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: 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 large was the endowment at Durham University the year that Mitchell started attending the school? Passage:Mitchell was born in London, and educated at Brightlands Preparatory School and Dulwich College, London. In 1943 he registered as a conscientious objector and his war-time service was spent in the Non-Combatant Corps. After the war, he taught at Oakfield Preparatory School, London and in 1947 founded and edited the journal Music Survey; several issues appeared before he was joined in 1949 by Hans Keller and the journal was re-launched in the Music Survey's so-called 'New Series' (1949–52), whose uncompromising critical standards and pugnaciously pro-Britten and pro-Schoenberg stance brought it renown and notoriety in equal measure. Mitchell studied at Durham University 1949-50. In the 1950s he was a regular contributor to the journals Musical Times and Musical Opinion. In 1958 he became editor of Music Books at Faber and Faber and in the same year was appointed Editor of Boosey & Hawkes's music journal Tempo, until 1962. From 1963 to 1964 he was a special music adviser at Boosey & Hawkes with particular responsibility for contemporary music and the acquisition of contemporary composers. He was responsible for Peter Maxwell Davies and Nicholas Maw joining the publisher's list. In 1965, with the encouragement of Benjamin Britten he founded the music-publishing firm of Faber Music, and was its first Managing Director (vice-chairman, 1976, chairman, 1977, president, 1988–95). In 1972 he became the first Professor of Music at Sussex University (until 1976). Following the death of Benjamin Britten, Mitchell became a senior trustee of the Britten-Pears Foundation; in 1986 he became the Foundation's director and chairman of the Britten Estate Ltd. From 1989 to 1992 he was chairman of the Performing Right Society. He was appointed a CBE in the 2000 New Year Honours, and died on 28 September 2017.

Example Input: Question: What is the difference between the two types of cloth England was famous for in the 18th century? Passage:In the 18th century, England was famous for its woollen and worsted cloth. That industry, centred in the east and south in towns such as Norwich, jealously protected their product. Cotton processing was tiny: in 1701 only of cottonwool was imported into England, and by 1730 this had fallen to . This was due to commercial legislation to protect the woollen industry. Cheap calico prints, imported by the East India Company from Hindustān (India), had become popular. In 1700 an Act of Parliament passed to prevent the importation of dyed or printed calicoes from India, China or Persia. This caused demand to switch to imported grey cloth instead—calico that had not been finished—dyed or printed. These were printed with popular patterns in southern England. Also, Lancashire businessmen produced grey cloth with linen warp and cotton weft, known as fustian, which they sent to London for finishing. Cottonwool imports recovered though, and by 1720 were almost back to their 1701 levels. Again the woollen manufacturers, in true protectionist fashion, claimed that the imports were taking jobs away from workers in Coventry. The Woollen, etc., Manufactures Act 1720 was passed, enacting fines against anyone caught wearing printed or stained calico muslins. Neckcloths and fustians were exempted. The Lancashire manufacturers exploited this exemption; coloured cotton weft with linen warp were specifically permitted by the 1736 Manchester Act. There now was an artificial demand for woven cloth.
