Question: How many companies have offices in the tallest building in Dubai? Passage 1:Dubai, the largest city in the United Arab Emirates, is home to many modern high-rises, 108 of which stand taller than . The tallest building in Dubai is the Burj Khalifa, which rises and contains 163 floors. The tower has stood as both the tallest building in the world and the tallest man-made structure of any kind in the world since its completion in January 2010. The second-tallest building in Dubai is the Marina 101, which also stands as the world's second tallest residential skyscraper. The skyscrapers of Dubai are, for the most part, clustered in three different locations. The land along E 11 Road was the first to develop, followed by the Dubai Marina neighborhood and the Business Bay district.
 Passage 2:Montenegro has no currency of its own. As a constituent republic of the Socialist Federal Republic of Yugoslavia following World War II, and later of the Federal Republic of Yugoslavia, the Yugoslav dinar was the official currency in Montenegro. In November 1999, the government of Montenegro unilaterally designated the Deutsche Mark as its co-official currency with the dinar, and on 1 January 2001 the dinar officially ceased to be a legal tender in Montenegro. When the euro was introduced and the Deutsche Mark yielded, Montenegro followed suit and began using the euro as well, with no objection from the European Central Bank (ECB). The European Commission and the ECB have since voiced their discontent over Montenegro's unilateral use of the euro on several occasions.” A statement attached to their Stabilisation and Association Agreement with the EU read: "unilateral introduction of the euro was not compatible with the Treaty." The EU insists on the strict adherence to convergence criteria (such as spending at least 2 years in the ERMII system) which are not negotiable before euro adoption, but have not intervened to stop the unilateral adoption of the euro by Montenegro in 2002.
 Passage 3:In the 18th century, England was famous for its woollen and worsted cloth. That industry, centred in the east and south in towns such as Norwich, jealously protected their product. Cotton processing was tiny: in 1701 only of cottonwool was imported into England, and by 1730 this had fallen to . This was due to commercial legislation to protect the woollen industry. Cheap calico prints, imported by the East India Company from Hindustān (India), had become popular. In 1700 an Act of Parliament passed to prevent the importation of dyed or printed calicoes from India, China or Persia. This caused demand to switch to imported grey cloth instead—calico that had not been finished—dyed or printed. These were printed with popular patterns in southern England. Also, Lancashire businessmen produced grey cloth with linen warp and cotton weft, known as fustian, which they sent to London for finishing. Cottonwool imports recovered though, and by 1720 were almost back to their 1701 levels. Again the woollen manufacturers, in true protectionist fashion, claimed that the imports were taking jobs away from workers in Coventry. The Woollen, etc., Manufactures Act 1720 was passed, enacting fines against anyone caught wearing printed or stained calico muslins. Neckcloths and fustians were exempted. The Lancashire manufacturers exploited this exemption; coloured cotton weft with linen warp were specifically permitted by the 1736 Manchester Act. There now was an artificial demand for woven cloth.

Question: What was the size of Princeton's endowment the year Beale was born? Passage 1:Un'yō  was one of the ships dispatched to Kyūshū in 1874 during the Saga Rebellion. In May 1875, she carried diplomats to Busan in Korea in an attempt by the Japanese government to open diplomatic relations with the Joseon dynasty government. After they were rebuffed in these negotiations, the Japanese government again dispatched Un'yō in September 1875 under the command of Inoue Yoshika to provoke a military response, in what was later termed the Ganghwa Island incident. This eventually led to the Treaty of Ganghwa, which opened the Korean Peninsula to Japanese trade. In 1876, Un'yō  was assigned to assist in the suppression of the Hagi Rebellion, another uprising of disaffected former samurai. Un'yō  was severely damaged when she ran aground off the coast of the Kii Peninsula, and was scrapped the following year.
 Passage 2:Beale was born in 1948 in St. Louis County, Minnesota to C. Gordon Beale, a minister of the United Church of Christ, and Marcella Beale, a nurse. He served in the United States Army as a medic in the early 1970s and was honorably discharged. Beale attended the University of California, Riverside, earning a bachelor's degree in political science in 1975, using resources provided by the G.I. Bill. Beale interned for Democrat US Senator John V. Tunney while in college, assisting in the negotiation of the Bilingual Courts Act. He later simultaneously earned a Master of Public Administration from Princeton University and a law degree from New York University. Beale was employed with a law firm consisting of three partners in Lake City, Minnesota for four years prior to his work with the EPA. During his time with this law firm, he primarily dealt with the Federal Election Commission and the Securities and Exchange Commission.
 Passage 3:Cecil's success in 2011 was partly due to his training of the Khalid Abdullah-owned Frankel. In the 2010 season Frankel won the Royal Lodge Stakes and Group One Dewhurst Stakes. The following year he continued unbeaten, winning the Greenham Stakes, the 2,000 Guineas, the St. James's Palace Stakes at Royal Ascot, the Sussex Stakes and the Queen Elizabeth II Stakes. His six length victory in the 2,000 Guineas was described as "one of the greatest displays on a British racecourse". After his win in the Sussex Stakes Cecil himself described Frankel as "the best horse I've ever seen". Timeform and the International Federation of Horseracing Authorities rated him the best horse in the world. In his four-year-old season Frankel won the Group One Lockinge Stakes at Newbury before an eleven length victory in the Queen Anne Stakes at Royal Ascot, described in one national newspaper as "possibly the best single performance by any horse, on any track, since three Arabian stallions were imported into Britain to found the thoroughbred breed in the early years of the 18th century". Timeform raised their rating to 147, making Frankel the highest rated horse in their history. He won a second Sussex Stakes, at odds of 1–20, and then stepped up in distance to win by seven lengths the Juddmonte International Stakes at York over 10 furlongs. In October 2012 Frankel won the Champion Stakes at Ascot to finish his career unbeaten. "He's the best I've ever had, the best I've ever seen", Cecil told the BBC after the race, "I'd be very surprised if there's ever been a better."

Question: How many times was the capital of Eastern Wu moved between 221 and when Sun Hao moved it? Passage 1:Following his arrest, Sandford was held in the Nevada Southern Detention Center. Due to his mental health conditions, Sandford was kept in solitary confinement and repeatedly put under suicide watch. On June 20, 2016, a complaint was filed with the United States District Court for the District of Nevada charging Sandford with committing an act of violence on restricted ground. Sandford appeared in a Nevada District Court on June 20, 2016, where he was charged with committing an act of violence on restricted ground. Sandford's public defender, Heather Fraley, argued that Sandford should be bailed to a halfway house given his lack of a criminal record, but he was denied bail by judge George Foley Jr. on the basis that he presented a flight risk and was a potential danger to the community. On June 29, a federal grand jury responded to an indictment filed by United States Attorney Daniel Bogden by charging Sandford with three felonies: two counts of being an illegal alien in possession of a firearm and one count of impeding and disrupting the orderly conduct of government business and official functions. Each charge carried a maximum sentence of 10 years' imprisonment and a fine of $250,000. U.S. Immigration and Customs Enforcement also issued a detainer against Sandford relating to an immigration violation.
 Passage 2:However, the Turkish Navy later changed its plan and opted for a fully equipped flight deck with the ski-jump ramp in front, after deciding to purchase F-35B STOVL aircraft. Turkey is a Level 3 partner in the Joint Strike Fighter program and the Turkish Air Force will get the F-35A CTOL version. The Turkish version of the LHD will be capable of operating up to 12 F-35Bs and 12 helicopters in "light aircraft carrier" configuration. The dimensions of the final design are: 232 meters (length), 32 meters (beam), 6.9 meters (draught), and 58 meters (height). Its displacement will be 24,660 tons (in "light aircraft carrier" mission configuration) or 27,079 tons (in "LHD" mission configuration). Its maximum speed will be 21.5 knots (in "light aircraft carrier" configuration) or 29 knots (in "LHD" configuration); while its maximum range will be 9000 miles at economical speed. It will have a 5,440 m² flight deck and a 990m² aviation hangar which can accommodate either 12 medium size helicopters or 8 CH-47F Chinook heavy-lift helicopters. (When the aviation hangar and the light cargo garage are unified, the ship can carry up to 25 medium size helicopters. Alternatively, the ship can carry up to 12 F-35B and 12 helicopters. Six more helicopters can be hosted on the flight deck of the ship.) Additionally, the ship will have a 1,880 m² light cargo garage for TEU containers and 27 Amphibious Assault Vehicles (AAV); a 1,165 m² dock which can host four Landing Craft Mechanized (LCM) or two Landing Craft Air Cushion (LCAC), or two Landing Craft Vehicle Personnel (LCVP); and a 1,410m² garage for heavy loads, which can host 29 Main Battle Tanks (MBT), Amphibious Assault Vehicles and TEU containers. The ship's crew will consist of 261 personnel: 30 officers, 49 NCOs, 59 leading seamen and 123 ratings.
 Passage 3:In 221, warlord Sun Quan moved the capital of Eastern Wu from Gong'an county, Jingzhou (northwest of present-day Gong'an county, Hubei) to È county (in present-day Ezhou City), and renamed È to Wuchang (literally prospering from military, regarding its logistics role of the military bases established before the Battle of Red Cliffs). Later in the year Cao Pi proclaimed himself the emperor of Cao Wei. Sun Quan declared independence in the following year, and started to build forts and palaces in Wuchang. Sun Quan proclaimed himself the emperor of Eastern Wu in 229, and moved the capital to Jianye. Sun Hao, the emperor of Eastern Wu between 264 and 280, moved the capital back to Wuchang in 265. In 589, the Wuchang commandery was abolished and the Wuchang county was transferred to a new commandery named Ezhou (headquartered in present-day Wuchang District), and remained in the administration since then.
