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.

Ex Output:

Question: What is the height of the peak of the mountain where the Aspen Mountain ski resort was established? Passage:The Company was founded in 1946 by Friedl Pfeifer, an Austrian ski instructor and racing champion, Walter Paepcke, a successful Chicago industrialist, Judge William E. Doyle, James J. Johnston, and H. F. Klock. Paepcke also founded cultural institutions in the city, such as the Aspen Institute and the Aspen Music Festival. The Aspen Skiing Company established the Aspen Mountain ski resort on Aspen Mountain above the town of Aspen, Colorado. The first chair lift, Lift-1, opened on December 14, 1946, and was the world's longest chairlift at the time. In 1950, the company hosted the FIS World Alpine Championships, the first international skiing competition in the United States. In the following decades, the company opened Buttermilk in 1958 and the Snowmass (originally the Snowmass-at-Aspen Ski Area) in 1967. In 1993 the company assumed ownership and operation of Aspen Highlands, which was founded in 1958 by Colorado Ski Hall of Famer: Whip Jones. Previously, Jones successfully sued Aspen Skiing before the Supreme Court for antitrust violations in Aspen Skiing Co. v. Aspen Highlands Skiing Corp.

Question: Did the B-47 Stratojet exist during World War II? Passage:RAF Mildenhall opened on 16 October 1934. King George V reviewed 350 aircraft there in 1935 on the occasion of his Silver Jubilee. This historical event is commemorated by a memorial tablet located in front of the Building 562, the current 100 ARW headquarters. During World War II, Mildenhall became a bomber station, flying Vickers Wellingtons, Short Stirlings and Avro Lancasters. It was also the headquarters of 3 Group Bomber Command. From 1950, Mildenhall became home to bombers and later tanker aircraft of the United States Air Force. Throughout the 1950s, Strategic Air Command bomber units were deployed on a regular rotational basis from the United States to the United Kingdom. The B-47 Stratojet was a familiar sight in the skies over RAF Mildenhall and RAF Upper Heyford at this time, as entire wings deployed on 90-day rotations. From 1976 to 1990, the SR-71 Blackbird was flown out of Mildenhall by Detachment 4 of the 9th Strategic Reconnaissance Wing of the USAF. RAF Mildenhall was, until 2003, the home of the largest military-sponsored air show in Europe, when it was cancelled because of increasing operational requirements.

Ex Output:
