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: Which team won the Rose Bowl the year that Vols lost the Orange Bowl? Passage:The 1997 Tennessee Volunteers football team represented the University of Tennessee during the 1997 NCAA Division I-A football season. Quarterback Peyton Manning had already completed his degree in three years, and had been projected to be the top overall pick in the 1997 NFL Draft, but returned to Tennessee for his senior year. The Volunteers opened the season with victories against Texas Tech and UCLA, but for the third time in his career, Manning fell to Florida, 33–20. The Vols won the rest of their regular season games, finishing 10–1, and advanced to the SEC Championship Game against Auburn. Down 20–7, Manning led the Vols to a 30–29 victory. Throwing for four touchdowns, he was named the game's MVP, but injured himself in the process. The #3 Vols were matched up with #2 Nebraska in the Orange Bowl. Had Tennessee won and top-ranked Michigan lost to Washington State in the Rose Bowl, the Vols would have been expected to win the national championship. However, the Vols' defense could not stop Nebraska's rushing attack, giving up more than 400 yards on the ground in a 42–17 loss. As a senior, Manning won numerous awards. He was a consensus first-team All-American and won the Maxwell Award, the Davey O'Brien Award, the Johnny Unitas Award, and the Best College Football Player ESPY Award, among others. However, he did not win the Heisman Trophy, finishing runner-up to Charles Woodson, a CB from Michigan, and the only defensive player ever to win the Heisman Trophy.

Example Input: Question: How long had FIU Stadium been standing for the year Straker played in a game against Honduras there? Passage:In May 2011, he was called up for the Grenadian national team for the upcoming CONCACAF Gold Cup. Straker played in two pre-tournament friendlies, including his debut in a 2–2 home draw with Antigua and Barbuda on 27 May 2011. He made his competitive debut for Grenada in their first match in the Gold Cup, a 4–0 loss to Jamaica at the Home Depot Center on 6 June 2011. Straker played in their two remaining group stage fixtures, a 7–1 defeat to Honduras at the FIU Stadium on 10 June 2011 and a 4–0 defeat to Guatemala at the Red Bull Arena on 13 June. He played in Grenada's three 2012 Caribbean Cup qualification second round matches, although they missed out on qualifying for the tournament after finishing in third place in their group on goal difference. He scored his first international goal with a 33rd-minute penalty kick in Grenada's 3–1 home defeat to Haiti in a 2018 FIFA World Cup qualifier on 4 September 2015.

Example Input: Question: How many years did Pietro Pellegri attend the Genoa youth academy? Passage:Born in Genoa, Pellegri is a youth product of the Genoa youth academy. On 22 December 2016, he made his debut with the senior team in Serie A in a 1–0 away loss against Torino, coming on as an 88th-minute substitute for Tomás Rincón. At the age of 15 years and 280 days, he equalled the record as the youngest ever Serie A debutant, held by Roma's Amedeo Amadei since 1937. In doing so he also became the first player born in the 21st century to appear in Serie A, and the second player born in the 2000s to make his Italian top-flight debut after Moise Kean. On 28 May, he scored his first Serie A goal in a 3–2 away loss against Roma, becoming the first player born in the 21st century to ever score in Serie A, and the third youngest goalscorer ever in the Italian top flight, after Amadei and Gianni Rivera.
