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 old was Sophie Okonedo the year that she appeared as Liz 10, in the episodes "The Beast Below" and "The Pandorica Opens"? Passage:Although Scream of the Shalka continues the narrative of the original 1963–89 programme and the 1996 television film, the show's 2005 revival ignored its events. The series was scripted by veteran Doctor Who writer Paul Cornell, with Richard E. Grant providing the voice for the Ninth Doctor. This performance followed years of rumours that Grant would play the Doctor in a film or new series, and indeed he had appeared as the "Conceited Doctor" in the Comic Relief special Doctor Who and the Curse of Fatal Death in 1999. Grant subsequently went on to appear in the revived television series of Doctor Who as a guest villain in 2012's "The Snowmen" and 2013's "The Bells of Saint John" and "The Name of the Doctor". The Doctor's companion for this adventure, Alison Cheney, was voiced by Sophie Okonedo who a year later would be nominated for an Academy Award for her performance in Hotel Rwanda. She also appeared in the 2010 series of Doctor Who, as Liz 10, in the episodes "The Beast Below" and "The Pandorica Opens". Derek Jacobi reprised his role as the Master in 2007's "Utopia". David Tennant appeared in a cameo role as the Caretaker, later being cast as the Tenth Doctor in 2005.

Example Input: Question: How long after the construction of the cathedral where Rachel Treweek became the 41st Bishop was she installed there? Passage:On 26 March 2015, it was announced that Treweek was to become the next Bishop of Gloucester, the diocesan bishop of the Diocese of Gloucester. Though there had been two women appointed bishops previously in the Church of England, she was the first woman to be appointed a diocesan bishop, rather than as a suffragan bishop. She was the first woman to become a bishop in the Province of Canterbury, jointly with Sarah Mullally, Bishop of Crediton. On 15 June 2015, her election was confirmed during a sitting of the Arches Court of Canterbury at St Mary-le-Bow, City of London. At this point, she legally became the Bishop of Gloucester. On 22 July 2015, she was consecrated a bishop by Justin Welby, the Archbishop of Canterbury, during a ceremony at Canterbury Cathedral. She and Sarah Mullally (later Bishop of London) were the first women to be ordained as bishops at Canterbury Cathedral. On 19 September, she was installed at Gloucester Cathedral as the 41st Bishop of Gloucester.

Example Input: Question: Was the bassist that he collaborated with in 2000 born in Tennessee? Passage:Gregory E. Stinson, better known as G. E. Stinson (born in Kingfisher, Oklahoma), is an American guitarist and founding member of new age/electronic musical group Shadowfax. Inspired by blues masters such as Bo Diddley and Muddy Waters, Stinson experimented with blues, jazz and other musical genres before co-founding Shadowfax in 1974. He remained with the band for six albums. He departed Shadowfax after recording The Odd Get Even (1989), entering the Los Angeles underground music community to refine his 'extended technique' and 'frequency manipulation'. Since then he has worked with a number of musicians on various projects, including Napalm Quartet, Splinter Group, Stinkbug, Metalworkers, Alex De Grassi, Devin Sarno and others. In 2000, he collaborated with drummer Gregg Bendian, violinist Jeff Gauthier, and bassist Steuart Liebig on an album of collective improvisational pieces recorded live in the studio, entitled Bone Structure. Released in 2003, it was given four stars by Jim Andrews in DownBeat magazine.
