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: In what city did Harry Newman go to college? Passage:The 1935 NFL Championship Game was held on December 15, 1935, at University of Detroit Stadium (some sources call it Titan Stadium) in Detroit. The game was played in a snowstorm in front of 12,000 spectators. It was the 3rd annual title game for the NFL. The champion of the Western Division was the Detroit Lions (7–3–2) and the champion of the Eastern Division was the New York Giants (9–3). On the opening drive of the game, the Lions Glenn Presnell threw a 36-yard pass to Frank Christensen, and Ace Gutowsky threw another long pass to Ed Klewicki at the Giants' 8-yard line. Gutowsky then ran the ball into the end zone to give the Lions a 7–0 lead. The Lions scored again after Christensen intercepted a pass thrown by New York's Ed Danowski and ran it back to midfield. Three plays later, Dutch Clark ran 40 yards for a touchdown. In the fourth quarter, the Lions blocked a punt, and George Christensen recovered the ball on the Giants' 22-yard line. Ernie Caddel ran the ball in from the one-yard line for the Lions' third touchdown. The Lions added to their lead late in the game after Parker intercepted a pass from New York quarterback (and former University of Michigan star) Harry Newman on the Giants' 45-yard line and returned it to the nine-yard line. Buddy Parker ran for the touchdown as the Lions won the championship by a final score of 26–7.

Example Input: Question: What were the names of the parents of the musician Bolland particularly embraced? Passage:Growing up as "and only child in a house without culture," (Bolland says that his "mother and father had no use for art, literature or music"), he embraced the late 1960s pop culture explosion of "pirate radio stations, music (particularly Frank Zappa...), drug taking, psychedelia, "peace and love," "dropping out," the underground scene, Oz Magazine," and other aspects of hippy culture epitomised by underground comix such as Robert Crumb's Zap Comix. Having taken both O-Level and A-Level examinations in art, Bolland spent five years at art school (starting in 1969) learning graphic design and Art history. Learning to draw comics, however, was "more a self-taught thing," with Bolland eventually writing a 15,000-word dissertation in 1973 on Neal Adams – an "artist [his teachers] had never heard of." He would later recall:

Example Input: Question: What country is Gasaton Cros' birthplace now found? Passage:Colonel Marie Augstin Gaston Cros (known as Gaston Cros) (6 October 1861 – 10 May 1915) was a French army officer and archaeologist. He was born in Alsace and was displaced when that territory was incorporated into the German Empire. He joined the French Army as a lieutenant and saw action in Tonkin before spending several years surveying in Tunisia, receiving the honours of membership of Vietnamese and Tunisian orders and appointment as a chevalier of the Legion of Honour. In 1901 Cros was appointed head of the French archaeological expedition to Girsu, Iraq to continue the work of Ernest de Sarzec. His work over the next five years included the tracing of the thick city wall and for his work there received a letter of commendation from Gaston Doumergue, the Minister of Fine Arts, and the award of the Golden Palms of the Ordre des Palmes Académiques. Promoted to lieutenant-colonel, Cros served in the French protectorate of Morocco from 1913, seeing action in the Zaian War.
