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.

Example Input: Question: Who was the older, John C. Jacobs or his predecessor? Passage:The caucus of Democratic State legislators met on January 15, State Senator Albert P. Laning, of Buffalo, presided. All but one of the legislators were present, only Assemblyman John M. Roscoe, of Schoharie County, was sick. The caucus nominated Francis Kernan for the U.S. Senate. Kernan had been the Democratic/Liberal Republican candidate for Governor in November 1872 but had been defeated by John Adams Dix. Now Kernan was the choice of Tammany boss John Kelly who had succeeded the corrupt William M. Tweed. Kelly was opposed by John C. Jacobs, who proposed Ex-State Senator Henry C. Murphy, Jacobs's predecessor from the 3rd District, and the Democratic candidate who had lost the U.S. Senate elections in 1867 and 1869 when the Democrats were the minority. Kelly stood firm in his intention to dominate the Democratic Party, and had the caucus nomination made by viva voce vote instead of the more traditional secret ballot. Jacobs and Murphy had expected to get votes from many legislators who would not dare to cross Kelly openly, but had to abandon their hopes when the secret ballot was voted down 74 to 13.
