In this task, you're given a question, along with a context passage. The passage will not have a direct answer to the question, but can include some information and a clue for the answer. Assuming you can only obtain information about one entity in the passage, your job is to determine whether information from the passage can be used to answer the question. Indicate your choice as `a` for Yes or `b` for No.

Example Input: Question: How long was the person that Shields succeeded in 1911 Captain the the team? Passage:Shields played first for Leicestershire in 1906 and became a regular player as wicketkeeper in 1907, thereafter playing fairly regularly until the end of the 1910 season. He succeeded Sir Arthur Hazlerigg as captain for the 1911 season with an extremely poor side: Vivian Crawford, a mainstay of the batting, had departed for Sri Lanka and fast bowler Thomas Jayes was able to play only two matches because of the tuberculosis that led to his early death; in addition, Ewart Astill, the other reliable bowler of previous years, lost form so badly that he lost his place in the team. Wisden Cricketers' Almanack noted that "no one but a sanguine man of happy disposition could have gone through the season at all complacently". In 24 first-class matches, Leicestershire lost 18 times and gained just a single victory, though they did not finish bottom of the County Championship because Somerset's record was even worse. The single victory was one of the sensational matches of the season: Yorkshire, in the match after Wilfred Rhodes' benefit match, were shot out for just 47 by John King's left-arm medium pace and Leicestershire won by an innings.

Example Input: Question: Is serpentine blue like Boron? Passage:The earliest recorded blue diamond, the Hope Diamond, was discovered in India, in the Kollur mine in the Guntur district of Andhra Pradesh (which at the time was part of the Golconda kingdom), in the seventeenth century. However, blue diamonds have also been discovered in the Cullinan Mine in South Africa and the Golconda region. A few blue diamonds have been discovered in the Argyle Mine in Western Australia as well, and are offered at their annual Argyle Tender when they are found. It is thought that blue diamonds, unlike most other diamonds, are formed in the lower part of Earth’s mantle, and that the boron creating their blue color originates from serpentinite carried down to the mantle by subducting ocean tectonic plates.

Example Output: b

Example Input: Question: Between Young's 1969 album and his 1970 album, which sold more copies? Passage:Members of this band had already released an album in 1968 as The Rockets, and had appeared on record twice with Neil Young as Crazy Horse. The core trio from the Rockets, Danny Whitten, Billy Talbot, and Ralph Molina, provided instrumental backing for Young's 1969 album Everybody Knows This Is Nowhere, and performed on some songs from Young's 1970 album After the Gold Rush. Producer/keyboardist Jack Nitzsche, who had been a member of Phil Spector's Wrecking Crew and played on records by The Rolling Stones, had worked with Young on his debut album and on tracks for Buffalo Springfield. He was drafted into Crazy Horse to back up Young on their short tour in early 1970. During sessions for Gold Rush, they met teenage guitar prodigy Nils Lofgren, who joined the band in time for this album, picking up a contract with Reprise Records after the exposure garnered from their association with Young.
