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: Was Oakenfold or Rampling born first? Passage:UK disc jockeys Trevor Fung, Paul Oakenfold, and Danny Rampling are commonly credited with having "popularized" Balearic beat, specially in the UK. In 1987, after a holiday in Ibiza, Oakenfold and his friends Trevor Fung and Ian St. Paul returned to London, where they unsuccessfully tried to establish a nightclub called the Funhouse in the Balearic style. Returning to Ibiza during the summer of 1987, Oakenfold rented a villa where he hosted a number of his DJ friends, including Danny Rampling, Johnny Walker, and Nicky Holloway. Returning to London after the summer, Oakenfold reintroduced the Balearic style at a South London nightclub called the Project Club. The club initially attracted those who had visited Ibiza and who were familiar with the Balearic concept. Fueled by their use of Ecstasy and an emerging fashion style based on baggy clothes and bright colors, these Ibiza veterans were responsible for propagating the Balearic subculture within the evolving UK rave scene. In 1988, Oakenfold established a second outlet for Balearic beat, a Monday night event called Spectrum, which is credited with exposing the Balearic concept to a wider audience. It was 1988 when Balearic beat was first noticed in the U.S., according to Dance Music Report magazine. Jose Padilla, is an Ibizan DJ best known for his residency at Café del Mar. Also Jon Sa Trinxa, a british DJ and Producer best known for the longest residency on Salinas Beach at Sa Trinxa defines his style as being Balearic Music.

Input: Consider Input: Question: What languages are spoken in the city where John had a wheat farm? Passage:Chanter was born in Panoomilloo near Rochester, Victoria and was the son of John Chanter and Mary Anne Clark. His father was a farmer and politician who represented the seats of Murray and Deniliquin in the Legislative Assembly between 1885 and 1901 as a Protectionist. He held ministerial office as the Secretary of Mines in the government of George Dibbs. John Chanter, sr. was also the member for Riverina in the Australian House of Representatives at various times between 1901 and 1922. He was a member of the Protectionist Party until 1909, the Australian Labor Party and, after the Labor Party split of 1916, the Nationalist Party. John Chanter Jr. was educated at the State Primary School Moama. He established a sawmilling business in Barham and a wheat farm in Tongala. In 1927 he moved permanently to New South Wales and became a prominent wheat farmer in Lake Cargelligo. Chanter was involved in local organizations in Tongala and Lake Cargellico including the show societies, Wheatgrowers Union and Freemasons. He was elected to the position of councillor for Deakin Shire in Victoria between 1919 and 1926 and was the shire president in 1925–26. He was also elected to Lachlan Shire Council in New South Wales between 1928 and 1945 and was the president in 1940-1.
