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: Has the voice actor for the White Rabbit voiced any other characters? Passage:The film follows the storyline of the book closely, save for adding some scenes from Through the Looking-Glass. It also changes the opening real world scene from Alice and her sister sitting at a riverbank to Alice in her bedroom, reluctantly practicing the song "Cherry Ripe", which she is expected to perform at a garden party. (The party guests are played by the same actors as the Wonderland characters and are shown as resembling them in appearance and personality, in a similar manner to the MGM version of The Wizard of Oz. The toys in Alice's room also reflect the residents of Wonderland). Thanks to stage fright and constant nagging from her confident governess (Dilys Laye), Alice runs out of the house and hides herself in the woods nearby, planning to stay hidden until the party has ended. However, an apple floats down from the tree and seems to hover in Alice's face. She is suddenly distracted by a human-sized White Rabbit (voiced by Richard Coombs) rushing by. Curious, Alice follows the White Rabbit, falling down his rabbit hole and ending up in Wonderland.

Example Input: Question: How old was Snow Chief in the 1986 Kentucky Derby race? Passage:Solis' first rode in the Kentucky Derby in 1983 on a longshot named Current Hope, and did not place in the money. He rode the Derby again in 1986 on Snow Chief, who had won the Santa Anita Derby and was the morning line favorite, but again finished well back. The horse and rider went on to with the Preakness Stakes that year, marking Solis' only win to date in an American Triple Crown race. He was third in the 1991 Derby on Mane Minister, and also third in the Belmont Stakes on the same horse. Solis finished second in the Kentucky Derby and third in the Preakness with Captain Bodgit in 1997, second in the Derby with Victory Gallop in 1998 and second in both the Derby and the Belmont with Aptitude in 2000. His first Breeders' Cup win was the 2000 Breeders' Cup Sprint on Kona Gold. He won two Breeders' Cup races in 2003 with Johar (who finished in a dead heat) in the Breeders' Cup Turf, and the Breeders' Cup Classic on Pleasantly Perfect, both trained by Richard Mandella. He ended 2003 ranked fourth nationally in purse earnings with a career-best $16,304,252.

Example Input: Question: What type of school is the King's School in Canterbury? Passage:The ruins of the Norman Canterbury Castle and St Augustine's Abbey are both open to the public. The medieval St Margaret's Church now houses "The Canterbury Tales", in which life-sized character models reconstruct Geoffrey Chaucer's stories. The Westgate is now a museum relating to its history as a jail. The medieval church of St Alphege became redundant in 1982 but had a new lease of life as the Canterbury Urban Studies Centre, later renamed the Canterbury Environment Centre; the building is used by the King's School. The Old Synagogue, now the King's School Music Room, is one of only two Egyptian Revival synagogues still standing. The city centre contains many timber-framed 16th and 17th century houses, however there are far fewer than there were before the Second World War, as many were damaged during the Baedeker Blitz. Many are still standing, including the "Old Weaver's House" used by the Huguenots. St Martin's Mill is the only surviving mill out of the six known to have stood in Canterbury. It was built in 1817 and worked until 1890; it is now a house conversion. St Thomas of Canterbury Church is the only Roman Catholic church in the city and contains relics of Thomas Becket.
