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 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 years did the war last where the castle was strengthened in the middle of it? Passage:In 1575, in the middle of the Wars of Religion, the castle was strengthened. It was nevertheless besieged and taken by the Geuzen, locally known as the Hurlus in 1579, before being taken back three months later. In 1627, Philip IV of Spain promoted the seigneury to the rank of county. The Franco-Dutch War under Louis XIV devastated this mostly agricultural region. Mouscron and the surrounding area became French after the Treaty of Aix-la-Chapelle (1668). Part of it rejoined the Southern Netherlands after the Treaty of Nijmegen (1678), which drew the frontier right through its territory. It was finally completely ceded to the Southern Netherlands under the terms of the Treaty of Utrecht in 1713. The textile industry started in Mouscron in the 1760s thanks to the imposition by Lille of a ban on the fabrication of molletons, a mixture of flax and wool, in Roubaix and Tourcoing. With the Battle of Fleurus (1794), Mouscron went back to France.

Example Input: Question: When was the university that Scott went to at age 19 founded? Passage:Scott was born in Cooksville, Illinois near the town of Normal, Illinois. He lived on a farm until the age of 19 when he entered Illinois State Normal University. He remained at the university for two and a half years while teaching at country schools. With the aid of scholarship, he was able to attend Northwestern University in 1891 where he received a Bachelor of Arts degree in 1895. He desired to become a university president in China, so he enrolled at McCormick Theological Seminary; however, upon his graduation in 1898, he could not find a position. Instead, he decided to go to Germany with his wife and study psychology with Wilhelm Wundt at the University of Leipzig. While there, he received his Doctorate of Philosophy in psychology and education in 1900.
