[EX Q]: Question: Which of the two labels that Laurie recorded for between 1947 and 1950 had the most hit records? Passage 1:Her singing career started by vocalising for two territory bands led by Dallas Bartley and Snookum Russell, on the Chitlin' Circuit. In 1945, she recorded a version of "Saint Louis Blues" with the Bartley led band for Cosmo Records. She relocated to New Orleans, Louisiana, and was engaged by Paul Gayten. In 1947, she was performing in concert in New Orleans with Gayten, when the latter asked the young Fats Domino to come and play "Swanee River Boogie" on stage. Recording for both the Regal and De Luxe labels between 1947 and 1950, Laurie sang on several sides backed by Gayten's orchestra. Her first success was with her version of "Since I Fell for You" (1947), of which recording studio owner Cosimo Matassa said: "Annie Laurie did the first really good record that I liked... [She] was just fantastic, I mean nobody will ever make another version like that." She followed its success up with "Cuttin' Out" (1949), "You Ought To Know" (1950), "I Need Your Love" (1950), "Now That You're Gone" (1950) and "I'll Never Be Free" (1950). Laurie also toured with Gayten's orchestra in 1951.
 Passage 2:Levin holds several patents in chip design and GPS-based authentication, and has published over 50 scientific papers and policy articles. His work has appeared in Foreign Affairs, Foreign Policy, HuffPost, Politico.com, and the Obama White House website. "How to Counter Fake News," an article Levin co-authored with former Governor of Maryland Martin O'Malley, was included in Foreign Affairs's "The Best of 2017" anthology. He has co-authored pieces on cybersecurity with retired General Wesley Clark, and with cybersecurity expert Dan E. Geer Jr.. He also wrote an article with former Under Secretary of Defense for Policy Michèle Flournoy that encourages the Federal Government to embrace practices that protect data and personal identity from the inside out. He recently collaborated with General H. Hugh Shelton and Stephen Ondra on a report that urges the Department of Defense to choose an open source electronic health record when reforming the Military Health System.
 Passage 3:Koreans in Vietnam is a community of Vietnam with a population of Korean expatriates along with Vietnamese citizens of Korean ancestry. The population initially came in a military capacity, fighting on both sides of the Vietnam War. After the end of the war, there was little Korean migration or tourism in Vietnam, until the rise of the South Korean economy and the decline of the North resulted in an influx of South Korean investors and North Korean defectors, as well as South Korean men seeking Vietnamese wives. As of 2011, according to statistics of South Korea's Ministry of Foreign Affairs and Trade, they numbered roughly eighty thousand people, making them the second-largest Korean diaspora community in Southeast Asia, after the Korean community in the Philippines, and the tenth-largest in the world. A more recent estimate from Vietnam Television says their population might be as large as 130,000.

[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: Which PC operating environment sold more from Microsoft? Passage 1:The Japanese exhibition at the fair was the product of years of preparation. The empire had received its invitation in 1871, close on the heels of the Meiji Restoration, and a government bureau was established to produce an appropriate response. Shigenobu Okuma, Tsunetami Sano, and its other officials were keen to use the event to raise the international standing of Japanese manufactures and boost exports. 24 engineers were also sent with its delegation to study cutting-edge Western engineering at the fair for use in Japanese industry. Art and cultural relics at the exhibit were verified by the Jinshin Survey, a months-long inspection tour of various imperial, noble, and temple holdings around the country. The most important products of each province were listed and two specimens of each were collected, one for display in Vienna and the other for preservation and display within Japan. Large-scale preparatory exhibitions with this second set of objects were conducted within Japan at the Tokyo Kaisei School (today the University of Tokyo) in 1871 and at the capital's Confucian Temple in 1872; they eventually formed the core collection of the institution that became the Tokyo National Museum. 
 Passage 2:Fawcus served during World War One and was promoted to the rank of lieutenant colonel in March 1915. He was made a member of the Order of St Michael and St George in the 1915 Birthday Honours. He was made a temporary colonel in April 1917. He awarded the Croix de guerre by France in June 1917. Throughout the course of the war, Fawcus was mentioned in dispatches six times. Following the war, he was promoted to the rank of brevet colonel in June 1919, and in the same year he served in the Third Anglo-Afghan War. He served as an assistant director-general at the War Office from June 1922–July 1926. He was appointed as the honorary physician to George V in January 1923, following the retirement of Sir Alfred Blenkinsop. He was promoted to the full rank of colonel in June 1926, with appointment in the same month as a deputy director-general at the War Office. He was promoted to the rank of major-general in October 1926. He was knighted in the 1928 Birthday Honours. He was appointed as the director-general of Army Medical Services in September 1929, at which point he was promoted to the rank of lieutenant-general. He was made a member of the Order of the Bath in the 1931 New Year Honours. Fawcus was presented with an honorary degree in civil law by Durham University in 1930. He served as the director-general of Army Medical Services until his retirement from active service in March 1934. Following his retirement he was replaced as the personal physician for George V by J. W. L. Scott. While serving as director-general, he won the General's Cup in golf at Sandwich in 1931.
 Passage 3:Due to the sales growth of IBM clones in the '90s, they became the industry standard for business and home use. This growth was augmented by the introduction of Microsoft's Windows 3.0 operating environment in 1990, and followed by Windows 3.1 in 1992 and the Windows 95 operating system in 1995. The Macintosh was sent into a period of decline by these developments coupled with Apple's own inability to come up with a successor to the Macintosh operating system, and by 1996 Apple was almost bankrupt. In December 1996 Apple bought NeXT and in what has been described as a "reverse takeover", Steve Jobs returned to Apple in 1997. The NeXT purchase and Jobs' return brought Apple back to profitability, first with the release of Mac OS 8, a major new version of the operating system for Macintosh computers, and then with the PowerMac G3 and iMac computers for the professional and home markets. The iMac was notable for its transparent bondi blue casing in an ergonomic shape, as well as its discarding of legacy devices such as a floppy drive and serial ports in favor of Ethernet and USB connectivity. The iMac sold several million units and a subsequent model using a different form factor remains in production as of August 2017. In 2001 Mac OS X, the long-awaited "next generation" Mac OS based on the NeXT technologies was finally introduced by Apple, cementing its comeback.
