suffragan Bishop of Damaraland in 1973. He was expelled from South Africa in 1975 for speaking out against the apartheid government. He returned to England permanently in 1977, and became Vicar of St Mary's Church, Hull and chaplain to the University of Hull; during this time, he was also an Assistant Bishop in the Diocese of York. His final post before retirement, from 1979 to 1983, was as a member of staff of St Mark's Theological College, Dar es Salaam.
 Passage 3:She graduated from the University of Melbourne, then left to work for the Sydney Daily Mirror. In 1967 she quit the paper and travelled to Vietnam to cover the escalating war. Webb was soon hired by UPI and earned a reputation as a hard-drinking, chain-smoking war correspondent: She was the first wire correspondent to reach the U.S. Embassy in Saigon during the Tet offensive. With the death of Phnom Penh bureau chief Frank Frosch in 1970, Webb was selected to fill his position—she later claimed it was because she spoke French. In 1971 she made news herself when she was captured by North Vietnamese troops operating in Cambodia. Premature official reports claimed that a body discovered was Webb's, and The New York Times published an obituary. She emerged from captivity 23 days after she was captured, after having endured forced marches, interrogations, and malaria. She described her experiences in a book called On the Other Side, and in War Torn, a collection of reminiscences by women correspondents in the Vietnam War.
