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: How long after the construction of the cathedral where Rachel Treweek became the 41st Bishop was she installed there? Passage:On 26 March 2015, it was announced that Treweek was to become the next Bishop of Gloucester, the diocesan bishop of the Diocese of Gloucester. Though there had been two women appointed bishops previously in the Church of England, she was the first woman to be appointed a diocesan bishop, rather than as a suffragan bishop. She was the first woman to become a bishop in the Province of Canterbury, jointly with Sarah Mullally, Bishop of Crediton. On 15 June 2015, her election was confirmed during a sitting of the Arches Court of Canterbury at St Mary-le-Bow, City of London. At this point, she legally became the Bishop of Gloucester. On 22 July 2015, she was consecrated a bishop by Justin Welby, the Archbishop of Canterbury, during a ceremony at Canterbury Cathedral. She and Sarah Mullally (later Bishop of London) were the first women to be ordained as bishops at Canterbury Cathedral. On 19 September, she was installed at Gloucester Cathedral as the 41st Bishop of Gloucester.

Example Input: Question: How many President's children have lived in the White House? Passage:Within weeks, many Americans could recite favorite lines from the record, including "the rubber schwan [swan] is mine", and "move ahead...with great vigah [vigor]", the latter lampooning the President's own words. The album poked fun at Kennedy's PT-109 history; the rocking chairs he used for his painful back; the Kennedy clan's well-known athleticism, football games and family togetherness; children in the White House; and Jackie Kennedy's soft-spoken nature and her redecoration of the White House; and many other bits of knowledge that the public was eager to consume. Kennedy himself was said to have given copies of the albums as Christmas gifts, and once greeted a Democratic National Committee group by saying, "Vaughn Meader was busy tonight, so I came myself." According to UPI reporter Merriman Smith, during a Cabinet meeting Kennedy played the entire record for everyone. At one press conference, Kennedy was asked if the album had produced "annoyment (sic) or enjoyment." He jokingly responded, "I listened to Mr. Meader's record and, frankly, I thought it sounded more like Teddy than it did me. So, now he's annoyed."

Example Input: Question: Was Armstrong born in the most populous city in its state? Passage:She was born in New Orleans, Louisiana, and was graduated from Vassar College in 1949. In 1950, she married Tobin Armstrong and moved to Kenedy County, Texas. From 1966 to 1968, she was the vice chairman of the Texas Republican Party. From 1971 to 1973 she was Co-chairman of the Republican National Committee, and she was the keynote speaker at the 1972 Republican National Convention. (She was the first woman from either major party to keynote at a national convention). Nixon named her as Counselor to the President on 19 December 1972, which she held from January 19, 1973 to November 1974 under President Ford. During her tenure as Counselor, Armstrong founded the first Office of Women's Programs in the White House, predecessor to the current White House Council on Women and Girls. Fluent in Spanish, she was Nixon's liaison to Hispanic Americans and was a member of a Cabinet committee on opportunities for Spanish-speaking people. In 1973, a young Karl Rove, then on his way to becoming the chairman of the College Republicans, suggested in a memorandum to Armstrong that the Republican Party show nonpolitical films (such as John Wayne movies and Reefer Madness) at College Republican clubs as part of a strategy to raise support for the party among students and for fundraising.
