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.
