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: In what year did Jordan Roth buy 50% of Jujamcyn? Passage:Landesman was born and raised in St. Louis, Missouri, studied at Colby College and then the University of Wisconsin, Madison (BA English Literature 1969), and the Yale School of Drama (MFA Dramatic Literature and Criticism 1972, DFA 1976). At the Yale School of Drama he became a protégé and friend of Robert Brustein. At the completion of his course work he stayed at Yale for four years as an Assistant Professor. While at Yale, Landesman got to know novelist Jerzy Kosinski and he worked with Kosinski on two of his novels, Being There and The Devil Tree. Landesman was involved as an editor, helping Kosinski, not a native speaker of English, with his English syntax and writing. While at Yale Landesman was also involved in managing a private mutual fund and a racehorse he had bought. In 1977 he left to focus more time on his private investment fund, which he ran for many years. He also got involved in Broadway theater and he was heavily involved in the genesis and development of "Big River" (1985 Tony, Best Musical), a musical based on Huckleberry Finn. Landesman's involvement included persuading Roger Miller to write the music for the show. The show ultimately won seven Tonys and ran for over 1,000 performances on Broadway over two and a half years. This success attracted the attention of James H. Binger who shared two passions with Landesman: Broadway theater and horseracing. Binger owned the Jujamcyn Theatre group of five theatres, four of which were then dark. Binger and Landesman made a deal for Landesman to become President of Jujamcyn in 1987 with the inclusion of an option for Landesman to purchase Jujamcyn upon Binger's death. After taking the helm at Jujamcyn he shifted its business model away from the historical focus of renting of theatre facilities to shows and into a more active posture as a combination of a theater owner and a developer of new plays. Other theater owners have followed this pattern. After joining Jujamcyn Landesman has produced Broadway shows, the most notable of which include: "" (1993 and 1994 Tony, Best Play), and "The Producers" (2001 Tony, Best Musical). Landesman purchased Jujamcyn in 2005 and later sold a 50% interest to Jordan Roth.

Example Input: Question: What year saw the publication of the eleventh edition of the zoological book published by a Swedish naturalist who included the hook-billed vanga in the twelfth edition of the book? Passage:In 1760 the French zoologist Mathurin Jacques Brisson included a description of the hook-billed vanga in his Ornithologie based on a specimen collected on the island of Madagascar. He used the French name L'écorcheur de Madagascar and the Latin Collurio Madagascariensis. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been previously described by Brisson. One of these was the hook-billed vanga. Linnaeus included a brief description, coined the binomial name Lanius curvirostris and cited Brisson's work. It is now the only species placed in the genus Vanga that was introduced by the French ornithologist Louis Jean Pierre Vieillot in 1816. The specific name curvirostris is from Latin curvus "curved" and -rostrum "billed". The word "vanga" is the Malagasy name for the species. Two subspecies are recognised.

Example Input: Question: Has the team Tom was drafted by in 1967 ever made it to the finals? Passage:Standing 6 ft 6 in, Meschery also was a highly talented basketball player. After graduating from St. Mary's, he was drafted by the Philadelphia Warriors as the 7th pick overall in the 1961 NBA draft. Meschery played alongside legend Wilt Chamberlain, to whom he later dedicated a poem. Meschery was the starting forward on the 1961-62 Philadelphia Warriors team in which Chamberlain scored 100 points. Meschery led the NBA in personal fouls in 1962 and he became the first foreign born player to play in an NBA All-Star Game when he played in the 1963 NBA All-Star Game. Chamberlain left the Warriors in 1965, returning to his home town Philadelphia, to play with the 76ers. The Warriors however, strengthened by the arrival of Rick Barry, made it to the 1967 NBA Finals, in which they lost to Chamberlain's 76ers. After his NBA Finals appearance, Meschery was selected by the NBA's Seattle SuperSonics during the 1967 NBA Expansion Draft.
