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:
Question: Does the entity that Roberts was elected to in 1978 have more than 100 members? Passage:Of those Phillies, 97 have had surnames beginning with the letter R. Two of those players have been inducted into the Baseball Hall of Fame: pitcher Eppa Rixey, who was a Phillie for six seasons in two different stints (1912–1917, 1919); and Robin Roberts, who won 20 games during the 1950 season as the ace pitcher of the Whiz Kids. The Hall of Fame lists the Phillies as Roberts' primary team; during his career, the right-hander won 234 games and lost 199, the latter one of his three franchise records. During his 14 seasons with the team, he pitched 3,739  innings and completed 272 games, both records; he also held the major league record for most career home runs allowed until it was broken in 2010. Roberts was also elected to the Philadelphia Baseball Wall of Fame as the Phillies' first inductee in 1978.

question:
Question: What was the capacity of the venu where Port Vale F.C. suffered a loss of 7–3 to Shrewsbury Town? Passage:The season began with two wins, but a run of one win in ten games then followed. In September, four of the five directors resigned, one of them (Len Cliff) stated that "the club is being run by outsiders". A new board was formed by November. Meanwhile, on 13 September the club suffered a loss of 7–3 at Gay Meadow to Shrewsbury Town, despite a Bobby Gough hat-trick – the match also saw a sending off, an attempted pitch invasion, and a £35 fine for Gordon Lee for remarks he made to referee Ricky Nicholson. Tommy McLaren then returned from injury to lead Vale on a four match winning streak that included a 2–0 win over fallen-giants Aston Villa in front of a Burslem crowd of 11,224 fans. Four straight defeats soon came after this sequence however, as Vale's form was patchy. In December, Ron Wilson left the club as he emigrated to South Africa due to his son's ill health. A 1–0 defeat at Villa Park on 16 January was the first of a nine match streak without a victory. At the end of the month Lee signed John Brodie from Northern Premier League side Bradford Park Avenue for £250. During this spell forward Sammy Morgan began to be jeered by fans after losing his scoring touch. He also began studying to be a teacher. Lee said that "I really feel some of our lads have been singled out by the boo boys. If only they realised that encouragement can lift players, things would be so much better". In February, Mark Singer resigned as chairman, and was replaced by Graham Bourne. By then the club were hovering above the relegation zone, but a record of just ten goals conceded in their final twelve games was enough to secure safety, with Brian Horton in good form.
