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 many times was the ATCA used in 2001? Passage:In 2001 Sinaltrainal v. Coca-Cola was filed in the Florida Third District Court of Appeal, demanding a monetary compensation for $500 million for the deaths of three workers, members of the National Union for Food Industry Workers who worked in the Coca-Cola Bebidas y Alimentos plant in Carepa in northern Colombia. The lawsuit was brought by the Colombian trade union Sinaltrainal (National Union of Food Workers) and alleged that Panamco, a Colombian Coca-Cola bottling company, assisted paramilitaries in murdering several union members. Even though the alleged human rights violation occurred in Colombia, the union attempted to use the Alien Tort Claims Act (ATCA) to bring the case into a U.S. district court. The ATCA grants U.S. courts jurisdiction in any dispute where it is alleged that a tort has been committed in violation of the "law of nations" or a treaty of the United States. The plaintiffs also alleged violations of the Torture Victims Protection Act (TVPA).

Example Input: Question: Which French naval officer who commanded raids from Isle de France against British merchant ships joined the French navy first? Passage:During the Napoleonic wars, Île de France became a base from which the French navy, including squadrons under Rear Admiral Linois or Commodore Jacques Hamelin, and corsairs such as Robert Surcouf, organised raids on British merchant ships. The raids (see Battle of Pulo Aura and Mauritius campaign of 1809–1811) continued until 1810 when the British sent a strong expedition to capture the island. The first British attempt, in August 1810, to attack Grand Port resulted in a French victory, one celebrated on the Arc de Triomphe in Paris. A subsequent and much larger attack launched in December of the same year from Rodrigues, which had been captured a year earlier, was successful. The British landed in large numbers in the north of the island and rapidly overpowered the French, who capitulated (see Invasion of Isle de France). In the Treaty of Paris (1814), the French ceded Île de France together with its territories including Rodrigues and Seychelles to Great Britain. The island then reverted to its former name, 'Mauritius'.

Example Input: Question: How many people were employed by NASA the year Kepler was launched? Passage:The Kepler spacecraft is a NASA telescope equipped with photometric equipment. Launched in 2009, Kepler continuously watches 156,000 stars in a small area. A team of astronomers, hoping to learn more about hot jupiter planets and brown dwarfs, selected four F-type stars from the Kepler Input Catalog flagged as host to a Kepler Object of Interest (a transiting object that could possibly be a planet). Using three quarters of Kepler's data, the science team conducted a follow-up investigation in using the SOPHIE échelle spectrograph at the Haute-Provence Observatory in southern France, observing stars Kepler-40, Kepler-39, KOI-552 and KOI-410. Of these, conclusive evidence of a planet orbiting KOI-410 could not be found, and KOI-552 was found to be a binary star with an M-type companion. The Hot Jupiter KOI-428b was the first of these four to be confirmed.
