In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Example Input: Question: In which city is the headquarter of the automaker that employed Bagot located? Passage:After the war he spent another eight years organising tourist services between Iraq, Persia (now Iran) and Syria for the Mesopotamian Trading Agency of Ashar, Basrah. His wife may have joined him in 1924. He returned to South Australia in 1926 with the intention of setting up a regular service between Adelaide and Darwin via Oodnadatta and Alice Springs. He conducted a demonstration run with eight men and four women in three Studebaker cars and a Thornycroft truck, leaving Adelaide on 18 May and arrived in Darwin on 3 June; left there on 7 June and returned to Adelaide on 25 June, travelling via Camooweal, Queensland and Marree, South Australia, publicised by Duncan and Fraser (agents for both Thornycroft and Studebaker) and as they were equipped with a short-wave transceiver, gave nightly reports on radio 5CL. Despite a second successful round trip that year, Bagot abandoned his idea of regular service when the Commonwealth Government turned down his application for a subsidy. He found employment with General Motors and in 1930 "Captain Bagot" as he was called by admirers (or "'Alphabetical Bagot' as he was known to the many who disliked him), founded the Citizens' League of South Australia, which opposed Unionism, Communism and the White Australia Policy as benefiting the working classes, yet also opposing Fascism. This was the time of the Great Depression and he also supported the Young People's Employment Council and the Rev. Samuel Forsyth's (1881–1960) Forsyth Industrial Colony "Kuitpo Colony" near Kuitpo Forest, which was training boys as farm workers. The Citizen's League attempted political influence by promising support to political candidates, and was a factor in the election of the Independent candidate George Connor to the Assembly seat of Alexandra in 1934.

Example Input: Question: How many people did Arnstadt command as a company commander of the 6th border company in Dermbach? Passage:In June 1949, Arnstadt registered for service with the Volkspolizei, the police force of the Soviet Occupation Zone, becoming an Anwärter der VP (police cadet) with the Kasernierte Volkspolizei in Gotha. In March 1950, Arnstadt was appointed to the German Border Police (Deutsche Grenzpolizei) in Dermbach, patrolling the Inner German border with West Germany. In 1952, Arnstadt failed his first attempt to become an officer at the police school in Sondershausen. In 1953, his marriage ended in divorce, with his two children Veronika and Uwe staying with the mother, and remarried shortly after. In 1954, Arnstadt passed his officer training at Sondershausen and was appointed the rank of Unterleutnant, and the following year was promoted to lieutenant. Arnstadt functioned as a recruiter for the German Border Police until 1957 when he was appointed as a company commander of the 6th border company in Dermbach. Arnstadt was responsible for a section of the border at Wiesenfeld, a region of Bezirk Suhl in the Rhön Mountains at the westernmost point of the Warsaw Pact. Arnstadt's section contained the highly-strategic Fulda Gap, which aroused the special interest of NATO, and a short distance from the US Army's Observation Post Alpha. Arnstadt moved with his wife to Wiesenfeld and in April 1957 became an unofficial collaborator (Geheimer Informator) of the Ministry for State Security (Stasi) until this relationship was ended fourteen months later.

Example Input: Question: Is the place composed of one large island and several smaller island chains an independent country? Passage:A distinction is often made between the island of New Guinea and what is known as Island Melanesia, which consists of "the chain of archipelagos, islands, atolls, and reefs forming the outer bounds of the sheltered oval-shaped coral sea". This includes the Louisiade archipelago (part of Papua New Guinea), the Bismarck Archipelago (part of Papua New Guinea and Solomon Islands), and the Santa Cruz Islands (part of the country called Solomon Islands). The country of Vanuatu is composed of the New Hebrides island chain (and in the past 'New Hebrides' has also been the name of the political unit located on the islands). New Caledonia is composed of one large island and several smaller chains, including the Loyalty Islands. The nation of Fiji is composed of two main islands, Viti Levu and Vanua Levu, and smaller islands, including the Lau Islands.
