Question: Information:  - Ian Douglas Smith, GCLM, ID (8 April 1919  20 November 2007) was a politician, farmer and fighter pilot who served as Prime Minister of Rhodesia (or Southern Rhodesia) from 1964 to 1979. The country's first premier not born abroad, he led the predominantly white government that unilaterally declared independence from the United Kingdom in 1965, following prolonged dispute over the terms. He remained Prime Minister for almost all of the 14 years of international isolation that followed, and oversaw Rhodesia's security forces during most of the Bush War, which pitted the unrecognised administration against communist-backed black nationalist guerrilla groups. Smith, who has been described as personifying white Rhodesia, remains a highly controversial figuresupporters venerate him as a man of integrity and vision "who understood the uncomfortable truths of Africa", while critics describe an unrepentant racist whose policies and actions caused the deaths of thousands and contributed to Zimbabwe's later crises.  - Winston Joseph Field MBE (19041969) was a Rhodesian politician. Field was a former Dominion Party MP who founded the Rhodesian Front political party with Ian Douglas Smith. Field was born and brought up in Bromsgrove and educated at Bromsgrove School as a Day boy, in Worcestershire, England, and moved to Southern Rhodesia in 1921. A tobacco farmer near Marandellas (now known as Marondera), in Mashonaland East, Field was President of the powerful Rhodesian Tobacco Association from 1938 to 1940, when he left for military service during the Second World War.  - The Rhodesia general election of 30 July 1974 saw the Rhodesian Front of Ian Smith re-elected , once more winning every one of the 50 seats elected by white voters .  - The Rhodesian Front (RF) was a political party in Rhodesia (or Southern Rhodesia) when the country was under white minority rule. Led first by Winston Field, and, from 1964, by Ian Smith, the Rhodesian Front was the successor to the Dominion Party, which was the main opposition party in Southern Rhodesia during the Federation period. The RF was formed in March 1962 by whites opposed to any immediate change to black majority rule. It won power in the general election that December. In successive elections (in which 50 of the 66 parliamentary seats were reserved for A-Roll voters, who had to meet a higher standard of qualifications, increasing the proportion of white Africans who came under this roll) between 1964 and 1979, the RF was returned to office, with a large majority, with Smith as Prime Minister.  - Rhodesia, commonly known from 1970 onwards as the Republic of Rhodesia, was an unrecognised state in southern Africa from 1965 to 1979, equivalent in territorial terms to modern Zimbabwe. With its capital in Salisbury (now Harare), Rhodesia was considered a "de facto" successor state to the former British colony of Southern Rhodesia (which had achieved responsible government in 1923).  - Responsible government is a conception of a system of government that embodies the principle of parliamentary accountability, the foundation of the Westminster system of parliamentary democracy. Governments (the equivalent of the executive branch) in Westminster democracies are responsible to parliament rather than to the monarch, or, in a colonial context, to the imperial government, and in a republican context, to the president, either in full or in part. If the parliament is bicameral, then the government is responsible first to the parliament's lower house, which is more numerous, always directly elected and thus more representative than the upper house. Responsible government of parliamentary accountability manifests itself in several ways. Ministers account to Parliament for their decisions and for the performance of their departments. This requirement to make announcements and to answer questions in Parliament means that ministers have to have the privileges of the "floor" which are only granted to those who are members of either house of Parliament. Secondly, and most importantly, although ministers are officially appointed by the authority of the head of state and can theoretically be dismissed at the pleasure of the sovereign, they concurrently retain their office subject to their holding the confidence of the lower house of Parliament. When the lower house has passed a motion of no confidence in the government, the government must immediately resign or submit itself to the electorate in a new general election.    Given the information above, choose from the list below the object entity that exhibits the relation 'office contested' with the subject 'rhodesian general election'.
