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.

Input: Consider Input: Question: When did the person who voices Itchy begin acting professionally? Passage:The Itchy & Scratchy Show (often shortened as Itchy & Scratchy) is a fictional animated television series featured in the American animated television series The Simpsons. It appears as a part of The Krusty the Clown Show. Itself an animated cartoon, The Itchy & Scratchy Show depicts a blue mouse, Itchy (voiced by Dan Castellaneta), who repeatedly kills a black cat, Scratchy (voiced by Harry Shearer). The cartoon first appeared in The Tracey Ullman Show short "The Bart Simpson Show", which aired November 20, 1988. The cartoon's first appearance in The Simpsons was in the 1990 episode "There's No Disgrace Like Home". Typically presented as 15- to 60-second-long cartoons, the show is filled with gratuitous violence that almost invariably prompts uproarious laughter from Bart and Lisa. The Simpsons also occasionally features characters who are involved with the production of The Itchy & Scratchy Show, including Roger Meyers Jr. (voiced by Alex Rocco, and, later, Hank Azaria), who runs the studio and produces the show.

Input: Consider Input: Question: How many years of professional experience did Andy Seminick have when Mack Burk pitch-ran for the catcher? Passage:Burk stood tall, weighed and threw and batted right-handed. He attended the University of Texas at Austin and signed a $40,000 bonus contract with the Phillies in September 1955. Under the rules of the day, a "bonus baby" such as Burk was compelled to spend his first two years as a professional baseball player on a Major League roster. In his pro debut, on May 25, 1956, Burk pinch-ran for catcher Andy Seminick. In his third game, on June 5, he pinch hit for pitcher Curt Simmons in the fifth inning and singled off left-hander Joe Nuxhall of the Cincinnati Redlegs. He came around to score his first big-league run that inning on a sacrifice fly by Stan Lopata. He scored two more runs during the 1956 season, both as a pinch runner. In his lone appearance in the field, Burk caught one inning, the bottom of the eighth, in relief of Lopata on July 25 against the Cardinals, and handled one chance flawlessly.

Input: Consider Input: Question: Where is the home base of the team Ted Birnie moved to during the 1906-07 Crystal Palace F.C. season? Passage:Crystal Palace started their second season in a new division, having gained promotion from the Southern League Division Two the previous season. There were a number of personnel changes this season, with Archie Grant and captain Ted Birnie moving to Chelsea and George Walker going to New Brompton. Palace's hat-trick hero in their FA Cup exploits of last season, Walter Watkins, also moved on to Northampton Town. In their places Palace brought in a number of new faces. Charles Ryan joined from Nunhead, Thomas Wills from Newcastle, Bill Forster from Sheffield United and Bill Ledger from Pryhope Villa. Wilf Innerd was made captain and played in all but one of the club's League and Cup matches. The club struggled to find their feet on the new division, and failed to score in 13 of their matches, finishing the season in 19th position, one place off the bottom. This was enough to ensure safety though, as for this season there was no relegation. Palace again called on a number of amateurs from the local area and beyond, including Henry Littlewort. Littlewort, who made his only appearance for the club this season, would go on to win a gold medal with the British Football team in the 1912 Olympics.
