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: When did the person die who had a long feud with FDR? Passage:Roosevelt came to office in 1929 as a reform Democrat, but with no overall plan. He tackled official corruption by dismissing Smith's cronies and renamed the New York Public Service Commission. He addressed New York's growing need for power through the development of hydroelectricity on the St. Lawrence River. He reformed the state's prison administration and built a new state prison at Attica. He had a long feud with Robert Moses, the state's most powerful public servant, whom he removed as Secretary of State but kept on as Parks Commissioner and head of urban planning. Moses was replaced with the Bronx's Democratic Boss Edward J. Flynn. When the Wall Street crash in October 1929 ushered in the Great Depression, Roosevelt started a relief system that later became the model for the New Deal's Federal Emergency Relief Administration (FERA). Roosevelt followed President Herbert Hoover's advice and asked the state legislature for $20 million in relief funds, which he spent mainly on public works in the hope of stimulating demand and providing employment. Aid to the unemployed, he said, "must be extended by Government, not as a matter of charity, but as a matter of social duty." In his first term, Roosevelt famously said, "The United States Constitution has proved itself the most marvelously elastic compilation of rules of government ever written." He was referring to the belief he had that the Federal government would need to use more power in order to bring the country out of the Depression.

Example Input: Question: Which of the companies involved with the three-dimensional integrated circuit was founded first? Passage:In 1986, Mitsubishi Electric researchers Yoichi Akasaka and Tadashi Nishimura laid out the basic concepts and proposed technologies for 3D ICs. The following year, a Mitsubishi research team including Nishimura, Akasaka and Osaka University graduate Yasuo Inoue fabricated an image signal processor (ISP) on a 3D IC, with an array of photosensors, CMOS A-to-D converters, arithmetic logic units (ALU) and shift registers arranged in a three-layer structure. In 1989, an NEC research team led by Yoshihiro Hayashi fabricated a 3D IC with a four-layer structure using laser beam crystallisation. In 1990, a Matsushita research team including K. Yamazaki, Y. Itoh and A. Wada fabricated a parallel image signal processor on a four-layer 3D IC, with SOI (silicon-on-insulator) layers formed by laser recrystallization, and the four layers consisting of an optical sensor, level detector, memory and ALU.

Example Input: Question: How many soldiers were there in the Russian Imperial Army? Passage:He returned to the factory in Kamianske during the Russian Revolution of 1905. He again joined the volunteer fire brigade. He returned to Vilnius in 1911 and organized a fire brigade in Šnipiškės in 1914. Semashko rallied the men into a militia to protect the city from hooligans and fires when the Russian Imperial Army abandoned the city during the Great Retreat in mid 1915. He became city's fire chief (brandmajor) and commanded both local and German Ober Ost firefighters during fire. At the same time, he turned away from Polish political activists towards Belarusian and Lithuanian causes. He was a contributor to the Belarusian newspaper Homan and was elected to the Rada of the Belarusian Democratic Republic in January 1918. He participated in the declaration of independence of the Belarusian People's Republic and drafted plans for establishing a Belarusian university, named after Adam Mickiewicz, in Minsk. On 23 April 1918, he participated in discussions with the Council of Lithuania regarding the territory of Lithuania and Belarus after the war and ideas on resurrecting the old Grand Duchy of Lithuania.
