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: When was the team Tuqiri last played for founded? Passage:Lote Daulako Tuqiri (born 23 September 1979) is a Fijian-Australian former professional dual-code rugby footballer who last played for the South Sydney Rabbitohs in the NRL. He represented Australia in both rugby league and rugby union, and Fiji in rugby league. He usually played as a winger in both codes. Tuqiri first rose to prominence as a professional rugby league footballer for the Brisbane Broncos and Queensland Maroons, as well as the Fiji and Australia national sides. He was therefore a high-profile signing for rugby union in 2002, winning 67 caps for Australia and being a part of their 2003 and 2007 World Cup squads. He played rugby union for the Waratahs in the Super 14 and Leicester Tigers in England in season 2009–10. Tuqiri's contract with the Australian Rugby Union was terminated on 1 July 2009. No immediate reason was given, and Tuqiri returned to rugby league in 2010, playing for the Wests Tigers of the NRL. In September 2013, he signed a short-term contract with Irish rugby union giants, Leinster to play in the Pro12 in a three-month deal. Just 6 weeks out from the 2014 NRL season, Tuqiri signed with his third NRL club, the South Sydney Rabbitohs on a one-year deal.

Example Input: Question: How old is the team that beat the 1985 Bears? Passage:The Bears won fifteen games, as the 49ers had the year before, and won their first twelve before losing to the Miami Dolphins to deny a perfect season. The Bears' defense was ranked first in the league and only allowed 198 total points (an average of 12.4 points per game). The Bears won the NFC Central Division by seven games over the second place Green Bay Packers and earned the NFC's top seed and home field advantage throughout the playoffs at Soldier Field. In their two playoff games against the New York Giants and Los Angeles Rams, the Bears outscored their opponents 45–0 and became the first team to record back-to-back playoff shutouts. Then, in Super Bowl XX in New Orleans against the New England Patriots, the Bears set several more records. First, their 46 points broke the record that had been set by the Los Angeles Raiders in 1984 with 38 and tied by the 49ers the following year. Their 36-point margin of victory topped the 29-point margin of victory that the Raiders had put up in Super Bowl XVIII and stood as a record until the 49ers won Super Bowl XXIV, also in New Orleans, by 45 points over the Denver Broncos. It was the Bears' first NFL World Championship title since 1963.

Example Input: Question: What is the oldest band that Ethan Luck had previously worked with in 2005? Passage:In 2003 they took a short break, during which McCaddon decided to leave Society's Finest, and went on to join Demon Hunter. After leaving Society's Finest and Embodyment, Ryan Clark and Don Clark, formerly of Training for Utopia, recruited him, Jesse Sprinkle, formerly of Poor Old Lu, and Jon Dunn (Who would later join Soul Embraced) to join their project, Demon Hunter. Demon Hunter already had an album before he joined. On this album McCaddon had contributed by photography. On his Demon Hunter debut, Summer of Darkness, was great success. In 2005, Ethan Luck, formerly of The O.C. Supertones and Project 86, replaced McCaddon. In 2006, former Embodyment members, Mark Garza (drums) and Andrew Godwin (guitar), contacted McCaddon and said they wanted to play metal again. McCaddon contacted former Society's Finest member, Nick Nowell (bass) and asked him to join their new project, The Famine. Though McCaddon knew people would compare the Famine to Embodyment, he stated that "We started The Famine because we wanted to get away from the stuff we were playing with Embodyment...".
