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.

[Q]: 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.

[Q]: Question: How long did Andrew Allen serve as the Attorney General of Pennsylvania? Passage:Allen was born into a prominent Philadelphia family. His father, William Allen, was a successful merchant and lawyer, and would later be the Chief Justice of the Supreme Court of Pennsylvania. Andrew graduated from the City College of Philadelphia (later the University of Pennsylvania) in 1759, read law under Benjamin Chew, and then went to London to complete a legal education at the Inner Temple. He returned to Philadelphia in 1765, was admitted to the bar, and began to practice law. That same year Allen was elected to the Pennsylvania Assembly. In 1766, he was appointed the colony's Attorney General. He married Sarah ("Sally") Coxe, sister of Tench Coxe, in April 1768. In 1770 his brother-in-law, Governor John Penn, gave him a seat on the Governor's Council.

[Q]: Question: Why did Johnathon Wilson leave the band that Garron DuPree replaced him in? Passage:Garron DuPree joined the group Eisley in 2005 at the age of 15, following the departure of their former bassist Jonathan Wilson. He is the cousin of the group's remaining members Chauntelle DuPree, Stacy DuPree, Weston DuPree, and Sherri DuPree. At the time of Garron's arrival with the Texas-based indie-pop band, they were entering a phase of heavy touring in support of their debut album Room Noises. Garron toured as Eisley's bassist beginning with the group's 2005 Yahoo sponsored "Who's Next?" tour, followed closely by 2005's Austin City Limits festival and closing out the year with Switchfoot's Nothing Is Sound tour. Eisley continued touring throughout 2006, visiting Australia in support of Taking Back Sunday, touring the United States with supporting band Dawes for their first major headlining tour, as well as touring Europe. Garron's bass work with Eisley began on their second full-length record, Combinations, and has remained the sole bassist on the remainder of Eisley's recordings to date. In 2013, Garron expanded his repertoire when he joined Say Anything as their bassist, replacing touring bassist Adam Siska. His bass work has been said to be inspired by Radiohead, Kent, Pink Floyd, the Beatles, and Matt Rubano, among others.
