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.

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.

Question: Who was older when Heitler obtained his doctorate, Arnold Sommerfeld or Karl Herzfeld? Passage:In 1922, Heitler began his study of physics at the Karlsruhe Technische Hochschule, in 1923 at the Humboldt University of Berlin, and in 1924 at the Ludwig Maximilian University of Munich (LMU), where he studied under both Arnold Sommerfeld and Karl Herzfeld. The latter was his thesis advisor when he obtained his doctorate in 1926; Herzfeld taught courses in theoretical physics and one in physical chemistry, and in Sommerfeld's absence often took over his classes. From 1926 to 1927, he was a Rockefeller Foundation Fellow for postgraduate research with Niels Bohr at the Institute for Theoretical Physics at the University of Copenhagen and with Erwin Schrödinger at the University of Zurich. He then became an assistant to Max Born at the Institute for Theoretical Physics at the University of Göttingen. Heitler completed his Habilitation, under Born, in 1929, and then remained as a Privatdozent until 1933. In that year, he was let go by the university because he was Jewish.

Question: Is the head coach of the team that Ole Miss beat in the Sugar Bowl married? Passage:Ole Miss's 2015 season began with easy victories over FCS foe UT-Martin and the Mountain West's Fresno State, and continued their momentum by defeating then-no.2 Alabama on the road, which would become the signature victory of the Rebels' 2015 campaign. Ole Miss then rose to no.3 in the AP Poll, and although they were heavy favorites in their next matchup against Vanderbilt, they struggled mightily, but ultimately emerged victorious. They Rebels maintained their no.3 ranking before getting blown out by Florida on the road and fell to no.14 before bouncing back against New Mexico State. The Rebels entered their next game with a #13 ranking against rival Memphis, in what was one of the most anticipated in the history of Memphis football. Ole Miss, despite being double digit favorites, lost by 13 points, causing them to fall 11 spots in the rankings to no.24. The Rebels followed with two wins against SEC West opponents Texas A&M and Auburn and climbed to no.18 in the rankings and controlled their own destiny the SEC West, but a heartbreaking loss to Arkansas the following week caused them to fall to second place in the SEC West and to fall out of the rankings for the first time since the 2013 season. However, Ole Miss finished the regular season with double digit wins over ranked SEC Rivals LSU and Mississippi State and rose to no.12 in the College Football Playoff poll, which earned them a Sugar Bowl berth for the first time since 1970, where they defeated no.16 Oklahoma State and ultimately finished ranked no.10 in the AP Poll, their first top-ten finish since 1969.
