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: 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: What Texas county was Irving Loeb Goldberg born in? Passage:Born in Port Arthur, Texas, Goldberg received a Bachelor of Arts degree from the University of Texas at Austin in 1926 and a Bachelor of Laws from Harvard Law School in 1929. He was in private practice in Beamont, Texas in 1929, in Houston, Texas in 1930, and in Taylor, Texas in 1931. He was an in-house counsel at The Murray Company in Dallas, Texas from 1932 to 1934, returning to private practice in Dallas from 1934 to 1942. He was a United States Naval Reserve Lieutenant during World War II from 1942 to 1946. He was thereafter again in private practice in Dallas until 1966, becoming lead name partner at Goldberg, Fonville, Gump & Strauss (now Akin Gump Strauss Hauer & Feld).

Input: Consider Input: Question: Who owns the paper that Fago sold his first cartoon to? Passage:Fago was born in 1914 in Yonkers, New York, of parents who had immigrated from Naples, Italy. He had two sisters and a 10-year-older brother, Al Fago. At 14, Vincent Fago sold his first cartoon to the New York Sun, for $2. He attended DeWitt Clinton High School in the Bronx, graduating at age 20, he recalled in 2001, after encountering difficulties upon losing vision in one eye at age 16. By this time he had begun work as an animation tracer at Audio Productions in the old Edison studios in The Bronx, and advanced to become an in-betweener after the company moved to the Fox Movietone News Building. He then worked four years at the Jam Handy Studio in Detroit, Michigan, contributing, he said, to "films for Chevrolet, and stop-motion pictures, and Technicolor films for the Metropolitan Life Insurance Company. From there, he spent four years in Florida as an animator at Fleischer Brothers Studios, where he worked as an assistant animator on Betty Boop, Popeye and Supermantheatrical shorts and on the animated features Mr. Bug Goes to Town and Gulliver's Travels.
