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: In what era did the architectural style of Ince Blundell Hall emerge?  Passage:Ince Blundell Hall is in Georgian style. It is constructed in brick with sandstone dressings, and has an L-shaped plan. The main block faces southeast; it is in two storeys with an attic, and has a front of nine bays. Richard Pollard and Nikolaus Pevsner describe the front as being in late English Baroque style, and consider that it was "evidently inspired" by the front of Buckingham Palace, London. Between the upper storey and the attic is an entablature with a cornice and a panelled parapet. The central three bays project forward, the lower storeys are flanked by pairs of giant pilasters, and at the sides of the central doorway are giant columns. There are more pilasters at the ends of the building, and in the central three bays of the attic. All the pilasters and columns are Corinthian in style. The windows are sashes and are surrounded by architraves. The ground floor windows in the central bays have segmental heads with keystones, and those in the outer bays have friezes and pediments carried on consoles. Below the upper floor windows are panelled aprons and consoles. The central doorway has a segmental head and a keystone carved with the Blundell arms. At the corners of the front are quoins.
