Example Input: Question: In what country did Hermes study? Passage:From 1931, Hermes studied mathematics, physics, chemistry, biology and philosophy at the University of Freiburg. In 1937 he passed the state examination in Münster and was attending there in 1938 when the physicist Adolf Kratzer was present. After that he went on a scholarship to the University of Göttingen and then became an assistant at the University of Bonn. During World War II he was a soldier on the Channel Island of Jersey until 1943 and then on to the Chemical Physics Institute of the Navy in Kiel. At the end of the war he moved to Toplitzsee, where he was tasked with working on new encryption methods. In 1947, he became a lecturer at the University of Bonn where he took his habilitation, his thesis called Analytical manifolds in Riemannian areas. In 1949 he became a Professor at the University of Münster, where he turned back to the subject of mathematical logic.

Example Input: Question: Who produced the movie starring Christoper Reeve which used the idea of a prison for villians? Passage:Another common use of the theme is as a prison for villains or demons. The idea is used in the first two Superman movies starring Christopher Reeve where Kryptonian villains were sentenced to the Phantom Zone from where they eventually escaped. An almost exactly parallel use of the idea is presented in the campy cult film The Adventures of Buckaroo Banzai Across the 8th Dimension, where the "8th dimension" is essentially a "phantom zone" used to imprison the villainous Red Lectroids. Uses in horror films include the 1986 film From Beyond (based on the H. P. Lovecraft story of the same name) where a scientific experiment induces the experimenters to perceive aliens from a parallel universe, with bad results. The 1987 John Carpenter film Prince of Darkness is based on the premise that the essence of a being described as Satan, trapped in a glass canister and found in an abandoned church in Los Angeles, is actually an alien being that is the 'son' of something even more evil and powerful, trapped in another universe. The protagonists accidentally free the creature, who then attempts to release his "father" by reaching in through a mirror.
