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.

Input: Consider Input: 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.

Input: Consider Input: Question: Is the university of Paris in France? Passage:Following his completion of secondary school, Demiéville spent time studying in Munich, London, and Edinburgh, where he was able to attend lectures by George Saintsbury at the University of Edinburgh. He then attended the University of Paris, where he wrote an essay on the musical suite of the 17th and 18th centuries and was awarded a licentiate degree in 1914. Demiéville then spent the year 1915 studying at King's College London where he was introduced to Chinese, which quickly became his focus. After returning to France, Demiéville studied at the École des Langues Orientales Vivantes (School of Living Oriental Languages), after which he moved to the Collège de France, where he further studied Chinese under the tutelage of Édouard Chavannes and began learning Sanskrit from Sylvain Lévi. He earned his Diplômé from the École des Langues Orientales Vivantes in 1919.

Input: Consider Input: Question: How long did the Battle of the Paracel Island last for? Passage:USS Castle Rock (AVP-35) was a United States Navy Barnegat-class small seaplane tender in commission from 1944 to 1946 which saw service in the late months of World War II. After the war, she was in commission in the United States Coast Guard as the Coast Guard cutter USCGC Castle Rock (WAVP-383), later WHEC-383, from 1948 to 1971, seeing service in the Vietnam War during her Coast Guard career. Transferred to South Vietnam in 1971, she served in the Republic of Vietnam Navy as the frigate RVNS Trần Bình Trọng (HQ-05) and fought in the Battle of the Paracel Islands in 1974. When South Vietnam collapsed at the end of the Vietnam War in 1975, Trần Bình Trọng fled to the Philippines, where she served in the Philippine Navy from 1979 to 1985 as the frigate RPS (later BRP) Francisco Dagohoy (PF-10).
