[EX Q]: Question: How long did it take to build the second tallest building in Dubai? Passage 1: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 2: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 3: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.

[EX Q]: Question: Who is the oldest shooter to have won three Olympic individual gold medals? Passage 1:Randall enlisted as a private in the 4th Pennsylvania Volunteer Infantry in the April 1861. He then accepted appointment to the 4th U.S. Infantry as second lieutenant in October. He served in New York and Washington, D.C., and in the field with the Army of the Potomac. He was a second lieutenant at the Siege of Yorktown, Battle of Gaines' Mill, Battle of Malvern Hill, Second Bull Run (where he commanded Company C), and Fredericksburg; and a first lieutenant at the Battle of the Wilderness. He was appointed a brevet captain for gallant service in the Battle of Antietam. He served as a major in the 14th New York Heavy Artillery Regiment, part of Major General Ambrose Burnside's IX Corps on the Richmond-Petersburg Front in 1864, and was commander of the regiment at the Battle of the Crater. The Dansville Advertiser reported on 7 September that he assumed command of the regiment on 18 August. This article also reports that he was wounded in the battle on 19 August. He was appointed a brevet lieutenant colonel, and then colonel for gallantry in the Battle of Fort Stedman. He mustered out of the Volunteer service on 26 August, and was appointed captain in the 4th US Infantry on 23 September 1865. Subsequently, he served at Davids' Island Military Reservation, New York Harbor, where he was in December 1867.
 Passage 2:In July 2008, Kamloops MLA Claude Richmond announced he would not seek re-election in the May 2009 provincial election. Consequently, Lake announced that he would not stand for re-election as mayor but would instead seek to replace Richmond. With MLA Kevin Krueger moving to the new Kamloops-South Thompson riding, Lake was unopposed for BC Liberal nomination in the Kamloops-North Thompson. The election was expected to be close but Lake ultimately defeated the NDP candidate Doug Brown, student April Snowe for the Green Party, Clearwater resident Wayne Russell of the Refederation Party, and the Work Less Party's Keston Broughton. Lake's BC Liberals won the election and formed a majority government under Premier Gordon Campbell. In the first two sessions of the 39th Parliament Lake was appointed to the Select Standing Committee on Aboriginal Affairs and the Select Standing Committee on Health, however neither of those committees held any meetings. Premier Campbell did not include Lake in the cabinet but he was appointed as the Parliamentary Secretary for the Ranching Task Force under the Ministry of Agriculture and Lands. The Ranching Task Force began its work in July to review the province's role in the ranching industry, an industry which had been facing setbacks such as declining cattle prices and fewer exports following a Bovine spongiform encephalopathy outbreak and a strengthen currency value (relative to the US dollar). The task force's final report and recommendations were sent to the Minister of Agriculture and Lands in November 2009.
 Passage 3:On 28 July 2012, Jin won the gold medal in the men's 10 m air pistol at the 2012 Summer Olympics. On 5 August, he won the gold medal in the 50m, becoming the first man to successfully defend the 50-metre pistol Olympic title. By doing so, Jin also became the first man to win the 10 metre air pistol and 50 metre pistol gold medals at the same Olympics, and one of the five shooters to win two individual gold medals at one Olympics, being the first man to have done so since Otto Olsen of Norway at the 1920 Summer Olympics. He is one of three shooters to have won three Olympic individual gold medals, along with Ralf Schumann of Germany and Kim Rhode of the United States. He became the first Korean athlete to win three individual Olympic gold medals, to win four (and five) individual Olympic medals, to defend an individual title in the Summer Olympics (while Sim Kwon-Ho won Olympic gold medals for Greco-Roman wrestling in 1996 and 2000, he won two different weight divisions), to win two individual gold medals at one Summer Olympic Games and to win an individual medal for one event at three consecutive Olympic Games (Kim Soo-Nyung won individual gold, silver and bronze medals respectively for archery in the 1988, 1992 and 2000 but these Olympics were non-consecutive).

[EX Q]: Question: Who was the head monk at Alvastra Abbey when Stephen lived there? Passage 1:Shortly after he returned to England in bad health. From 1777 to 1779 he commanded , as flag captain to his father at Newfoundland. On his return he was appointed to the 32-gun frigate HMS Pearl, which when cruising near the Azores on 14 September 1779, captured the Spanish frigate Santa Monica of equal force. In December Pearl sailed with the fleet under Sir George Rodney, and assisted in the capture of the Caracas convoy; but having sprung her foremast, was ordered home with the prizes. She was afterwards sent out to North America, and on 30 September 1780, while on a cruise off the Bermudas, captured the Espérance, a frigate-built privateer of 32 guns. In the battle of Cape Henry, on 16 March 1781, she acted as repeating frigate. She was not with the fleet during the battle of the Chesapeake on 5 September, but joined it, still off Cape Henry, on the 14th, and was left to keep watch on the movements of the French till the 25th, when she sailed for New York. On 19 October she sailed again with the fleet, and on the 23rd was stationed ahead as a look-out (Pearl's Log). She returned to England in 1782.
 Passage 2:The first Archbishop of Uppsala was Stephen, a Cistercian monk from the celebrated Alvastra Abbey. Cardinal William of Sabina came as papal legate to Sweden during the archiepiscopate of Jarler, a Dominican friar (1235–55). The legate had been commissioned, among other things, to establish cathedral chapters wherever such were lacking, and to grant them the exclusive right of electing the bishops. Another important matter which the legate had been ordered to carry out was the enforcement of the law of clerical celibacy. At a provincial synod held at Skänninge in 1248 under the presidency of the cardinal, the rules as to celibacy were made more severe. The pious and energetic Archbishop Jarler and his successor Laurentius (1257–67), a Franciscan, constantly strove to elevate the clergy and to enforce the law of celibacy. A century later Saint Bridget (d. 1373), laboured zealously for the enforcement of the same law.
 Passage 3:Held against the backdrop of the 2008 Serbian presidential elections — contested between incumbent Boris Tadić from the ruling center-left Democratic Party (DS) and challenger Tomislav Nikolić from the opposition right-wing Serbian Radical Party (SRS) — as well as speculation that Albanians from Serbia's province of Kosovo were in the final stages of coordination with the United States to unilaterally declare independence, the festival received plenty of attention both in the Serbian and foreign press. Political angles and overtones dominated foreign press reports such as the one by in center-left Libération who, after giving praise to the festival for celebrating auteur cinema, wondered if the fact that festival's jury is headed by Peter Handke — whom she described as someone "who still smelled of sulfur after being at Milošević's funeral and who wrote about Serbs in panegyric form due to seeing them unjustly accused of all evils" — also mean that Kusturica adheres to these ideas. She answers her own question by saying that, like Handke, Kusturica also believes western Europeans have demonized Serbs and Serbia, but that the Serbian director supports center-left candidate Tadić at the presidential elections.
