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: Which tribe was Chief Blackfish the Chief of? Passage:Little documentary evidence of Black Hoof's life appears in the historical record before 1795. As a child he may have been a member of a waundering band of some 400 Shawnees led by Peter Chartier between 1745 and 1748, who founded the community in Kentucky called Eskippakithiki and later moved to Sylacauga, Alabama, eventually settling in Old Shawneetown, Illinois. He probably took part in the Battle of Point Pleasant during Lord Dunmore's War against the Virginia militia in 1774. During the American Revolutionary War, he may have taken part in the siege of Boonesborough in 1778, which was led by Chief Blackfish, as well as the subsequent defense of the Shawnee village of Chillicothe in 1779. In the Northwest Indian War, Black Hoof was defeated by "Mad" Anthony Wayne and, following the collapse of the Indian confederation, surrendered in 1795.

Example Input: Question: When was Kauffman Stadium built? Passage:At Kauffman Stadium, Dennis Leonard pitched a four-hit complete game to give the Royals a 21 series lead. After a one-out walk and single, Freddie Patek's RBI single off of Mike Torrez in the second put the Royas up 10. Next inning, Al Cowens's groundout with runners on second and third and no outs made it 20 Royals. The Yankees got on the board in the fifth when Graig Nettles singled with two outs and scored on Lou Pinella's double, but the Royals got that run back in the bottom of the inning when Hal McRae hit a leadoff double, moved to third on a groundout, and scored on Cowens's groundout. Next inning, Torrez allowed a leadoff walk and single, then got two outs before being relieved by Sparky Lyle, who allowed a two-run double to Amos Otis. Next inning, George Brett hit a leadoff single and scored on John Mayberry's RBI double. The Yankees got a run in the ninth when Roy White doubled with one out and scored on first baseman Mayberry's error on Reggie Jackson's ground ball before Chris Chambliss grounded out to end the game.

Example Input: Question: Which of the two men that considered the Show-Me State a lost cause was born most recently? Passage:For the better part of a century, Missouri has been reckoned as the nation's bellwether state. Prior to 2008, since 1904, Missouri had voted for the winner in every presidential election except in 1956 when the state narrowly voted for Democrat Adlai Stevenson of neighboring Illinois over incumbent Republican President Dwight D. Eisenhower. In recent years, however, it has gradually been trending Republican. Although Bill Clinton of neighboring Arkansas won the state with ease during both of his elections in 1992 and 1996, Al Gore and John Kerry considered the Show-Me State a lost cause and did not campaign much there. Although Barack Obama is from neighboring Illinois, at first he likewise put the state as a secondary concern in relation to other swing states such as Ohio and Virginia where he thought he had more of a chance. As his lead diminished in the summer months, he and McCain moved the campaign to more Democratic-friendly states, as McCain maintained a comfortable polling lead in Missouri. Similar hypothetical general match-up polls taken between McCain and Hillary Rodham Clinton, however, showed Clinton always leading in Missouri.
