Question: How many years did Justin's father's party have power before being defeated in the 1979 election? Passage:Trudeau lived at 24 Sussex Drive, Ottawa, the official residence of Canada's prime minister, from his birth until his father's government was defeated in the federal election on May 22, 1979. The Trudeaus were expected to move into the residence of the Leader of the Official Opposition, Stornoway, at 541 Acacia Avenue in Rockcliffe Park, but because of flooding in the basement, prime minister Joe Clark offered them Harrington Lake, the prime minister's official country retreat in Gatineau Park, with the expectation they would move into Stornoway at the start of July. However, the repairs were not complete so Pierre Trudeau took a prolonged vacation with his sons to the Nova Scotia summer home of his friend, MP Don Johnston, and later sent his sons to stay with their maternal grandparents in North Vancouver for the rest of the summer while he slept at his friend's Ottawa apartment. Justin and his brothers returned to Ottawa for the start of the school year, but lived only on the top floor of Stornoway while repairs continued on the bottom floor. His mother purchased and moved into a new home nearby at 95 Queen Victoria Avenue in Ottawa's New Edinburgh in September 1979. The Trudeaus returned to the prime minister's official residence in February 1980 after the election that returned his father to the Prime Minister's Office.

Question: How long was Patasse leader of the MLPC? Passage:On 3 March 1982, opposition politician and leader of the MLPC party, Ange-Félix Patassé, returned from exile to the Central African Republic and staged an unsuccessful coup against General André Kolingba (who himself took power in the 1981 coup d'état) with the help of a few military officers, such as General François Bozizé, who accused Kolingba of treason and proclaimed the change of power on Radio Bangui. Four days later, having failed to gain the support of the Central African Armed Forces, Patassé went in disguise to the French Embassy in the Central African Republic to seek refuge. After heated negotiations between the Kolingba government and France, Patassé was allowed to leave for exile in Togo. Bozizé fled to the north of the country with 100 soldiers, before obtaining refuge in France.

Question: In which city did Slobe attend art school? Passage:Slobe was born in Pittsburgh to a well-to-do Jewish family, and grew up in Chicago, enrolling in the School of the Art Institute of Chicago at 16; by 19 she was exhibiting paintings and winning prizes. She began exhibiting sculpture as well by the late 1930s, and came eventually to be known more as a sculptor than as a painter. In 1939 and 1940 she worked for the Works Progress Administration, creating art and teaching in a number of states, including Oregon. She became acquainted at this point with George Perle, whom she married in 1940; in 1942 the couple joined the Socialist Workers Party, and she took the pseudonym "Laura Gray". She was soon tasked with assisting in the organization of automotive workers, and it was at this time that she began her cartooning career. Encouraged to submit drawings to The Militant, her first appeared in the paper on March 4, 1944; she went on to become the paper's staff artist, submitting at least one cartoon almost weekly for the rest of her life. These drawings, which have been compared to the work of Boardman Robinson, Hugo Gellert, and Robert Minor, would be published in Trotskyist publications around the world. Some of her cartoons on the subject of civil rights would also be published in the African-American press.
