question:
Question: When did the person who voices Itchy begin acting professionally? Passage:The Itchy & Scratchy Show (often shortened as Itchy & Scratchy) is a fictional animated television series featured in the American animated television series The Simpsons. It appears as a part of The Krusty the Clown Show. Itself an animated cartoon, The Itchy & Scratchy Show depicts a blue mouse, Itchy (voiced by Dan Castellaneta), who repeatedly kills a black cat, Scratchy (voiced by Harry Shearer). The cartoon first appeared in The Tracey Ullman Show short "The Bart Simpson Show", which aired November 20, 1988. The cartoon's first appearance in The Simpsons was in the 1990 episode "There's No Disgrace Like Home". Typically presented as 15- to 60-second-long cartoons, the show is filled with gratuitous violence that almost invariably prompts uproarious laughter from Bart and Lisa. The Simpsons also occasionally features characters who are involved with the production of The Itchy & Scratchy Show, including Roger Meyers Jr. (voiced by Alex Rocco, and, later, Hank Azaria), who runs the studio and produces the show.

question:
Question: Who did Vinny Del Negro play for before he signed with the Spurs? Passage:The 1992–93 NBA season was the Spurs' 17th season in the National Basketball Association, and 26th season as a franchise. During the offseason, Terry Cummings suffered a serious knee injury and only played in the final eight games of the season. With the acquisition of Dale Ellis from the Milwaukee Bucks and signing free agent Vinny Del Negro, plus re-signing Avery Johnson after a brief stint with the Houston Rockets, the Spurs struggled with a 9–11 start to the season as new head coach Jerry Tarkanian was fired. After playing one game under Rex Hughes, the team hired John Lucas II as their new coach. At midseason, they acquired J.R. Reid from the Charlotte Hornets. Under Lucas, the Spurs would play solid basketball posting a 10-game winning streak in January, then winning eight straight in February, finishing second in the Midwest Division with a 49–33 record. David Robinson and Sean Elliott were both selected for the 1993 NBA All-Star Game.

question:
Question: Did Eduard Selling stay in Germany for his study? Passage:Selling studied mathematics at the Universities of Göttingen and Munich (under Philipp Ludwig von Seidel). He obtained the doctorate in Munich in 1859, under the supervision of Bernhard Riemann. On recommendation of Leopold Kronecker he became professor extraordinarius of mathematics at the University of Würzburg in 1860 – against the will of the philosophical faculty and the mathematics professor Aloys Mayr. There, he also taught astronomy and became conservator-restorer at the astronomical department in 1879. In 1873 he wrote an important paper on binary and ternary quadratic forms which was also translated into French and cited by Henri Poincaré, Émile Picard and Paul Gustav Heinrich Bachmann. Beginning with 1877 he also became concerned with insurance, and participated in the reorganization of the pensions in Bavaria on behalf of the Bavarian government. His application for a promotion to professor ordinarius was declined in 1891. In 1906 he became emeritus.
