[Q]: Question: What was the population of Hertford in 1835? Passage:In 1835, Cowper was elected Liberal Member of Parliament for Hertford, a seat he held for the next thirty-three years, and became private secretary to his uncle Prime Minister Lord Melbourne. He was appointed a Groom in Waiting in 1837, and in 1841 served for three months as a Lord of the Treasury under Melbourne, only resuming office five years later as a Lord of the Admiralty when the Whigs returned to power under Lord John Russell. He again held this post under Lord Aberdeen from 1852 to 1855, and in the latter year was made Under-Secretary of State for the Home Department by his stepfather Lord Palmerston when he became Prime Minister. In August that same year he was appointed President of the Board of Health, and sworn of the Privy Council. Four years later he became Vice-President of the Board of Trade and Paymaster General, only serving for a year before Palmerston appointed him First Commissioner of Works.

[Q]: 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.
