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: Of the two players who each scored first for Brazil and Chile, whose birthday falls earlier in the year? Passage:Brazil faced Chile in the round of 16, taking an 18th-minute lead through David Luiz's first goal for the Seleção. With no further scoring after Alexis Sánchez's equaliser, the match went to a penalty shootout. Brazil prevailed 3–2, with Neymar, David Luiz and Marcelo converting their kicks, and goalkeeper Júlio César saving from Chileans Sánchez and Mauricio Pinilla. The team again faced South American opposition in the quarter-final, defeating Colombia 2–1 with goals from central defenders David Luiz and team captain Thiago Silva. Late in the match, Neymar was substituted on a stretcher after Camilo Zúñiga's knee had made contact with the forward's back. Neymar was taken to hospital and later diagnosed with a fractured vertebra, which ruled him out for the remainder of the tournament. Prior to this, Neymar had scored four goals, provided one assist and been named man of the match twice. Brazil faced further problems ahead of their semi-final against Germany, as Thiago Silva was to serve a one-match suspension for receiving his second yellow card of the tournament in the quarter-final. The Seleção went on to lose 1–7 to the Germans, their biggest ever defeat at the World Cup and first home loss in a competitive match since 1975. Towards the end of the match, the home crowd began to "olé" each pass from the German team, and booed their own players off the pitch after the final whistle. The match has been nicknamed the Mineirazo, making reference to the nation's previous World Cup defeat on home soil, the Maracanazo against Uruguay in 1950, and the Estádio do Mineirão in Belo Horizonte where the match took place.

Example Input: Question: How many teams are in the leagues which compete for the cup annually? Passage:In 2002, the International Ice Hockey Federation (IIHF) announced that it would acknowledge the site of Victoria Rink with "a commemorative plaque or other historical site marker to remind the passers-by of the existence of the Victoria Skating Rink, the birthplace of organized hockey." The commemoration has been marked in two ways. On May 22, 2008, a commemorative plaque was dedicated at the nearby Centre Bell, along with a plaque honouring James Creighton. Further, the IIHF created the Victoria Cup, a trophy named for the arena, for which—along with 1 million Swiss francs—one National Hockey League team and the champion of the European Champions Hockey League play-off annually. The first Cup match was held in Berne, Switzerland on October 1, 2008 between the New York Rangers and the Metallurg Magnitogorsk. The next, and last, edition of the Victoria Cup was held in Zurich on September 29, 2009, between the ZSC Lions and the Chicago Blackhawks.

Example Input: Question: How many NCAA football championships have been won by the college that Peyton Manning attended? Passage:In 1998 the Colts, for the 4th time in 15 years, held the 1st overall pick in the draft and for the 3rd time in 15 years selected a quarterback – this time University of Tennessee's Peyton Manning. Manning started the first game of his rookie season and started every single Colts game since until the start of the 2011 season, when a recurring neck injury sidelined him. Despite a difficult rookie season, where he threw a league high 28 interceptions, Manning and the Colts responded by finishing 13–3 in 1999. The 10 game turnaround from the previous year set an NFL record. Even with this turnaround, the Colts lost in the playoffs. The following years would be marked by a near constant pattern. The Colts and Manning successes in the regular season were matched only by their failures in the post season. Manning was named to the Pro Bowl in 1999, 2000, 2002, 2003 and 2004, as well as winning the NFL MVP award in both 2003 and 2004. In 2004 Manning set a then NFL record when he threw 49 touchdowns in a single season. In spite of this the team failed in the playoffs, including early round exits in 1999, 2000, 2002 and 2005. In both 2003 and 2004 the Colts would lose to eventual Super Bowl winning New England Patriots in the AFC Championship Game and the Divisional Round respectively. In 2006 the Colts and Manning were finally able to beat the Patriots and their quarterback Tom Brady in the AFC Championship Game on their way to a victory in Super Bowl XLI against the Chicago Bears. Manning was named the Super Bowl MVP. The Colts and Manning would continue to have success, with Manning winning two further MVP awards in 2008 and 2009. In 2009 the Colts would return to the Super Bowl where they would lose to the New Orleans Saints.
