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 did Luigi Chinetti drive in the race? Passage:Sommer was born in Mouzon, in the Ardennes departement of France, into a wealthy Sedan carpet-making family. His father, Roger Sommer, broke the Wright Brothers' record for the longest flight in 1909. It was not until 1931 that Raymond started to display daredevil tendencies of his own, entering motor races in a privateer Chrysler Imperial. The following year, he won the 24 Hours of Le Mans race, despite having to drive over 20 hours solo after his teammate, Luigi Chinetti, retired ill. During the 1930s, Sommer was to dominate the French endurance classic, winning again in 1933 driving an Alfa Romeo alongside Tazio Nuvolari. He also led every race until 1938, only to suffer a mechanical failure, once when 12 laps in the lead. Sommer traveled to Long Island, New York, to compete in the 1936 Vanderbilt Cup where he finished fourth behind the winner, Nuvolari.

Example Input: Question: What was the age difference between the commodore and his brother? Passage:Samuel Shaw was a Revolutionary War naval officer who, along with Richard Marven, were the first whistleblowers of the infant United States. As a whistleblower, Shaw was instrumental in the Continental Congress' passage of the first whistleblower protection law in the United States. Shaw, a midshipman, and Marven, a third lieutenant in the Continental Navy, were moved to act after witnessing the torture of British prisoners of war by Commodore Esek Hopkins, then Commander-in-Chief of the Continental Navy. Shaw and Marven were both from Rhode Island, as was Hopkins, whose brother was Stephen Hopkins, Governor of the new state, and a signatory to the Declaration of Independence. For reporting the misconduct of the Navy's highest officer, Shaw and Marven were both dismissed from the Navy. Worse still, Hopkins then filed a criminal libel suit against Shaw and Marven in the Rhode Island Courts.

At the university he was known for scholarship; John Fell employed him in 1672 on an edition of Florus. He also worked on Edmund Chilmead's edition of the chronicle of John Malalas.
