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.

Input: Consider 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 Couriers 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.

He then received conversion training to the then new Messerschmitt Me 262 jet fighter and was posted to Jagdgeschwader 7 (JG77th Fighter Wing), an all-jet fighter wing.
