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: Has the the team against which Duda hit three home runs on July 29 ever played in a World Series? Passage:On July 29, during a 7–3 loss to the San Diego Padres, Duda became the eleventh Mets player to hit three home runs in a single game, and only the second Met to do so at home after Kirk Nieuwenhuis had accomplished the feat less than a month before. Duda set a Mets franchise record on August 1 when eight of his consecutive hits came in the form of home runs; he and teammate Noah Syndergaard were named National League Co-Players of the Week for the week ending on August 2. On September 26, Duda hit his first career grand slam in the Mets' 10–2 victory over the Cincinnati Reds. That victory clinched the NL East division title for the New York Mets. On the final day of the season, Duda was hit by a pitch from the Washington Nationals' Tanner Roark, giving him 14 total HBP on the season and breaking the Mets single season record, previously shared by John Olerud and Ron Hunt. For the season, he had the highest fly ball percentage (50.6%), and the lowest ground ball percentage (27.4%), of all major league hitters.

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."

Example Input: Question: What country did Crespo attend university while serving in the army? Passage:In 1970, 22-year-old Crespo had dropped out of IST and was eventually drafted into military service in the Portuguese Colonial War. He transferred to Mozambique where his military occupation was to check the cement cargoes from Beira to the Cahora Bassa Dam construction site, near Tete. Some time later, due to his good fluency in English, he was placed in the press office of Kaúlza de Arriaga, the commander in chief of the Portuguese Armed Forces in Mozambique, who had coordinated a massive anti-guerrilla operation against FRELIMO separatists in 1970 - the Gordian Knot Operation. While serving in the army, Crespo also entered the newly created School of Medicine of the University of Lourenço Marques where he would complete a number of academic disciplines but did not graduate. He also married Helen de Souza from Johannesburg, a South African woman with Portuguese ancestry who worked in genetics. After the Carnation Revolution left-leaning military coup at Lisbon in April 1974, fresh out of the troop, Crespo fled Mozambique for South Africa.
