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: How many members did No. 11 Group have during the years of the Blitz? Passage: the Second World War, the station was very active during the Battle of Britain and the Blitz in 1940–41 in No. 12 Group (controlled from RAF Watnall in Nottingham) as it was the main fighter station for a lot of the southern East Midlands, and fighters from the station would often patrol as far as Birmingham. During the Battle of Britain many squadrons were rotated through Wittering to spells in the south of England with No. 11 Group that was bearing the brunt of the battle. With many of the Luftwaffe raids during the Blitz taking part at night, Wittering-based squadrons were instrumental in the development of night combat techniques. These included the use of the Turbinlite aircraft which replaced the nose with a powerful searchlight insulated in the nose of Havocs and Bostons. In April 1943 No. 141 Squadron were moved in, operating de Havilland Mosquitoes. 1943 also saw the station host 2 USAAF squadrons, albeit temporarily: 63 Fighter Squadron USAAF with its P47s operated from Wittering between January and March before moving to RAF Horsham St Faith; 55 Fighter Squadron operated its P38s and P51s from Wittering between August and March 1944 before moving to nearby RAF Kingscliffe.

Example Input: Question: How old was Norimasa kaeriyama when he directed The Glow of Life? Passage:Among intellectuals, critiques of Japanese cinema grew in the 1910s and eventually developed into a movement that transformed Japanese film. Film criticism began with early film magazines such as Katsudō shashinkai (begun in 1909) and a full-length book written by Yasunosuke Gonda in 1914, but many early film critics often focused on chastising the work of studios like Nikkatsu and Tenkatsu for being too theatrical (using, for instance, elements from kabuki and shinpa such as onnagata) and for not utilizing what were considered more cinematic techniques to tell stories, instead relying on benshi. In what was later named the Pure Film Movement, writers in magazines such as Kinema Record called for a broader use of such cinematic techniques. Some of these critics, such as Norimasa Kaeriyama, went on to put their ideas into practice by directing such films as The Glow of Life (1918), which was one of the first films to use actresses (in this case, Harumi Hanayagi). There were parallel efforts elsewhere in the film industry. In his 1917 film The Captain's Daughter, Masao Inoue started using techniques new to the silent film era, such as the close-up and cut back. The Pure Film Movement was central in the development of the gendaigeki and scriptwriting.
