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.

Example Input: Question: Was the Belgian Labour Party socialist? Passage:Achille Honoré Van Acker was born into a working class family in Bruges, Belgium in 1898 as the youngest of 12 children. He only attended school until the age of 11. Despite entering the workforce, Van Acker read widely and joined several social associations in Bruges. At the outbreak of World War I, he was refused by the Belgian Army because he suffered from astigmatism. While the Germans occupied most of Belgium, Van Acker fled into the small section of unoccupied territory behind the Yser Front where he worked in various menial capacities. Mixing with Belgian soldiers during the war, Van Acker became involved in socialist politics, developing a distinctive ideology based on moderate social democracy. After the end of the war, he returned to Bruges and joined the Belgian Labour Party (Belgische Werkliedenpartij, POB–BWP) and became active in socialist groups, trade unions, and cooperatives.

Example 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.

Example Input: Question: Who was the Liutenant Governor of Pennsylvania in 1930? Passage:Born on October 24, 1895, in the Lincoln neighborhood of Ephrata, Pennsylvania, Bard graduated from Millersville State Normal School (now Millersville University of Pennsylvania), then received an Artium Baccalaureus degree in 1916 from Franklin & Marshall College and a Bachelor of Laws in 1922 from the University of Pennsylvania Law School. He was a teacher in Lancaster County, Pennsylvania from 1911 to 1912. He was the principal of Warwick Township High School in Lititz, Pennsylvania from 1913 to 1915. He was the supervising principal of Ephrata schools from 1916 to 1918. He served in the United States Army from 1918 to 1919. He served as Secretary of the Democratic Committee of Lancaster County from 1920 to 1924, and served as its President from 1925 to 1934. He was in private practice in Lancaster, Pennsylvania from 1922 to 1939. In 1930, Bard was a candidate for Lieutenant Governor of Pennsylvania, and was a Pennsylvania delegate to the 1932 Democratic National Convention. He was special assistant to the Attorney General of the United States from 1934 to 1937. He was the United States Attorney for the Eastern District of Pennsylvania in 1937. He was a member of the Pennsylvania Public Utility Commission from 1937 to 1938. He was the Pennsylvania Attorney General from 1938 to 1939.
