Question: In which state did Don Cardwell no-hit the St. Louis Cardinals 4-0 in the second game of a doubleheader? Passage:Cardwell was traded to the Cubs on May 13, 1960, for Tony Taylor. Two days later, he no-hit the St. Louis Cardinals 40 in the second game of a doubleheader at Wrigley Fieldthe first no-hitter ever thrown by a pitcher in his first start with a new team. The lone baserunner for the Cardinals was by a walk from Cardwell to Alex Grammas with one out in the first inning; Cardwell then retired the next 26 batters. Two ninth-inning catches enabled Cardwell to secure the no-hitter: the first catch by Cubs right fielder George Altman on a Carl Sawatski line drive for the first out of the inning, and the second catch by Cubs left fielder Walt "Moose" Moryn on Joe Cunningham's sinking line drive to end the game, Moryn catching the ball just inches off the ground. Cardwell finished the season 916 and the Cubs 6094 despite his no-hitter. Cardwell also showed his hitting ability in 1960, getting 16 hits including five home runs in 77 at bats for a .208 batting average.

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 (18421926), in Great Britain, and Adolf Beck (18631942) in Poland, both using laboratory animals.

Question: Who was the ruler of the country where Cretin was born? Passage:He was born in Montluel, in the departement of Ain, France, 19 December 1799. He lived at St. Paul, Minnesota, 22 February 1857. He made his preparatory studies in the Petits seminaires of Meximieux (Ain) and Saint-Genis-l'Argentiere (Rhone), his studies of philosophy at Alix (Rhone), and of theology in the seminary of Saint-Sulpice, Paris. He was ordained priest 20 December 1823, and soon was appointed vicar in the parish at Ferney, once the home of Voltaire, and eventually became its parish priest. He built there a new church and founded a boys' college with funds gathered on a tour through France. At this period, he revived the Catholic faith among many indifferent parishioners, who were made indifferent by the surviving influence of Descartes, and the proximity of the Protestant cantons of Switzerland. But Cretin longed for a larger field of activity; at one time he thought earnestly of going as a missionary to China. His perplexities in that regard were solved by the advent of Bishop Mathias Loras, first bishop of Dubuque, Iowa, who arrived in France in 1838 in search of priests for to evangelize his vast diocese. Cretin was one of the few who volunteered and on 16 August 1838, he secretly left his parish, embarked at Le Havre with Bishop Loras, and landed in New York in October of the same year. The winter of 1838-39 was spent in St. Louis, Missouri, and on his arrival in Dubuque, 18 April 1839, he was immediately appointed vicar-general of the new diocese. For over eleven years, he exercised his priestly ministry in these new regions, dividing his time between Dubuque, Prairie du Chien, Wisconsin, and the Winnebago Indians in the neighborhood of Fort Atkinson, in Winneshiek County, Iowa. Only once, in 1847, did he absent himself, when he made a trip to Europe in the interest of his missions. In 1850 St. Paul, Minnesota became the seat of a new diocese. Cretin was appointed its first bishop, and went to France, to be consecrated, 26 January 1851, at Belley by Bishop Devie, who had ordained him to the priesthood.
