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 Munster and was attending there in 1938 when the physicist Adolf Kratzer was present. After that he went on a scholarship to the University of Gottingen 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 Munster, where he turned back to the subject of mathematical logic.

Example Input: Question: How old were Norman Tindale and Joseph Birdsell when they published their paper about the 12 Negrito tribes? Passage:In a publication of 1941, Norman Tindale, together with the American anthropologist Joseph Birdsell, published a paper suggesting that there were 12 Negrito tribes living on the coastal and rainforest areas around Cairns. The idea had been developed by Birdsell during field work in 1937-8. They were characterized by very short stature, curly hair, and yellowy-brown skin. Six of them were Dyirbal speakers, such as the Jirrbal, Girramay, Gulngai and Djiru within the Murray Upper/Tully Area. Of the others, located further north beyond Cairns, two spoke varieties of Djabugay, and three spoke dialects of Yidin. The remaining tribe were the Mbabaram, whom Tindale took to be strong evidence for his hypothesis because their language, in so far as it had been reported, diverged substantially from the surrounding tongues, and appeared to be wholly atypical, compared to the standard Australian aboriginal languages.
