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.

Input: Consider Input: Question: How old was Walt Disney the year Snow White and the Seven Dwarfs was released? Passage:After the success of Walt Disney Productions' first feature-length animated film Snow White and the Seven Dwarfs (1937), filmmaker Walt Disney himself made several attempts to adapt the fairy tale "Beauty and the Beast" by Jeanne-Marie Leprince de Beaumont into one of the studio's earliest animated feature films during the 1930s and 1950s. However, the project was continuously abandoned due to the fairy tale's "static" plot and main characters. The filmmaker was also concerned about the "unnecessary intensity" required to depict Belle's imprisonment. Inspired by the unprecedented success of The Little Mermaid (1989), Walt Disney Studios chairman Jeffrey Katzenberg green-lit another attempt at adapting "Beauty and the Beast" under the direction of Richard Purdum. However, Katzenberg did not approve of Purdum's dark, somber version of the fairy tale, and ultimately ordered that it be restarted from scratch in favor of creating a Broadway-style musical film starring a strong heroine, more similar to The Little Mermaid. Opting instead for a "feminist twist" on the original story, largely in response to critics' negative reception to Ariel regarding her pursuit of Eric being her overall character, Katzenberg hired television writer Linda Woolverton, who had never written an animated film before, to write the film's screenplay.

Input: Consider Input: Question: Who was in charge at Princeton University the year Barschall graduated from that school? Passage:Barschall was born as Heinrich Hermann Barschall in Berlin, Germany; his father was a patent attorney who had received a Ph.D. in chemistry after studying with Nobel Laureates Emil Fischer and Fritz Haber. After beginning study in several universities in Germany, he emigrated to the United States in 1937 during the early Holocaust period; though raised as a Lutheran, he had some Jewish ancestry. He received his Ph.D. from Princeton University in 1940 under the direction of Rudolf Ladenburg; he also worked closely with John A. Wheeler. After a suggestion by Niels Bohr, he carried out in only a few days with fellow graduate student Morton H. Kanner the first demonstration of fission by fast neutrons and thorium and uranium. His thesis was on the interaction of fast neutrons with helium. In a paper with John A. Wheeler he reported the discovery of spin-orbit coupling in neutron scattering.

Input: Consider Input: Question: What years were World War II fought? Passage:There is a great deal written in music history books about the period of artistic experimentalism after World War II in Europe and the United States. Much like the period in France after the Franco-Prussian War (Impressionism) and in the late 19th century, the pre/post World War I period of (Expressionism), the post World War I period of Modernism was no different with composers trying to 'write music for the sake of music' and not attaching it to a social meaning or meant for a social cause (see Darmstadt School). The LP City of Glass and the whole body of work from the Stan Kenton orchestra and Robert Graettinger (19471953) is a direct product of the experimental American music scene of the post World War II era. Though overshadowed historically by other compositional endeavours in jazz at the time attributed to George Russell, Neal Hefti or Lennie Tristano, Graettinger and City of Glass is important in the progress that was to be part of Third stream jazz.
