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: What was the Garland Fund used for? Passage:Vann stirred up controversy and 10,000 new readers by hiring George Schuyler in 1925, whose editorials and opinions made him famous as the "black H.L. Mencken" (who was a Courier subscriber). Under Vann, the Courier also worked as a tool for social progress. Most significantly, the paper extensively covered the injustices on African Americans perpetrated by the Pullman Company and supported the Brotherhood of Sleeping Car Porters. Vann wrote to gain support for causes such as improved housing conditions in the Hill District, better education for black students, and equal employment and union opportunities. However, Vann often used his Courier editorials to publicly fight with the National Association for the Advancement of Colored People (NAACP) and W. E. B. Du Bois over issues such as President Calvin Coolidge's grants of clemency to black soldiers involved in the Houston Riot and Vann's allegations that James Weldon Johnson embezzled money for personal use from the NAACP and the Garland Fund. This disharmony was resolved in 1929 by published apologies by Vann, Du Bois, and Johnson, and within the decade, Du Bois became a regular Courier contributor. But in 1938, Vann's Courier ended up at odds with the NAACP once again. Vann, through national campaigns and contact with President Franklin D. Roosevelt pursued inclusion of African-American units in the United States Armed Forces. Vann saw this as an achievable step on the path to integration of the military, but the NAACP leadership, primarily Walter White, publicly disagreed with this half-measure, despite the protests of Thurgood Marshall. As a result of the Courier′s influence and Vann's political clout, New York Congressman Fish successfully added an amendment prohibiting racial discrimination in selection and training of men drafted to the Selective Training and Service Act of 1940.

Example Input: Question: How many years after the Clairvaux was found, was the Margam Abbey founded? Passage:The abbey was founded in 1147 as a daughter house of Clairvaux by Robert, Earl of Gloucester, and was dedicated to the Blessed Virgin Mary. Early Christian crosses found in the close vicinity and conserved in the nearby Margam Stones Museum suggest the existence of an earlier Celtic monastic community. The founding abbot was William of Clairvaux. The third abbot, Conan, enjoyed the praise of Giraldus Cambrensis, whom he appears to have entertained prior to his official visit with Baldwin of Forde, Archbishop of Canterbury, to preach the Crusade in 1188. Conan (or Cunan) contributed to Patristic literature, as he is credited with the capitula or chapter-headings prefixing each section of St. Bernard's Sermons on the Song of Songs, one of the works for which that author was titled a Doctor of the Church.

Example Input: Question: What martial arts does the man who Ken had a rivalry with after Jeff Jarrett participate in? Passage:After losing to Undertaker, Shamrock, Big Show, Mankind and Test formed The Union, a stable of wrestlers in opposition to the Corporate Ministry. The Union dissolved soon after defeating the Corporate Ministry at Over the Edge in May. Shamrock briefly feuded with Jeff Jarrett before beginning a rivalry with martial artist Steve Blackman that saw he and Blackman fight one another in a series of unorthodox matches. The feud ended at SummerSlam, where Shamrock defeated Blackman in a "Lion's Den weapons match". He went on to feud with the newly debuted Chris Jericho until departing the WWF in late 1999 in order to resume his mixed martial arts career. His departure was attributed on screen to an injury inflicted by Jericho's bodyguard, Mr. Hughes. Ken Shamrock has since appeared in the video games WWF SmackDown!,  (in Royal Rumble matches only), WWF No Mercy, WWE '13 and WWE 2K16.
