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: How many members did No. 11 Group have during the years of the Blitz? Passage: the Second World War, the station was very active during the Battle of Britain and the Blitz in 1940–41 in No. 12 Group (controlled from RAF Watnall in Nottingham) as it was the main fighter station for a lot of the southern East Midlands, and fighters from the station would often patrol as far as Birmingham. During the Battle of Britain many squadrons were rotated through Wittering to spells in the south of England with No. 11 Group that was bearing the brunt of the battle. With many of the Luftwaffe raids during the Blitz taking part at night, Wittering-based squadrons were instrumental in the development of night combat techniques. These included the use of the Turbinlite aircraft which replaced the nose with a powerful searchlight insulated in the nose of Havocs and Bostons. In April 1943 No. 141 Squadron were moved in, operating de Havilland Mosquitoes. 1943 also saw the station host 2 USAAF squadrons, albeit temporarily: 63 Fighter Squadron USAAF with its P47s operated from Wittering between January and March before moving to RAF Horsham St Faith; 55 Fighter Squadron operated its P38s and P51s from Wittering between August and March 1944 before moving to nearby RAF Kingscliffe.

Example Input: Question: Are both football clubs that Hill's team played in the 2002-03 season FA Cup located in England? Passage:He led the club to the Isthmian League title and promotion to the Conference in his first season in charge. The following season, Hill's side finished third in the Conference and took Premiership Charlton Athletic to a replay in the Third Round of the FA Cup. They again reached the FA Cup Third Round in the 2001-02 season, losing 4-1 to Ipswich Town after taking the lead, and finished second in the Conference, missing promotion to the Football League on goal difference. The following season saw another run in the FA Cup, beating Plymouth Argyle after a replay in the Third Round before losing 1-0 to Norwich City thanks to an injury time goal. Their league form was not particularly good until the latter stages of the season when they won eleven consecutive games and qualified for the play-off final, losing 3-2 in extra-time to Doncaster Rovers. The 2003-04 season was not a success and Hill resigned soon after a 9-0 defeat at home to Hereford United late in the season.

Example Input: Question: How many seasons did the head coach from 2004 work for the Buffalo Bills? Passage:On November 30, the Bills beat the Cleveland Browns giving them their seventh win, which not only improved on the previous season, in which they finished 6-10 for the third time since 2003 (they finished 6-10 in 2009 and 2011, the latter of which after they started 5-2), but it also gives them their best start entering December since the 2000 Buffalo Bills season, in which they finished 8-8 and missed the playoffs. With a win against the Green Bay Packers on December 14, the Bills broke a league-leading streak of nine consecutive losing seasons dating back to 2005; however, the next week's 26-24 loss to the Oakland Raiders eliminated them from playoff contention for the 15th consecutive year, continuing a league-leading drought. The team finished with a 17-9 win against the New England Patriots, who were resting the starters in preparation for a playoff run; the win was the first time the team had won at Gillette Stadium (they had lost all 12 previous attempts) and established the team's first winning season since 2004 (former head coach Mike Mularkey's first season).
