[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 many productions did Courau's co-star in A slip of the Tongue appear? Passage 1:Mohammed and a Kenyan extremist, thought to be Musa Hussein (a.k.a. Musa Sambayo), were driving in a car carrying $40,000 in United States dollars, as well as medicine, telephones, laptops and a South African passport in the Afgooye corridor, northwest of Mogadishu on 7 June 2011. Musa Hussein was known to Mohammed as Abdullahi Dere and is believed to have been involved in funding operations for al-Shabaab. At around 11:15 p.m., the car was stopped at a security checkpoint managed by the Somalian military (SNA) in the Sarkuusta area, in southwest Mogadishu. Captain Hassan Mohamed Abukar ordered the driver to switch on the light inside the car. The driver followed the order but switched the light on and off too quickly for the soldiers to identify the people in the car, then one of the occupants opened fire. An order was given to open fire on the car. Two occupants in the car were killed and buried in Mogadishu within 24 hours. A third occupant escaped. Somalia’s National Security Agency suspected one of the dead to be Fazul after examination of the belongings; DNA tests subsequently confirmed his identity. Documents found on his body indicated he was planning a number of attacks in Britain, one of which targeted the notable Eton College.
 Passage 2:Barton Stone Alexander (September 4, 1819 – December 15, 1878) was a Union Army lieutenant colonel, engineer regiment commander and chief engineer for the defenses of Washington during the American Civil War. In recognition of his service, in 1866, he was appointed to the brevet rank of brigadier general in the regular army, to rank from March 13, 1865. He was a graduate of the U.S. Military Academy at West Point and served in the United States Army's Corps of Topographical Engineers, which at times was both a part of and separate from the United States Army Corps of Engineers. After graduating from West Point as a second lieutenant in the Class of 1842, he served in the Mexican–American War, building fortifications to protect American supply lines in the advance on Mexico City. After the end of the war, he was stationed in Washington, D.C., where he served as architect for the Scott Building and Quarters Buildings at the U.S. Soldiers' Home and took over the completion of the Smithsonian Institution Building after dissatisfaction with the pace of the first architect caused him to be dismissed.
 Passage 3:In 1991, Courau was nominated for a César, for Most Promising Actress (Meilleur espoir féminin), and won a European Film Award for Best Actress, both for the film Le petit criminel (1990). She then appeared in Dusty Hughes' A Slip of the Tongue opposite John Malkovich on the stage, and in Vincent Ward's Map of the Human Heart. In 1995, she won the Prix Suzanne Bianchetti at the SACD Awards. She was nominated again for a César twice in 1996 for Best Supporting Actress (Meilleur second rôle féminin) and Most Promising Actress (Meilleur espoir féminin) both for the film Élisa. In 1998 she was named as one of European cinema's "Shooting Stars" by European Film Promotion and in 2000 she won the Prix Romy Schneider. She was also created a Dame of the Ordre des Arts et des Lettres of France on 7 February 2007.

[EX Q]: Question: How old was Emmylou Harris when Tony Brown left her band? Passage 1:After a short period in Scotland, Foster returned to English football with Doncaster Rovers where his opportunities were limited, though he had a spell with Ilkeston Town on loan. In 2001, he signed for Forest Green Rovers in the Conference National. He made well over 100 appearances for the club and had a spell as captain. He also appeared for Forest Green in the 2001 FA Trophy final at Villa Park but was on the losing side in a 1-0 defeat to Canvey Island. He was highly regarded amongst the supporters at The Lawn and many were sad to see him leave when he departed for Halifax Town in 2004. He made just under 100 league appearances for Halifax at The Shay before a move in 2007 to Oxford United.
 Passage 2:Born in 1915, Margaret Esse Danner came of age in Chicago during the Great Migration. Sources place her birth in Pryorsburg, Kentucky, in 1915, although she adamantly claimed Chicago as her birthplace. In eighth grade, she won first prize in a school contest for "The Violin", a poem describing Stradivarius and Guarnerius violins. Danner's college education included courses at Loyola University, Northwestern University, YMCA College, and the newly founded Roosevelt College. Perhaps equally significant was her education in the African-American cultural community of Chicago's South Side, which in the 1930s and 1940s harbored grassroots cultural institutions and informal circles devoted to politics, education, art and literature and often tied to the Communist Popular Front. Although Danner stayed detached from Communism and would eventually oppose all radical politics, she participated in various South Side groups, including Inez Cunningham Stark's poetry workshop at the South Side Community Art Center, along with Gwendolyn Brooks and Margaret Goss Burroughs, her "sometime friends (and rivals)." In 1946, Danner founded Art Associates to gather and promote Chicago's black writers and poets. She counted as friends the poet and critic Edward Bland, as well as Hoyt Fuller, who would head the revived Negro Digest (later Black World) beginning in 1951.
 Passage 3:Following stints with the Dixie Melody Boys and Trav'lers Quartets, he joined J. D. Sumner and the Stamps Quartet in 1966. In 1972, he traveled briefly with the Blackwood Brothers, thereafter joining the Oak Ridge Boys as a member of The Mighty Oaks Band. Brown also played piano for Elvis Presley. He toured with the TCB Band for much of Presley's final two years and was a part of the 1976 "Jungle Room" recording sessions at Graceland. In 1979, he joined Emmylou Harris's backing band, the Hot Band, taking over for former Presley sideman Glen D. Hardin. Brown stayed with Harris until 1981. Later, he became a session musician in Nashville and toured with acts such as Rosanne Cash.
