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 many other operas did the composers of Patience write? Passage:In September 2005, Ball made his New York City Opera debut as Reginald Bunthorne in Gilbert and Sullivan's Patience. He spent the first quarter of 2006 on complete vocal rest, following the illness that caused him to leave The Woman in White on Broadway. By the middle of July, Ball had taken part in the Royal Court Theatre's celebratory performance of The Rocky Horror Show. He took a leading role in Kismet in June and July 2007 for the ENO, and appeared on Channel 4's Richard & Judy on 22 June 2007 to promote this production. He then appeared as the solo artist in a controversial 'Musical Theatre' Prom on 27 August 2007 for the BBC at London's Royal Albert Hall. Ball performed a wide range of musical theatre numbers, including several by Andrew Lloyd Webber. The show was broadcast live on BBC Four, as well as on BBC Radio 3.

Q: Question: Who was in charge of running the Interdenominational Theological Center when Moss Jr. completed his graduate coursework there? Passage:Moss was born in and raised in LaGrange, Georgia, the fourth of five children. After being orphaned at 16 he earned his B.A. at Morehouse College in 1956, before earning his Master of Divinity from the Morehouse School of Religion in 1959. At Morehouse Moss was taught and mentored by Benjamin Mays, who was also a mentor to Martin Luther King Jr. While at Morehouse Moss helped lead sit-ins and other activities to protest segregation. He completed further graduate coursework at the Interdenominational Theological Center from 1960 to 1961. He also earned a Doctor of Ministry from United Theological Seminary in 1990, where he was taught by Samuel DeWitt Proctor and became friends with Jeremiah Wright, pastor of the famous Trinity United Church of Christ in Chicago and pastor of Barack Obama. Moss's son, Otis Moss III, would later take over as senior pastor for Wright after he was caught up in a controversy during the 2008 presidential election over the content of sermons he gave during the time in which Barack Obama attended the church.
