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: What was the founding date of the team Foster played against in the 2001 FA Trophy final? Passage:After a short period in Scotland, Foster returned to English football with Doncaster Rovers where his opportunities were limited, though he had a spell with Ilkeston Town on loan. In 2001, he signed for Forest Green Rovers in the Conference National. He made well over 100 appearances for the club and had a spell as captain. He also appeared for Forest Green in the 2001 FA Trophy final at Villa Park but was on the losing side in a 1-0 defeat to Canvey Island. He was highly regarded amongst the supporters at The Lawn and many were sad to see him leave when he departed for Halifax Town in 2004. He made just under 100 league appearances for Halifax at The Shay before a move in 2007 to Oxford United.

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: Who signed the Treaty of Sevres? Passage:The intention declared in the royal speech at the opening of the Chamber of resuming the war against Kemal was supported by an official report issued on January 10 of a renewal of the Greek offensive to the northeast of Smyrna and in the Brussa area, and the same day the Greeks occupied Belejik. On the following day the Greek Liberal organ Patris published a letter from Nice, where Venizelos was residing at the time, confirming the Greek statesman's final decision to retire from politics. This decision was naturally not displeasing to the supporters of King Constantine, who a little later found another cause for jubilation when the king of Italy received the newly appointed Greek minister to Rome (January 13). Thus Italy was the first among foreign Allied and neutral powers to recognize King Constantine. But the enthusiasm was soon damped by the joint representations made on the 20th to the Greek government by the British and French ministers in Athens on the transformation of the Chamber into a National Assembly. This action by the two Allied governments was declared to be based on the rights of the powers in question as guarantors of the constitution of Greece, rights which they considered as still existent, since the Treaty of Sèvres, in which they were surrendered, had not yet been ratified by all the signatories. Early in February the Allied Supreme Council invited the Greek and Turkish governments to attend a conference to be held in the latter part of the month in London with the object of bringing about peace between the two countries. The invitation was coldly received in Athens, and was the cause of a split in the Dimitrios Rallis cabinet on the score of wounded personal vanities. Dimitrios Gounaris, minister of war, the real leader of the Constantino faction, who, in deference to Allied public opinion, which had stigmatized him as a pro-German, had after the defeat of the Venizelists been compelled to renounce his claims to the premiership in favor of the less compromised Rallis, after being also refused the presidency of the Greek delegation to the London conference, resigned, bringing about a ministerial crisis.
