Information: - Joseph Philippe Pierre Yves Elliott Trudeau (; October 18, 1919 September 28, 2000), better known as Pierre Trudeau or Pierre Elliott Trudeau, was a Canadian politician who served as the 15th Prime Minister of Canada from 19681979 and 19801984. He is the 3rd longest-serving Prime Minister in Canadian history (behind William Lyon Mackenzie King and John A. Macdonald), having served for 15 years, 164 days. - Sir John Alexander Macdonald (11 January 1815 6 June 1891) was the first Prime Minister of Canada (18671873, 18781891). The dominant figure of Canadian Confederation, he had a political career which spanned almost half a century. He drank heavily, and in 1873 was voted out during the Pacific Scandal, in which his party took bribes from businessmen seeking the contract to build the Pacific Railway. Macdonald's greatest achievements were building and guiding a successful national government for the new Dominion, using patronage to forge a strong Conservative Party, promoting the protective tariff of the National Policy, and building the transcontinental Canadian Pacific Railway. Economic growth was slow during his years in office, as Canada verged on stagnation; many residents migrated to the fast-growing United States. He fought to block provincial efforts to take power back from Ottawa. His most controversial move was to approve the execution of Metis leader Louis Riel for treason in 1885; it alienated many Francophones. - 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. - The Canadian federal election of 1968 was held on June 25 , 1968 , to elect members of the Canadian House of Commons of the 28th Parliament of Canada . The Liberal Party won a majority government under its new leader , Prime Minister Pierre Trudeau . This was the last federal election in which some provinces ( specifically Manitoba , Nova Scotia , Quebec and Saskatchewan ) had fewer seats they had been allocated in the previous election due to a redistribution . The 1966 census , for example , revealed that Alberta had a population about 50 % greater than Saskatchewan 's even though both provinces had the same number of seats at the time ( 17 ) . Saskatchewan was the only province to lose multiple seats in the redistribution ( 4 ) . It was also the only election in Canadian history where fewer total seats were contested compared to the previous vote ( 264 instead of 265 ) . Changes to the Constitution enacted since that time have rendered the prospect of similar reductions far less likely . After reading the paragraphs above, choose the best answer for the entity that related to 'canadian federal election' with the relationship of 'office contested'. Choices: - prime minister - prime minister of canada
prime minister of canada

Question: Information: - A definition is a statement of the meaning of a term (a word, phrase, or other set of symbols). Definitions can be classified into two large categories, intensional definitions (which try to give the essence of a term) and extensional definitions (which proceed by listing the objects that a term describes). Another important category of definitions is the class of ostensive definitions, which convey the meaning of a term by pointing out examples. A term may have many different senses and multiple meanings, and thus require multiple definitions. - In mathematics , the codomain or target set of a function is the set Y into which all of the output of the function is constrained to fall . It is the set Y in the notation f : X Y. The codomain is also sometimes referred to as the range but that term is ambiguous as it may also refer to the image . The codomain is part of a function f if it is defined as described in 1954 by Nicolas Bourbaki , namely a triple ( X , Y , F ) , with F a functional subset of the Cartesian product X Y and X is the set of first components of the pairs in F ( the domain ) . The set F is called the graph of the function . The set of all elements of the form f ( x ) , where x ranges over the elements of the domain X , is called the image of f. In general , the image of a function is a subset of its codomain . Thus , it may not coincide with its codomain . Namely , a function that is not surjective has elements y in its codomain for which the equation f ( x ) = y does not have a solution . An alternative definition of function by Bourbaki ( Bourbaki , op. cit. , p. 77 ) , namely as just a functional graph , does not include a codomain and is also widely used . For example in set theory it is desirable to permit the domain of a function to be a proper class X , in which case there is formally no such thing as a triple ( X , Y , F ) . With such a definition functions do not have a codomain , although some authors still use it informally after introducing a function in the form f : X Y. - Space is the boundless three-dimensional extent in which objects and events have relative position and direction. Physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. - Quantity is a property that can exist as a magnitude or multitude. Quantities can be compared in terms of "more", "less", or "equal", or by assigning a numerical value in terms of a unit of measurement. Quantity is among the basic classes of things along with quality, substance, change, and relation. Some quantities are such by their inner nature (as number), while others are functioning as states (properties, dimensions, attributes) of things such as heavy and light, long and short, broad and narrow, small and great, or much and little. A small quantity is sometimes referred to as a quantulum. - Mathematics (from Greek "mathma", knowledge, study, learning) is the study of topics such as quantity (numbers), structure, space, and change. There is a range of views among mathematicians and philosophers as to the exact scope and definition of mathematics. After reading the paragraphs above, choose the best answer for the entity that related to 'codomain' with the relationship of 'instance of'. Choices: - class - concept - definition - four - framework - mathematics - may - measurement - part - phrase - quantity - range - relation - relationship - set - space - statement - study - three - two - understanding - value
