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 times did the Wisconsin Progressive Party win the governor of Wisconsin? Passage:Wiley was the Republican candidate for governor of Wisconsin in 1936, but his bid failed. Philip La Follette and the new Wisconsin Progressive Party, which split from the Republicans in 1934, won the election. In 1938, Wiley was elected to the U.S. Senate by defeating incumbent F. Ryan Duffy. In 1944, he was challenged by United States Marine Corps Captain Joseph R. McCarthy in the Republican primary. He defeated McCarthy and won the general election. Wiley, then an isolationist in foreign policy, and Governor Walter S. Goodland supported Republican presidential nominee Thomas E. Dewey in the 1944 race over incumbent Franklin D. Roosevelt, and Dewey won Wisconsin's electoral votes but fell far short nationally.

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: Where was the author that Whittier College was named for born? Passage:Named after Whittier College in Whittier, California, the ship was built at the California Shipbuilding Yard (Calship) in Los Angeles, California in just 82 days and was delivered on 18 July 1945. The Whittier City and Whittier College was named for author John Greenleaf Whittier. SS Whittier Victory was the 798 of the 10,500-ton class known as Victory ships, built under the Emergency Shipbuilding program. Victory ships were designed to replace the earlier Liberty ships. Liberty ships were designed to be used solely for World WarII. Victory ships were designed to last longer and serve the US Navy after the war. The Victory ship differed from a Liberty ship in that it was faster, longer, wider, taller, and had a thinner stack set farther toward the superstructure and a long raised forecastle. She was a United States Merchant Marine ship operated by the Moore-McCormack Lines for World war 2. She loaded up cargo at a few west coast ports and streamed to support the Pacific War. SS Whittier Victory delivered supplies in the island-hopping campaigns towards the Empire of Japan. As a Merchant Marine ship, she had a civilian crew to man the ship and US Navy Armed Guards to man the deck guns.
