Example Input: Question: Was the head of the Swedish Institute for Race Biology still alive hen Gunther was professor at Albert Ludwigs University? Passage:In 1919, after the end of the war, he started his writing career. He wrote a polemical work entitled "The Knight, death and the devil: the heroic idea", a reworking of the tradition of German Pagan-Nationalist Romanticism into a form of "biological nationalism". Heinrich Himmler was very impressed by this book. In 1922 Gunther studied at the University of Vienna while working in a museum in Dresden. In 1923 he moved to Scandinavia to live with his second wife, who was Norwegian. He received scientific awards from the University of Uppsala and the Swedish Institute for Race Biology, headed by Herman Lundborg. In Norway he met Vidkun Quisling. In May 1930 he was appointed to the University of Jena by Wilhelm Frick who had become the first NSDAP minister in a state government when he was appointed minister of education in the right-wing coalition government formed in Thuringen following an election in December 1929. In 1935 he became a professor at the University of Berlin, teaching race science, human biology and rural ethnography. From 1940 to 1945 he was professor at Albert Ludwigs University.

Example Input: Question: Who plays Spiderman in the movie that Topher Grace appeared in in 2007? Passage:Eric is a well-known fan of science fiction, such as and especially Star Wars, in which he compares himself to Luke Skywalker. He is also known to have a large, beloved collection of G.I. Joe. He listens to artists such as Led Zeppelin, KISS, Aerosmith, Pink Floyd, Lynyrd Skynyrd, Deep Purple, Queen, Styx and Rush. He is also a Beatles fan and has been known to liken his group of friends to them, accusing Jackie of "breaking up the band" with her romantic entanglements with Kelso and Hyde (calling her Yoko, in reference to Yoko Ono). It is also hinted that he is both a Batman and Spider-Man fan, having Spider-Man bed sheets and a considerable number of comic books, most of them bearing the Marvel Comics logo with the titular character on the covers. When he fights a fan at the Packers game, he tells Red that he learned his moves from Spider-Man; coincidentally, Topher Grace starred as Eddie Brock, a character who obtains powers very similar to Spider-Man, thus transforming him into the monstrous Venom in Spider-Man 3 in 2007.
