Example Input: Question: When was the city founded that houses the university Sluyter teaches in? Passage:Andrew Sluyter is an American social scientist who currently teaches as a professor in the Geography and Anthropology Department of the Louisiana State University in Baton Rouge. His interests are the environmental history and historical, cultural, and political ecology of the colonization of the Americas. He has made various contributions to the theorization of colonialism and landscape, the critique of neo-environmental determinism, to understanding pre-colonial and colonial agriculture and environmental change in Mexico, to revealing African contributions to establishing cattle ranching in the Americas, and to the historical geographies of Hispanics and Latinos in New Orleans. With the publication of Black Ranching Frontiers: African Cattle Herders of the Atlantic World, 15001900 (Yale University Press, 2012) and a 201213 Digital Innovation Fellowship from the American Council of Learned Societies, he has joined a growing number of scholars from multiple disciplines working from the perspective of Atlantic History and using the tools of the Digital Humanities. His latest book, Hispanic and Latino New Orleans: Immigration and Identity since the Eighteenth Century (LSU Press, 2015), co-authored with Case Watkins, James Chaney, and Annie M. Gibson, was awarded the 2015 John Brinckerhoff Jackson Book Prize by the American Association of Geographers.

Example Input: Question: What country claims ownership of the island the crew sheltered on after their ship's hull was crushed? Passage:He led the 1901-1904 Swedish Antarctic Expedition, aboard the ship Antarctic. The expedition visited the Falkland Islands before the ship, commanded by seasoned Antarctic sailor Carl Anton Larsen, dropped Nordenskjold's party off at Snow Hill Island, a small island off the coast of the Antarctic Peninsula. Nordenskiold overwintered at Snow Hill Island, while Antarctic returned to the Falklands. The following summer Larsen brought her south, intending to retrieve the Nordenskiold party, but she became trapped in ice which eventually crushed her hull, forcing Larsen and his crew to overwinter in a hastily constructed shelter on Paulet Island. Larsen and Nordenskjold finally rendezvoused at their fall-back rescue hut at Hope Bay in late 1903, where they were picked up by the Argentine Navy corvette ARA Uruguay (commanded by Julian Irizar), which had been dispatched when Antarctic had failed to make her appointed return to South America the previous year. Despite its end and the great hardships endured, the expedition was considered a scientific success, with the parties having explored much of the eastern coast of Graham Land, including Cape Longing, James Ross Island, the Joinville Island group, and the Palmer Archipelago. The expedition, which also recovered valuable geological samples and samples of marine animals, earned Nordenskjold lasting fame at home, but its huge cost left him greatly in debt.
