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: How many years after Wish You Were Here was released was The Wall released? Passage:Storm Thorgerson, who had done the majority of album covers for Pink Floyd, did the Echoes art which features recursive windows in an infinite regression as a nod to his own cover for 1969's Ummagumma, and the objects on each landscape refer to the Pink Floyd discography. For instance, there's the man on fire from Wish You Were Here, another wearing the Delicate Sound of Thunder lightbulb suit, dolls of the Atom Heart Mother cow and the Animals pig, a bike and both a brick wall and the hammers from The Wall. Eventually Thorgerson opted to make two images, with another used for the back cover. To create the idea on a photograph, various walls - which had varied measurements and angles to ensure that "nothing seemed to fit other than by eye through the lens." - were built and put in a country landscape in Sussex. Actors, props and fittings were set in and between those walls. The original design was one of two sketches submitted for Dream Theater's 1997 album Falling into Infinity, with the original being framed and hanging in the home of former Dream Theater drummer Mike Portnoy and is pointed out by Portnoy in his Hudson Music instructional drum DVD In Constant Motion.

Example Input: Question: Did the quarterback who threw a 52-yard touchdown pass to Mike Young during the 1984 Rose Bowl ever become a professional football player in the NFL? Passage:The Visalia, CA native was a multi-sport athlete at Mt. Whitney High School where he excelled in football and baseball. Michael's career statistics of 162 catches for 3,005 yards and 44 touchdowns still stand as one of the top performances in CIF history. Young was recruited by every major college football program in the Country, accepting recruiting visits to Notre Dame, USC, Nebraska, Oklahoma, Washington and UCLA. At UCLA, he played both football and baseball. Young helped the Bruins to two Pac-10 titles, two Rose Bowl (1983, 1984) victories and a Fiesta Bowl (1985) win. Michael was an Academic All-Pac 10 selection in 1984 and in the 1984 Rose Bowl game, Young had 5 receptions for a total of 127 yards, including a 52-yard touchdown pass from Rick Neuheisel. As a two-sport athlete, Young was drafted by the New York Mets in 1983 after hitting .311 his sophomore year. Following the 1985 Fiesta Bowl win, in which he was the leading receiver, he was drafted by the Los Angeles Rams. He earned a bachelor's degree in sociology from UCLA.
