In this task, you're given a question, along with a context passage which has extra information available on certain terms mentioned in it, i.e., the proper nouns in the passage. Your job is to determine whether information from more than one term is needed to answer the question. Indicate your choice as `a` for Yes or `b` for No.

Input: Consider Input: Question: Is the political committee that Zorin held a managerial position in until 1932 still active? Passage:Zorin was born in Novocherkassk. After joining the Soviet Communist Party in 1922, Zorin held a managerial position in a Moscow City Committee and the Central Committee of the Komsomol until 1932. In 1935, he graduated from the Communist Institute of Education (Высший коммунистический институт просвещения). In 1935-1941, Zorin worked on numerous Party assignments and as a teacher. In 1941-1944, he was employed at the People's Commissariat for Foreign Affairs. In 1945-1947, Zorin was the Soviet ambassador to Czechoslovakia. In 1948, he helped organize the Czechoslovak coup d'état. In 1947-1955 and again in 1956-1965, he was Deputy Minister of Foreign Affairs of the Soviet Union. At the same time, he held other positions, including that of the permanent Soviet representative at the UN Security Council in 1952-1953. In 1955-1956, Zorin was the first Soviet ambassador to the Federal Republic of Germany. In 1956-1965, he again represented the Soviet Union at the UN Security Council, which led to his famous confrontation with Adlai Stevenson on 25 October 1962, during the Cuban Missile Crisis.

Input: Consider Input: Question: Were Caton and Beck both from Poland? Passage:From the bioelectricity of nerves, Marxow turned his attention, from 1876 on, to the global electrical activity of the cerebral hemispheres. Neuroanatomists had already determined at the time that its nervous tissue was also composed of cells (the neurons), with their bodies mainly located in the gray matter, and filamentary prolongations, the dendrites and the axons. Thus, it was only natural to assume that they would also display electrical activity. This important discovery, however, had not been made until that time, because many desynchronized electrical potentials with different polarities produce a cumulative global potential which is actually very small and difficult to detect with the sensitivity range of the measuring devices available at the time. Despite this, Marxow was able to prove for the first time that the peripheral stimulation of sensory organs, such as vision and hearing were able to provoke event-related small electrical potential swings on the surface of the cerebral cortex which was related to the projection of those senses. Strangely, however, Marxow did not publish his results, choosing instead to deposit them in a bank safe, with instructions to reveal them in 1883 only. Meanwhile, the first publications about what was later to be called the electroencephalogram came to light, independently demonstrated by Richard Caton (1842–1926), in Great Britain, and Adolf Beck (1863–1942) in Poland, both using laboratory animals.

Input: Consider Input: Question: Which of the cities Demiéville studied in after secondary school are located in Continental Europe? 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.
