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 is the maximum length of the species that is known to prey on the crossback stingaree? Passage:The broadnose sevengill shark (Notorynchus cepedianus) is known to prey on the crossback stingaree. When threatened, this ray raises its tail warningly above its body in a scorpion-like fashion. Parasites documented from this species include a tapeworm in the genus Acanthobothrium, and the monogenean Calicotyle urolophi. Like other stingrays, the crossback stingaree is aplacental viviparous: when the developing embryos exhaust their supply of yolk, their mother provisions them with nutrient-rich histotroph ("uterine milk") through specialized extensions of the uterine epithelium called "trophonemata". Females produce litters of 1–4 pups every other year. Embryonic development proceeds rapidly over a six-month period, though the total gestation period may be much longer if there is a period of dormancy for the eggs after fertilization, as has been reported in other stingarees. Off Tasmania, large estuaries such as at the mouth of the River Derwent serve as nursery areas.

Example Input: Question: When did the person die who had a long feud with FDR? Passage:Roosevelt came to office in 1929 as a reform Democrat, but with no overall plan. He tackled official corruption by dismissing Smith's cronies and renamed the New York Public Service Commission. He addressed New York's growing need for power through the development of hydroelectricity on the St. Lawrence River. He reformed the state's prison administration and built a new state prison at Attica. He had a long feud with Robert Moses, the state's most powerful public servant, whom he removed as Secretary of State but kept on as Parks Commissioner and head of urban planning. Moses was replaced with the Bronx's Democratic Boss Edward J. Flynn. When the Wall Street crash in October 1929 ushered in the Great Depression, Roosevelt started a relief system that later became the model for the New Deal's Federal Emergency Relief Administration (FERA). Roosevelt followed President Herbert Hoover's advice and asked the state legislature for $20 million in relief funds, which he spent mainly on public works in the hope of stimulating demand and providing employment. Aid to the unemployed, he said, "must be extended by Government, not as a matter of charity, but as a matter of social duty." In his first term, Roosevelt famously said, "The United States Constitution has proved itself the most marvelously elastic compilation of rules of government ever written." He was referring to the belief he had that the Federal government would need to use more power in order to bring the country out of the Depression.

Example Input: Question: What position did Richard Seymour play on the Patriots? Passage:Battling the Dolphins for the division lead, the Patriots erased a 13–6 gap with a Brady touchdown pass to David Givens in the third. The Dolphins marched down field late in the fourth; during this drive a Ricky Williams first down run was protested by the Patriots who felt Williams' knee touched the dirt infield at Pro Player Stadium, but the challenge was denied. The Dolphins attempted a 35-yard field goal at the two-minute warning, but the kick was blocked by Richard Seymour. The Dolphins smothered the Patriots' final drive attempt (the decisive play came when former Patriot Terrell Buckley stopped Kevin Faulk for a four-yard loss and the game went to overtime. Controversy ensued on the coin flip for overtime; referee Gerald Austin used a silver dollar; the coin came up Lady Columbia (which is "heads" on a silver dollar) but Patriot captains Brady and Seymour protested that it came up "tails." The Dolphins drove downfield but missed another 35-yard field goal try, in part because Olindo Mare couldn't plant his foot on the infield dirt, which was still in place because of the Florida Marlins' run towards their 2003 World Series victory; after forcing a Patriots punt Jay Fiedler was hit by Tedy Bruschi and lobbed a 60-yard pass picked off at the Patriots 18-yard line by Tyrone Poole. Brady then ended the game with a spectacular 82-yard touchdown strike to Troy Brown and a 19–13 final.
