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: Did Charles Jones win any tests in the Caribbean? Passage:In 1930, when the MCC visited the Caribbean under the leadership of F.S.G. Calthorpe, Jones played against them three times in February, twice for British Guiana and once whilst making his Test Match debut. His selection for the 3rd Test of the four-match series, played at Bourda, Georgetown was more to do with the West Indies’ usual policy of using a few players from the host island in an effort to keep the expenses down. In an historic victory over England, Jones’ contribution was minimal, scoring just 6 and 2, taking two catches but failing to take a wicket with the ball. He played only occasionally for the next five years but aided by some useful scores with the bat in that time, Jones made a further three Test appearances against England sides led by R.E.S. Wyatt in 1935. In the second Test of the series, played at Port-of-Spain, Trinidad, and where he opened with C.M. Christiani, he scored 19 runs in both innings. This subsequently proved to be his highest Test score but he failed to take a single Test wicket in his career. In all first-class matches he took 24 wickets at an average of 44.12 apiece and scored 917 runs at an average of 21.83. In a career that ended in January 1939, his highest score was an unbeaten 89, scored at home in a comprehensive victory over Barbados. No Obituary appeared within the pages of Wisden for Jones.

Example Input: Question: Were there any famous performers at the music festival McCollum often performed at? Passage:During the mid-1950s McCollum was highly busy performing as a concert soloist and performed with some frequency in operas with the New England Opera Theatre (NEOT). He sang frequently with the Boston Symphony Orchestra under conductor Charles Munch, often at the Tanglewood Music Festival, performing works like the role of the evangelist in Bach's Johannes Passion (1956). He was also a regular performer with the Dessoff Choirs under conductor Paul Boepple, performing as a tenor soloist in oratorios like Handel's Messiah (1956) and Handel's Israel in Egypt (1957). One work which he performed with frequency during these years was J.S. Bach's Mass in B Minor, which he first performed in February 1955 with the Chicago Symphony Orchestra under conductor Margaret Hillis. He later performed the work with the Boston Symphony Orchestra at Tanglewood in the summer of 1955 and with the Philadelphia Orchestra at the Bethlehem Bach Festival in 1956. In March 1955 he sang Helenus in a lauded production of Berlioz's Les Troyens with the New England Opera Theater opposite Eunice Alberts as Cassandre, Marriquita Moll as Dido, and Arthur Schoep as Aeneas.

Example Input: Question: What is the population of the city the yeshiva fled from? Passage:When the Bolsheviks revolted, the yeshiva was forced to flee from Lithuania to Kletsk, Poland. During his three years in Kletsk, Yechiel Michel attended the famed Talmudic lectures of Rabbi Meltzer and his son-in-law, Rabbi Aharon Kotler. Then he transferred to the Mir yeshiva, where he became a leading student of Rabbi Yeruchom Lebovitz and learned together with Rabbi Yechiel Michel Schlesinger, future rosh yeshiva of Yeshivas Kol Torah in Jerusalem, and Rabbi Yonah Karpilow of Minsk, who was killed in the Holocaust and whose Yonas Eilem was published posthumously. At this time, Rabbi Chaim Shmuelevitz and Rabbi Aryeh Leib Malin also studied in the Mir yeshiva. Despite being surrounding by such luminaries in Torah, R' Yechiel Michel was nonetheless thought of as "the genius of the yeshiva".
