[EX Q]: 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.

 Passage 2:In 2000, Schlesinger played in all 16 games for the fifth time in six NFL seasons and second year as the Lions' starting fullback. His 15 special teams tackles tied for fifth on squad as well. In 2001, the Lions named Marty Mornhinweg head coach and the team moved away from a power rushing attack to the west coast offense.

 Passage 3:DeGolyer opened a petroleum geology consultancy in 1914, moving to Montclair, New Jersey to work in New York City in 1916. In 1919, while working as a consultant to the British entrepreneur Lord Cowdray, DeGolyer negotiated the sale of the El Aguila company to Royal Dutch Shell. In the same year, DeGolyer organized the formation of the Rycade Oil Company as well as the Amerada Petroleum Corporation for Lord Cowdray, rising to become general manager, president, and chairman from 1929 to 1932 DeGolyer left the firm in 1932, but remained with Rycade, which was established to explore salt dome oil deposits through 1941. As a geophysical consultant with Rycade, DeGolyer made the first torsion balance survey in the United States at the Spindletop oilfield. An oilfield found by DeGolyer on behalf of Rycade at Nash, Texas was the first oilfield anywhere to be discovered using geophysics. From 1925 DeGolyer established the Geophysical Research Corporation as a subsidiary of Amerada to develop reflection seismology techniques originated by J. Clarence Karcher and Eugene McDermott, leaving in 1932 to move to Dallas, Texas. DeGolyer provided financial support for the 1930 establishment of GRC's successor, Geophysical Service Incorporated. GSI went on to spin off Texas Instruments. In 1936 with Lewis MacNaughton, DeGolyer established the petroleum exploration consulting firm DeGolyer and MacNaughton, and Core Laboratories, Incorporated the same year to provide drilling core and fluids analysis. DeGolyer was also associated with the Atlatl Royalty Company from 1932 to 1950 and the Felmont Corporation in 1934. In 1956 he established Isotopes, Incorporated to provide radioactive isotopes for oilfield and industrial purposes.

[EX Q]: Question: Which team had a better win/loss record the year that Jackson won the Hamburg Masters, Germany or Scotland? Passage 1:As its name suggests, Port Charles is a major port. The Waterfront district has been under the control of Sonny Corinthos for over a decade, though rival gangs have tried to move in on his territory, such as Lorenzo Alcazar, the Ruiz brothers, and others. Kelly's, a local eatery, is located in this area and the Elm Street Pier is also located here. Majority of the Port Charles waterfront is owned by the Pride-Philips Company, which was given to Courtney Matthews as a thank you from a woman whose life she saved. Courtney later sold Pride-Philips to Lorenzo Alcazar. In 2008, Alexis Davis and Sam McCall are attacked here by the Text Message Killer. On March 17, 2008, one of the warehouses on the docks, an abandoned cannery, exploded. Sonny met with Claudia Zacchara to return Johnny to her. She arrived, and got on the phone with an ally to try and peace with them and Sonny. Meanwhile, Trevor Lansing and sniper stood on a loft in the warehouse, poised to shoot Claudia. Ric Lansing and Marianna Erosa were in another part of it, trying to cover the dead body of Randy. Carly finally finds Michael, where he confesses to shooting Kate Howard. They began to leave and go home. Meanwhile, a bomb is slowly ticking away. Right as the sniper pulls his trigger, the bomb goes of, and an explosion rips through the building. Everyone survives the event, but Carly miscarries her baby. Soon after The Docks became the site of a fake prescription drug ring headed up by Jerry Jacks. The ring produced placebos that claimed at least one life; a female heart patient. Matt Hunter was the prime suspect, but the extent of his involvement cleared. Andrei Karpov had a cargo ship, Odyssey, docked in the harbor.
 Passage 2:Initially called Camp Annapolis Junction, the post was opened as "Camp Admiral" in 1917 on acquired for a training camp. The post was called Camp Meade Cantonment by 1918, Camp Franklin Signal Corps school was located there and in 1919, the Camp Benning tank school—formed from the World War I Camp Colt and Tobyhanna schools—was transferred to the fort before the Tank Corps was disbanded. Renamed to Fort Leonard Wood (February 1928 – March 5, 1929), the fort's Experimental Motorized Forces in the summer and fall of 1928 tested vehicles and tactics in expedition convoys (Camp Meade observers had joined the in-progress 1919 Motor Transport Corps convoy). In 1929, the fort's 1st Tank Regiment encamped on the Gettysburg Battlefield. During World War II, Fort Meade was used as a recruit training post and prisoner of war camp, in addition to a holding center for approximately 384 Japanese, German, and Italian immigrant residents of the U.S. arrested as potential fifth columnists. The Second U.S. Army Headquarters transferred to the post on June 15, 1947; and in 1957, the post became headquarters of the National Security Agency.
