Q: Question: How many stories high is the tower Trump built? Passage 1:Fred Trump was one of the biggest real estate developers in New York. Using their inheritance, Fred and his mother Elizabeth founded E. Trump & Son. Fred married Mary MacLeod (19122000), a native of Tong, a small village near Stornoway, in the Western Isles of Scotland. She was the daughter of fisherman Malcolm MacLeod and Mary MacLeod (nee Smith). At age 17, she immigrated to the United States and started working as a maid in New York. Fred and Mary met in New York and married in 1936, settling together in Queens. Mary became a U.S. citizen in 1942. Fred was the father of the businessman Donald Trump, who became president of the real estate company in 1971, and renamed it the Trump Organization. Donald Trump has said that he is "proud" of his German heritage, having served as grand marshal of the 1999 German-American Steuben Parade in New York City. While walking through the city and seeing Trump Tower, Donald Trump recalled saying: "This is a long way from Kallstadt."
Passage 2:Selling studied mathematics at the Universities of Gottingen and Munich (under Philipp Ludwig von Seidel). He obtained the doctorate in Munich in 1859, under the supervision of Bernhard Riemann. On recommendation of Leopold Kronecker he became professor extraordinarius of mathematics at the University of Wurzburg in 1860 against the will of the philosophical faculty and the mathematics professor Aloys Mayr. There, he also taught astronomy and became conservator-restorer at the astronomical department in 1879. In 1873 he wrote an important paper on binary and ternary quadratic forms which was also translated into French and cited by Henri Poincare, Emile Picard and Paul Gustav Heinrich Bachmann. Beginning with 1877 he also became concerned with insurance, and participated in the reorganization of the pensions in Bavaria on behalf of the Bavarian government. His application for a promotion to professor ordinarius was declined in 1891. In 1906 he became emeritus.
Passage 3: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.
