Task: Question Answering
Input (English): Context: William Lyon Mackenzie King (December 17, 1874  July 22, 1950) was the dominant Canadian political leader from the 1920s through the 1940s. He served as the tenth Prime Minister of Canada from 1921 to 1926, 1926 to 1930, and 1935 to 1948. He is best known for his leadership of Canada throughout the Second World War (19391945) when he mobilized Canadian money, supplies and volunteers to support Britain while boosting the economy and maintaining home front morale. A Liberal with 21 years and 154 days in office, he was the longest-serving prime minister in Canadian history. Trained in law and social work, he was keenly interested in the human condition (as a boy, his motto was "Help those that cannot help themselves"), and played a major role in laying the foundations of the Canadian welfare state., A minority government, or minority cabinet or minority parliament, is a cabinet formed in a parliamentary system when a political party or coalition of parties does not have a majority of overall seats in the parliament. It is sworn into office, with or without the formal support of other parties, to enable a government to be formed. Under such a government, legislation can only be passed with the support of enough other members of the legislature to provide a majority, encouraging multi-partisanship. In bicameral parliaments, the term relates to the situation in chamber whose confidence is considered most crucial to the continuance in office of the government., William Lyon Mackenzie (March 12, 1795  August 28, 1861) was a Scottish-Canadian-American journalist and politician. He was the first mayor of Toronto and was a leader during the 1837 Upper Canada Rebellion., The Canadian federal election of 1925 was held on October 29 to elect members of the Canadian House of Commons of the 15th Parliament of Canada . Prime Minister William Lyon Mackenzie King 's Liberal Party formed a minority government . This precipitated the `` King - Byng Affair '' . The Liberals under Mackenzie King won fewer seats than Arthur Meighen 's Conservatives . A third party , the Progressives , which had nominated candidates for the first time in the 1921 election , held the balance of the seats . King decided to hold on to power with the help of the Progressives . The Progressives were closely aligned with the Liberals , and enabled King to form a minority government . This plan was complicated by the fact that his party won fewer seats than the Conservatives , and that King himself had lost his seat in the House of Commons . Meighen was outraged by King 's move , and demanded that King resign from the Prime Minister 's office . King asked a Liberal Member of Parliament from Prince Albert , Saskatchewan to resign so that he could run in the resulting by - election . Prince Albert was one of the safest seats in Canada for the Liberals , and King won easily . With King back in Parliament , a huge scandal rocked the King cabinet when one of his appointees was discovered to be accepting bribes . Anticipating a vote of censure by the Commons , King asked the Governor General , Baron Byng of Vimy , to call an election . The Governor General refused , and King resigned . King claimed this was interference in Canadian politics by an official appointed by a foreign power . King showed rare fire , and rallied the Progressives back into his camp . He defeated Meighen on a vote of confidence after only three days , making the Meighen government of 1926 the shortest lived government in Canadian history . This time , Byng called an election ., A parliamentary system is a system of democratic governance of a state where the executive branch derives its democratic legitimacy from the legislature (parliament) and is also held accountable to that legislature. In a parliamentary system, the head of state is normally a different person from the head of government. This is in contrast to a presidential system in a democracy, where the head of state often is also the head of government, and most importantly, the executive branch does not derive its democratic legitimacy from the legislature., Subject: canadian federal election, Relation: office_contested, Options: (A) head of state (B) mayor (C) prime minister (D) prime minister of canada
