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: How many years had Tortola been a British colony when Smith was born? Passage:Ethlyn Eugenie Smith was born on 23 April 1940 in the village of Huntums Ghut, on the island of Tortola, at the time a British colony known as the British Leeward Islands to Gladys and Ernest Smith. She completed her primary and secondary education in the islands and worked briefly as a clerical trainee in the civil service of the island. To further her education, she pursued an associates degree from the College of the Virgin Islands in Charlotte Amalie, in the U. S. Virgin Islands. She completed her degree program in accounting in 1968 and went on for further studies at Wandsworth Technical College in London and at the University of Calgary.

Question: How many total people have been awarded the fellowship that Heutz received in 2007? Passage:Heutz joined Imperial College London in 2007 as a Royal Society Dorothy Hodgkin Research Fellow. She was awarded the 2008 Institute of Materials, Minerals and Mining Silver Medal for her research on organic thin films. In particular she had developed new electron - donor morphologies for efficient solar cells. Heutz specialises in the use of electron paramagnetic resonance (EPR) to monitor unpaired electrons within materials. She used EPR to monitor spins within copper phthalocyanine solar cells. Whilst working on new materials for photovoltaics, Heutz showed that electrons in copper phthalocyanine (a blue pigment found in a Bank of England £5 note) exist in a superposition of two different spin states. She demonstrated that copper phthalocyanine could be used for quantum computing, where information is stored as qubits as opposed to binary bits.

Question: What was the population of Paris the year Zambezi Sun debuted at Longchamp Racecourse? Passage:Trained by Pascal Bary, Zambezi Sun made his debut at the beginning of April 2007 at Longchamp Racecourse in Paris, winning the Prix Juigne, an event for unraced three-year-old colts and geldings. In his next start on April 29, he won the Prix de Nanterre at the Longchamp course and then on June 3 at Chantilly Racecourse he ran fourth to winner Lawman in the Group 1 Prix du Jockey Club. Back at Longchamp Racecourse, Zambezi Sun rebounded to win the prestigious G-1 Grand Prix de Paris. He did not race again until mid September when he ran third to Soldier of Fortune in the Prix Niel. In October he finished eighth in France's most prestigious race, the Prix de l'Arc de Triomphe. In contention during the final stretch run, eventual winner Dylan Thomas cut sharply in front of Zambezi Sun, but a claim of interference was rejected by the racing stewards.
