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.

[EX Q]: 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.

[EX Q]: Question: What countries signed the treaty that acknowledges Ireland's "traditional policy of military neutrality"? Passage:Ireland has been neutral in international relations since the 1930s. The nature of Irish neutrality has varied over time, and has been contested since the 1970s. Historically, the state was a "non-belligerent" in the Second World War (see Irish neutrality during World War II) and has never joined NATO, although during the Cold War it was anti-communist and aloof from the Non-Aligned Movement. The compatibility of neutrality with Ireland's membership of the European Union has been a point of debate in EU treaty referendum campaigns since the 1990s. The Seville Declarations on the Treaty of Nice acknowledge Ireland's "traditional policy of military neutrality", reflecting the narrow formulation of successive Irish governments. Others define Irish neutrality more broadly, as having "a strong normative focus, with a commitment to development, United Nations peacekeeping, human rights and disarmament".

[EX Q]: Question: How long was Heisman head coach at Auburn? Passage:During those two years Warner also played two games against John Heisman, another future coaching legend. Heisman was the head coach at Auburn University, and they faced each other in the 1895 and 1896 games of the "Deep South's Oldest Rivalry," an annual confrontation which has continued to the present day. In 1895, the Auburn Tigers defeated the Bulldogs 126. The Auburn team was led by quarterback Reynolds "Tick" Tichenor, known for his punt returns. Tichenor had executed the first "hidden-ball trick" in an earlier Auburn game against Vanderbilt, and used it again against Georgia. The next year, Tichenor faced Georgia's Richard Von Albade Gammon, a star quarterback in his first year under Warner. Both quarterbacks played well and, unlike the previous year, Warner's team won 166. The second touchdown came right after the first onside kick in the South.
