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.

Question: What is the latitude and longitude of the town where Grandage was born? Passage:Grandage was born in Yorkshire, England, and raised in Penzance, Cornwall, where his parents ran a family business. He was educated at the Humphry Davy Grammar School before training as an actor at the Royal Central School of Speech & Drama through 1984. He spent twelve years working as an actor for companies such as the Royal Exchange and the Royal Shakespeare Company and was also a member of National Youth Theatre before turning to directing. He made his directorial debut in 1996 with a production of Arthur Miller's The Last Yankee at the Mercury Theatre, Colchester. In 1998 he was invited by Sheffield Theatres to direct Twelfth Night, his first Shakespeare production. In the same year he made his London directorial debut at the Almeida Theatre with a production of Shaw's The Doctor's Dilemma.

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'.

Question: What is the current enrollment of the school where Cissé studied physics?  Passage:Cissé was born in Niamey, Niger. As a child he assumed that he would work in his father's law firm. He became interested in science through Hollywood films. In Niamey there were few opportunities to practise science as his school did not have a laboratory. He was keen to move to America to study, and completed high school two years early. He moved to the United States at the age of 17 to attend college. Cissé studied physics at the North Carolina Central University and graduated in 2004. During his undergraduate degree he was encouraged by Carl Wieman to apply for a fellowship, and spent a summer at Princeton University working in condensed matter physics. During this summer project he looked at jammed disordered packings, investigating how M&M's arrange in a small volume with Paul Chaikin. Cissé used various techniques to study jammed packings, including magnetic resonance imaging, but in the end used a much simpler approach - painting M&M's and analysing how many times they knocked into each other. The result was published in Science. He moved to Urbana for his graduate studies, and earned his PhD under the supervision of single molecule biophysicist Taekjip Ha at the University of Illinois at Urbana–Champaign in 2009. After completing his doctorate, Cissé joined the École Normale Supérieure in Paris. He worked as a Pierre Gilles de Gennes Fellow in the joint labs of a physicist, Maxime Dahan, and a biologist, Xavier Darzacq. He also held a long-term fellowship with the European Molecular Biology Organization. In Paris, Cissé developed the single-cell microscopy technique time-correlated photoactivated localization microscopy (tcPALM), allowing for time resolved measurements in vitro. Cissé used transient-PALM to demonstrated that RNA polymerase II forms clusters that deconstruct after their work is done. Until Cissé made this discovery it was assumed that RNA polymerases were stable.
