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: Which of the universities was founded first, the one Howells first obtained a degree from, or the one he studied at thereafter? Passage:Howells was born on 11 May 1871 in Cwm, Monmouthshire in south Wales. He was educated at schools in Cwm and Pengam before winning a scholarship to Regent's Park Baptist College, London. After graduating with a degree awarded by the University of London, he studied at the University of Oxford (at Mansfield College and Jesus College), at Christ's College, Cambridge and at the University of Tübingen, obtaining degrees from a total of four universities. He travelled to India in 1895 for the Baptist Missionary Society to deal with literary and educational work. In 1907, he became Principal of Serampore College, a post he held until 1932. During this time, he also served as a Fellow and examiner of the University of Calcutta (1913 to 1929) and was a member of the Bengal Legislative Council in 1918. After returning to Britain in 1932, he was lecturer in Hebrew at Rawdon Baptist College until 1935. He received honorary degrees from the University of St Andrews, Serampore College and the University of Wales. During his retirement, he moved to Castleton, south Wales and he died on 7 November 1935.

Input: Consider Input: Question: Who owned the team that won the 1998 Leinster Senior Football Championship? Passage:Karl O'Dwyer was a footballer from Waterville in South Co Kerry. He played with the Kerry team that were shocked by Clare in the final of the 1992 Munster Senior Football Championship. He later played with Kildare and had much success when his father Mick was manager. In 1998 he helped Kildare to their first Leinster Senior Football Championship title since 1956, he later helped his team to a first All Ireland final since 1928 but lost out to Galway on the day. In the semi final Kildare beat O' Dwyers native Kerry. At the end of the year he picked up an All Stars Award at Full Forward. In 2000 he once again helped Kildare to a Leinster title. O'Dwyer retired from inter-county in 2002 following Kildare's defeat to Kerry in the All-Ireland Qualifiers.
