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'.

Example Input: Question: How many seasons did the television show that Earl Gaines appeared on air?  Passage:Breaking away from the confines of the group, Gaines became part of the 1955 R&B Caravan of Stars, with Bo Diddley, Big Joe Turner, and Etta James. Their tour culminated with an appearance at New York's Carnegie Hall. Without any tangible success, Gaines recorded for the Champion and Poncello labels for another few years, as well as joining Bill Doggett's band as lead vocalist. In 1963, he joined Bill "Hoss" Allen's repertoire of artists, and by 1966 had issued the album The Best of Luck to You, seeing the title track reach the Top 40 in the US R&B chart. He appeared on the television program The !!!! Beat, and later released material for King and Sound Stage 7, including his cover version of "Hymn Number 5". Recordings made between 1967 and 1973 for De Luxe were reissued in 1998. On many of his De Luxe recordings in the late 1960s and early 1970s, Gaines was backed by Freddy Robinson's orchestra.

Example Input: Question: What war were the boats like Kennedy was on used in? 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."
