Example Input: Question: Who was the founder of the school where Constant Mews studied for his doctorate? Passage:Mews attended the University of Auckland and completed BA and MA degrees there in History. He carried out doctoral study at the University of Oxford, followed by five years (1980–1985) teaching British civilisation at the Universite de Paris III, while pursuing studies in medieval thought (focusing on Peter Abelard) in connection with Jean Jolivet, at the École pratique des hautes études en sciences religieuses. This was followed by two years as a Leverhulme research fellow at the University of Sheffield on editing the writings of Peter Abelard. Mews took up a position at Monash University as Lecturer in the Department of History in July 1987. He became involved in developing the Centre for Studies in Religion and Theology and in promoting studies in religion more generally, with a strong interest in interfaith work. He has had spells of study at the Institute for Advanced Study, Princeton, in 1990 and 2000, and has also again taught in Paris, at the École pratique des hautes études (Ve section) and in the École des hautes études en sciences sociales.

Example Input: Question: Who was the leader of Hungary during the Hungarian Revolution of 1848? Passage:The last meetings had revealed the rising antagonism with Britain and France, especially on Italian unification, the right to self-determination and the Eastern Question. The Alliance is conventionally taken to have become defunct with Alexander's death in 1825. France ultimately went her separate way after the July Revolution of 1830, leaving the core of Russia, Austria and Prussia as Central-Eastern European block which once again congregated to suppress the Revolutions of 1848. The Austro-Russian alliance finally broke up in the Crimean War: though Russia had helped to completely destroy the Hungarian Revolution of 1848, Austria did not take any action to support her ally, declared herself neutral and even occupied the Wallachian and Moldavian lands on the Danube upon the Russian retreat in 1854. Thereafter, Austria remained isolated, which added to the loss of her leading role in the German lands, culminating in the defeat of the Austro-Prussian War in 1866.
