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: What year did Cash record "Big Iron"? Passage:Robbins has been honored by many bands, including the Grateful Dead who covered "El Paso" and Bob Weir & Kingfish who covered "Big Iron". The Who's 2006 album Endless Wire includes the song "God Speaks of Marty Robbins". The song's composer, Pete Townshend, explained that the song is about God deciding to create the universe just so he can hear some music, "and most of all, one of his best creations, Marty Robbins." The Beasts of Bourbon released a song called "The Day Marty Robbins Died" on their 1984 debut album The Axeman's Jazz. Both Frankie Laine and Elvis Presley, among others, recorded versions of Robbins' song "You Gave Me a Mountain", with Laine's recording reaching the pop and adult contemporary charts in 1969. Though Elvis never recorded any of Robbins' songs in the studio, he was a big fan and recorded "You Gave Me a Mountain" live in concert several times; it appeared on 15 Presley albums. Johnny Cash recorded a version of "Big Iron" as part of his American Recordings series, which is included in the Cash Unearthed box set. Cash also recorded other songs by Robbins, including "I Couldn't Keep From Crying", "Kate" and "Song Of The Patriot". He held Robbins in high esteem, having him guest several times on his network TV show. "Big Iron" was also covered by Mike Ness on his album Under the Influences, on which he paid homage to country music artists. The song, originally released on Robbins' 1959 album Gunfighter Ballads and Trail Songs, gained renewed popularity following its use in the video game .

Example Input: Question: What was the first game produced by Bullfrog Productions? Passage:Peter Molyneux founded Bullfrog Productions in 1987, which was later acquired by Electronic Arts (EA) in 1995. Around 1996, Molyneux had contemplated leaving Bullfrog, as he felt limited in his creative freedom under Electronic Arts. He along with Lionhead's eventual co-founders, Mark Webley, Tim Rance and Steve Jackson, started developing plans for a new studio. In 1997, due to a series of events and from issues arising between Molyneux and Electronic Arts, he ultimately left the company in July 1997, co-founding Lionhead shortly after that, along with Mark Webley, Tim Rance, and Steve Jackson (who co-founded Games Workshop and co-authored the Fighting Fantasy series). On his recruitment, Jackson said "It was an offer I couldn't refuse", as he wanted to get back to making games instead of writing about them (Jackson had interviewed Molyneux about Bullfrog and Dungeon Keeper, but for much of it, they discussed German board games instead. This led to them meeting frequently for an event called "Games Night"). Molyneux assured him that his lack of programming knowledge was an asset rather than a problem. Lionhead is the second Bullfrog break-off group, after Mucky Foot Productions (founded in February 1997). According to Glenn Corpes (who co-founded another: Lost Toys), Lionhead was Molyneux's "take on what Bullfrog used was".

Example Input: Question: Who was Rookie of the Year the year after the person Ichiro hit a home run against? Passage:Ichiro made his NPB Pacific League debut in 1992 for the Orix BlueWave at the age of 18, but he spent most of his first two seasons in the farm system (accumulating 156 minor league hits and a .368 batting average) because his then-manager, Shōzō Doi, refused to accept Ichiro's unorthodox swing. The swing was nicknamed because of the pendulum-like motion of his leg, which shifts his weight forward as he swings the bat, and goes against conventional hitting theory. In his second career game, he recorded his first ichi-gun (Japan's Nippon Professional Baseball League) hit in the Pacific League against Hawks pitcher Keiji Kimura. Even though he hit in 1993 a home run against Hideo Nomo, who later won an MLB National League Rookie of the Year Award while a Los Angeles Dodger, Ichiro was nevertheless sent back to the farm system on that very day. In 1994, he benefited from the arrival of a new manager, Akira Ōgi, who played him every day in the second spot of the lineup. He was eventually moved to the leadoff spot, where his immediate productivity dissolved any misgivings about his unconventional swing. He set a Japanese single-season record with 210 hits, the first player ever to top 200 hits in a single season. Five other players have since done so: Matt Murton, Norichika Aoki (twice), Alex Ramírez, Tsuyoshi Nishioka, and Shogo Akiyama's 216 hits in 2015, but those players benefited from 140+ game seasons while Ichiro's 210 hits had come in a 130-game season.
