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: Did other scientists keep blending inheritance open for further consideration? Passage:In the preface, Fisher considers some general points, including that there must be an understanding of natural selection distinct from that of evolution, and that the then-recent advances in the field of genetics (see history of genetics) now allowed this. In the first chapter, Fisher considers the nature of inheritance, rejecting blending inheritance, because it would eliminate genetic variance, in favour of particulate inheritance. The second chapter introduces Fisher's fundamental theorem of natural selection. The third considers the evolution of dominance, which Fisher believed was strongly influenced by modifiers. Other chapters discuss parental investment, Fisher's geometric model, concerning how spontaneous mutations affect biological fitness, Fisher's principle which explains why the sex ratio between males and females is almost always 1:1, reproductive value, examining the demography of having girl children. Using his knowledge of statistics, the Fisherian runaway, which explores how sexual selection can lead to a positive feedback runaway loop, producing features such as the peacock's plumage. He also wrote about the evolution of dominance, which explores genetic dominance. The last five chapters (8-12) include Fisher's more idiosyncratic views on eugenics.
