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 the Beach Boys released "Don't Worry Baby" did Roger Christian pass away? Passage:During a vocal tracking session in which Manson was singing over music already written for "Push It", the band felt that one of the lines in "Push It" would benefit from having a vocal chorus answering the words back to her. Inspired by Manson's spontaneous ad-lib of the phrase "don't worry baby" over the music, guitarist Steve Marker sampled the Beach Boys song "Don't Worry Baby" and used it as a backing vocal. The sample didn't work with what the band had already recorded so Manson re-sang the lines to fit the key and tempo of the song. Aware of the potential for incurring copyright legalities, the band debated whether or not to keep the line. Garbage and Brian Wilson coincidentally shared the same publishing company (Irving Music), and figuring that they had nothing to lose, contacted him through their company representative, sent him a copy of "Push It", and asked him for permission to use the interpolation. Wilson gave his blessing, and reportedly kept the tape. Both Wilson and Roger Christian, the deceased co-writer of "Don't Worry Baby", received a writing credit. A simpler interpolation credit was given to Herbie Azor, as the band's lawyers felt that there was a possible similarity of the line "Push it!" to his own "Push It", which had been a hit single for New York hip hop trio Salt-N-Pepa.

Example 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.

Example Input: Question: In which country was Sir Anthony Hoskins a naval officer? Passage:Admiral Sir Anthony Hiley Hoskins, (1 September 1828 – 21 June 1901) was a Royal Navy officer. As a junior officer, he took part in the Cape Frontier War of 1851 and then saw action at the Battle of Canton in December 1857 and the Battle of Taku Forts in May 1858 during Second Opium War. Once promoted to flag officer rank, he acted as Second-in-Command of the Fleet at the bombardment of Alexandria in July 1882 during the Anglo-Egyptian War. He went on to be First Naval Lord in September 1891 but in that role took a relaxed view of the size of the Fleet and did not see the need for a large shipbuilding effort on the scale envisaged by some of his colleagues, such as Admiral Sir Frederick Richards and Admiral Sir John Fisher who were concerned about French and German naval expansion.
