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.

[EX Q]: Question: On what date did Recitation win its maiden race at Newbury Racecourse? Passage:After finishing third over five furlongs on his racecourse debut, Recitation won a maiden race over the same distance at Newbury Racecourse, beating I'll See You by half a length. The colt was then moved up sharply in class for the Group Three Coventry Stakes over six furlongs at Royal Ascot in June in which he was ridden by Greville Starkey and started at odds of 11/1. In a performance which Timeform described as "a revelation", Recitation took the lead a quarter mile from the finish and drew clear of the field to win easily by five lengths from Motavato, Bel Bolide and Another Realm. The form of the race was subsequently boosted when the third and fourth placed horses won the Gimcrack Stakes and the Richmond Stakes respectively. In the July Stakes at Newmarket Racecourse Recitation started 2/5 favourite against two opponents, but was beaten two and a half lengths by Age Quod Agis.

[EX Q]: Question: How many years were there between the end of the British Burma Campaign and the start of the Battle of Na San? Passage:The First Indochina War had raged, as guerrilla warfare, since 19 December 1946. From 1949, it evolved into conventional warfare, due largely to aid from the communists of the People's Republic of China ("PRC") to the north. Subsequently, the French strategy of occupying small, poorly defended outposts throughout Indochina, particularly along the Vietnamese-Chinese border, started failing. Thanks to the terrain, popular support for August Revolution and support for decolonization from bordering China and the U.S.S.R., the Viet Minh had succeeded in turning a "clandestine guerrilla movement into a powerful conventional army", following asymmetric warfare theory laid by Mao Tse Tung, something which previously had never been encountered by the western colonial powers. In October 1952, fighting around the Red River Delta spread into the Thai Highlands, resulting in the Battle of Nà Sản, at which the Viet Minh were defeated. The French used the lessons learned at Nà Sản – strong ground bases, versatile air support, and a model based on the British Burma Campaign – as the basis for their new strategy. The Viet Minh, however, remained unbeatable in the highland regions of Vietnam, and the French "could not offset the fundamental disadvantages of a roadbound army facing a hill and forest army in a country which had few roads but a great many hills and forests".

[EX Q]: 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.
