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: What was the minimum sentence for possession of marijuana in Hong Kong in 1976? Passage:Mayer was born in El Paso, Texas, to Jesse and Margott Mayer. After his father died two years later, his penniless mother moved him and his brother Aubrey to New Orleans; she then entered nursing school and placed the children in an orphanage. As a teenager, Mayer attended a trade school where he trained as a tool and die maker. He left New Orleans and spent much of the 1930s travelling from job to job from Nome, Alaska, to the Caribbean, working in a rubber plant and in gold mines among other jobs. He was drafted into the United States Navy in 1944 while living in Los Angeles and spent two years stationed at the San Diego Naval Station. He was discharged as a fireman first class and returned to a life of drifting, working in Miami as a machinist in the mid-1950s, as a hotel maintenance man in Puerto Rico, the Virgin Islands and Jamaica during the 1960s, and as a helicopter mechanic in South Vietnam from 1969-1970. In 1971, he was seriously injured while working on an oil rig in Brunei and recuperated in Singapore before traveling across South Asia. In 1976, he was arrested in Hong Kong for possession of of marijuana in a botched attempt to make a sale. Mayer researched the law in jail and after fifteen months managed to have his conviction reversed on a technicality. He was deported back to the U.S. and returned to working in hotels.

Example Input: Question: What is the capital city of the country where Orson K. Miller claims to have found the Amanita abrupta? Passage:The fruit bodies of A.abrupta grow on the ground, typically solitary, in mixed conifer and deciduous forests, usually during autumn. The frequency with which fruit bodies appear depends on several factors, such as season, location, temperature, and rainfall. The mushroom has been described as common in the Southeastern United States; in Texas, it has been called both infrequent, and common in the Big Thicket National Preserve. Like most other Amanita species, A.abrupta is thought to form mycorrhizal relationships with trees. This is a mutually beneficial relationship where the hyphae of the fungus grow around the roots of trees, enabling the fungus to receive moisture, protection and nutritive byproducts of the tree, and affording the tree greater access to soil nutrients. Amanita abrupta is widely distributed throughout eastern North America, where it has been found as far north as Quebec, Canada, and as far south as Mexico. Orson K. Miller claims to have found it in the Dominican Republic where it appeared to be growing in a mycorrizhal association with pine trees. Kuo also mentions a mycorrhizal relationship with both hardwoods and conifers, while Tulloss lists additional preferred tree hosts such as beech, birch, fir, tsuga, oak, and poplar. However, A.abrupta has been shown experimentally to not form mycorrhizae with Virginia Pine.

Example Input: Question: Which country won the most gold medals at the Olympics during which the Munich massacre took place? Passage:On 15 August 2018, a British political controversy was initiated when the Daily Mail claimed that, prior to becoming Labour Party Leader, Jeremy Corbyn had been present at a 2014 wreath-laying at a cemetery which contained the graves of many Palestinian activists including Salah Khalaf and Atef Bseiso, both of whom were members of the Black September Organization and were behind the Munich massacre of Israeli athletes at the 1972 Summer Olympics. The wreath-laying took place during a commemorative ceremony for victims of the 1985 Israeli air strikes on the PLO headquarters in Tunis, Tunisia, which had been widely condemned at the time, including by the U.S. Government. Corbyn and the Conservative peer Baron Sheikh had been in Tunisia to attend the International Conference on Monitoring the Palestinian Political and Legal Situation in the Light of Israeli Aggression. The controversy was considered to be part of a wider series of issues relating to claims of antisemitism in the Labour party and Corbyn's personal position on the Middle East, which have escalated since Corbyn became a front-runner for Labour Party leader in August 2015.
