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 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 earned the bronze medal in the event where the Austrian athlete earned the gold? Passage:Sonja Henie of Norway won her third straight gold medal in the ladies' singles figure skating event, her last Olympic medal as she turned professional shortly after the Games.

Norway's Ivar Ballangrud was the most successful athlete, winning three golds and a silver in speed skating and taking his career total to seven Olympic medals.

Example Input: Question: What is the name of the Young Pretender? Passage:Inside the church are galleries on the north, west, and south sides. These are carried on Tuscan columns, which rise to the ceiling as wooden quasi-Tuscan columns. At the east end of the church are paintings by Jacob Thompson of Penrith dated 1845 depicting the Angel and the Shepherds, and the Agony in the Garden. The communion table dates from 1722, and was lengthened in 1951. The brass chandeliers were given to the church in 1746 by the 2nd Duke of Portland in recognition of the part the town played in the defence against the Young Pretender in 1745. The pulpit consists of the top section of a former three—decker. At the back of the gallery are royal arms dated 1723 by Mathias Read. The font consists of a simple octagonal bowl, and is dated 1661 which is the date it was brought back into use after the Restoration of King Charles II. The stained glass in the east window of 1870 is by Hardman, and that in the north aisle, dating from 1889, is by Burlison and Grylls. Elsewhere are windows by Clayton and Bell, Powell's, G.J.Baguley, and by Cox, Sons and Buckley. The monuments include two coffin lids inscribed with foliated crosses, one dating from the 14th century, the other possibly from the 12th century. There are also two worn stone effigies from the 17th century.
