[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: Which of Good Karma Brands' stations has the most listeners? Passage 1:Wyndham devoted much of his life to public service outside of his role in the Department of Education. In 1945 he led the Australian delegation at the conference which created UNESCO and was a member of the Australian delegation to UNESCO in 1958 and again in 1966. In 1959 he represented Australia at the Commonwealth Education Conference at Oxford and again in New Delhi in 1962. He was a Fellow of the Royal Institute of Public Administration and a Fellow and President (1963–1965) of the Australian College of Educators. He was Chairman of the NSW State Library Board, NSW State Archives Authority, Secondary Schools Board, Board of Senior School Studies, Board of Teacher Education, Sydney Symphony Orchestra Advisory Committee and Intellectually Handicapped Standing Committee amongst others. He was a member of the Senate of the University of Sydney, Council of the University of New South Wales, Council of the University of New England, Council of Macquarie University, Technical Education Advisory Council and the Sydney Opera House Trust. In 1961 Wyndham was appointed a Commander of the Order of the British Empire for services to education in NSW and in 1969 appointed a Knight Bachelor.
 Passage 2:He was a high school yokozuna at Saitama Sakae High School (also the alma mater of Gōeidō) and won multiple major amateur champions before his senior year at Nippon Sport Science University. If he had entered professional sumo in either of those years he would have started as a makushita tsukedashi and skipped the lower divisions, but his parents wanted him to complete his education. So instead he made his debut in March 2015 at the maezumō level. He was unable to compete under his family name of Nakamura as that was already taken by Nakamura Oyakata (former sekiwake Kotonishiki), so instead he used his given name, Daiki. He rose up the ranks quickly, winning the yūshō or tournament championships in the jonidan and sandanme divisions with perfect 7-0 records. He became a sekitori upon reaching the jūryō division in July 2016, and he won the jūryō championship in September with a 12–3 record, which saw him promoted to the top makuuchi division. His rise to the top division in ten tournaments was the second fastest of modern times behind that of Jōkōryū who achieved the feat in nine tournaments in 2012. At this point he changed his shikona from Daiki to Hokutofuji, which was derived from the shikona of his stablemaster, former yokozuna Hokutoumi, and Hokutoumi's own stablemaster, former yokozuna Kitanofuji.

[EX Q]: Question: How old was the commander Egon Mayer replaced as commander of JG 2? Passage 1:The American Locomotive Company (ALCO) assigned Kuhler to its advertising department in 1931 and commissioned him as a design consultant the following year. His first task was restyling the exterior trim of ALCO's Diesel switcher HH600 that persisted through all following variants. The next task established Kuhler's worldwide fame. The Milwaukee Road wanted a high-speed train for the competitive route between Chicago and Minneapolis. The cars were built in the company's shops, and the four A class locomotives were built by ALCO. Kuhler embellished their inverted bathtub look by a carefully colored livery. These Hiawatha trains became the fastest passenger service in the world by 1935. He had also designed the cars' interior, including the napkins and draperies in the dining car. His finned Beaver Tail observation car of the next generation was sensational, as were again the streamlined second-generation Milwaukee Road class F7 4-6-4 passenger locomotives designed by Kuhler. Also he designed the ALCO DL-109, the predecessor of world-famous ALCO PA diesel locomotives. He also designed Southern Railway (U.S.) Ps-4 class number 1380's streamlined appearance for The Tennessean in 1941. The 1380 was Southern's only streamlined steam engine.
 Passage 2:Formichetti is a prominent current member of the Haus of Gaga and his collaboration with Lady Gaga as her stylist or fashion director began in early May 2009 at a shoot with photographer Sebastian Faena for the July 2009 issue of V Magazine (V60), Formichetti saying that "It was an instant love." This was soon followed by a cover shoot for V61 (September issue) with Mario Testino. The following June he was fashion director for her performance at the 2009 MuchMusic Video Awards, and following that for the majority of Lady Gaga's important performances and appearances in the second half of 2009, including at the 2009 MTV Video Music Awards in September, where she appeared in four dresses by Jean-Paul Gaultier and one by Alexander McQueen, then on Saturday Night Live in October, where she appeared in a metal orb structure designed by Nazir Mazhar, and later at the Royal Variety Performance in December, where she appeared in a latex dress, by Atsuko Kudo, designed to resemble those worn by Elizabeth I of England, for Gaga's introduction to her namesake Elizabeth II. In the fall she also appeared in the third volume of Vogue Hommes Japan, the editorial titled "Lady Gaga & Araki's Tokyo Love" shot by Nobuyoshi Araki, with fashion direction by Formichetti. Their first collaboration in a music video together, for "Bad Romance", directed by Francis Lawrence, would later be voted Video of the Year and then win the Grammy Award for Best Short Form Music Video. In this Gaga appears in several outfits and footwear by Alexander McQueen, reappears in the orb by Nazir Mazhar, as well as in a "diamond crown" outfit by Franc Fernandez, and one by her creative team—the Haus of Gaga—among other pieces. Formichetti is also credited as stylist for her album The Fame Monster (shot by Hedi Slimane), and has been fashion director for her sold-out The Monster Ball Tour.
 Passage 3:Mayer claimed his first victories over United States Army Air Forces (USAAF) four-engine bombers when he shot down two B-17 Flying Fortresses and a B-24 Liberator on 23 November 1942. Together with fellow fighter ace Georg-Peter Eder, Mayer developed the head-on attack as the most effective tactic against the Allied daylight heavy combat box bomber formations. He received the Knight's Cross of the Iron Cross with Oak Leaves on 16 April 1943 after 63 victories. On 1 July 1943, he replaced Walter Oesau as commander of JG 2. He claimed his 90th victory on 31 December 1943 and on 5 February 1944 became the first pilot on the Channel Front to reach 100 victories. Mayer was killed in action on 2 March 1944 while leading an attack on a USAAF bomber formation; he was shot down by P-47 Thunderbolt escort fighters near Montmédy, France. He was posthumously awarded the Knight's Cross of the Iron Cross with Oak Leaves and Swords.
