Input: Consider Input: Question: In which country did Hue attend college? Passage:Robert Hues (1553 – 24 May 1632) was an English mathematician and geographer. He attended St. Mary Hall at Oxford, and graduated in 1578. Hues became interested in geography and mathematics, and studied navigation at a school set up by Walter Raleigh. During a trip to Newfoundland, he made observations which caused him to doubt the accepted published values for variations of the compass. Between 1586 and 1588, Hues travelled with Thomas Cavendish on a circumnavigation of the globe, performing astronomical observations and taking the latitudes of places they visited. Beginning in August 1591, Hues and Cavendish again set out on another circumnavigation of the globe. During the voyage, Hues made astronomical observations in the South Atlantic, and continued his observations of the variation of the compass at various latitudes and at the Equator. Cavendish died on the journey in 1592, and Hues returned to England the following year.

Input: Consider Input: Question: What was the final rank of the U.S. Army officer who drove the Navajo people out of the their ancestral homeland? Passage:The Navajo War was not directly a part of the Black Hawk War, but it may have been a source of some of the native warriors who fought in the Black Hawk War. Black Hawk's success drew fighters from other Utes in Colorado, Apaches from New Mexico, and many Navajos. In the winter of 1866 Black Hawk and his band went to the Four Corners region where he received many new recruits. So many Navajos joined him that they formed almost half his raiders. The Navajo had been decimated by the U.S. Army under Kit Carson and forced out of their ancestral homeland. The remaining Navajos were eager for a chance to build up their herds at the expense of white settlers. Manuelito, the most important chief refusing to relocate to the Bosque Redondo Reservation, jointly led Black Hawk's raids on Mormon settlements in southern Utah during 1866. The attacks commenced at Pipe Springs, then a Mormon settlement on the Arizona-Utah border. The retaliation for the Pipe Springs raid left four unarmed Paiutes dead for murders they had nothing to do with. This brought some Paiute fighters to Black Hawk's band. Hopis hearing of the Navajo's movements feared they were to be attacked and struck first ambushing Manuelito's Navajos. The raids continued at the Paria settlements, and Kanab, who sent pleas for help against the raids. In subsequent years, the raids continued in the south by Navajos and Paiutes, which raised tensions to a fever pitch which would result in the worst massacre of the war at Circleville. Chief Kanosh predicted that in 1867 six thousand Navajos would wipe out the Mormon towns in southern Utah.
