Question: In 1991 Threlfall played against a university team from which country? Passage 1:Threfall played for Cumberland in 1987, making a single appearance in the Minor Counties Championship against Cambridgeshire and a single appearance in the MCCA Knockout Trophy against Cheshire. In 1988, Threfall played Second XI cricket for Sussex, with him also making his first-class debut for the county in that season against Somerset at the Recreation Ground, Bath. He played regularly for the Sussex Second XI, but would only make two further first-class appearances for the county, against the touring Sri Lankans in 1990 and Cambridge University in 1991. He never batted in his three first-class appearances, but with the ball he took 7 wickets at an average of 18.57, with best figures of 3/45. He also made a single List A appearance for the county against the touring Zimbabweans in 1990. He ended Sussex's innings of 233/8 unbeaten on 17, while in the Zimbabweans innings he took figures of 3/40 from 10 overs, with Sussex winning by 95 runs. He continued to play for the Sussex Second XI until 1994.
 Passage 2:American singer and songwriter Mary J. Blige began her career as a backing vocalist for Uptown Records in the early 1990s. She has released 13 studio albums, eight of which have individually achieved worldwide multi-platinum status. The Queen of Hip-Hop Soul and Queen of R&B (publications often refer to her as both honorific titles), Mary J. Blige is uniquely credited as the first singer to release an album singing over hip-hop beats, which created the genre "hip hop soul" which fuses elements of soul, R&B and gospel style vocals over hip hop beats. Blige's genre-changing sound, in many ways, changed and shaped the sound for modern day R&B and blue-eyed soul artists. In September 1999, Rolling Stone bestowed her first album, What's the 411? (1992), as "genre-creating". Her discography consists of 14 top 10 Billboard 200 studio albums, two live albums, two remix albums and over eighty singles—including more than 20 as a featured artist. In 2009, Billboard magazine ranked Blige as the most successful female R&B/hip-hop artist of the past 25 years. In March 2017, Billboard magazine ranked her 2006 song "Be Without You" as the most successful R&B/hip-hop song of all time, as it spent an unparalleled 75 weeks on the Hot R&B/Hip-Hop Songs chart, 15 of those weeks at number one. In 2011, VH1 ranked Blige as the 80th greatest artist of all time. Moreover, she was ranked 100th on the list of "100 Greatest Singers of All Time" by Rolling Stone magazine. In 2012, VH1 ranked Blige ninth among "The 100 Greatest Woman in Music" listing.
 Passage 3:While born in the United States, Pittman moved with his mother to Scotland after his parents divorced when he was two years old. He is a Scottish-American dual-citizen. He played for Broxburn Athletic as a youth player. In 1986, he began his professional career with East Fife F.C. before moving to Shrewsbury Town F.C. on March 3, 1989. In October 1987, Pittman had an unsuccessful trial with the Cleveland Force of Major Indoor Soccer League. On March 29, 1990, Pittman signed with the Fort Lauderdale Strikers of the American Professional Soccer League. He was both a first team All Star and the 1990 Rookie of the Year. On August 29, 1990, he signed with the Wichita Wings of the Major Indoor Soccer League. In 1991, he returned to the Strikers. The team released him in August 1991 after an accumulation of yellow and red cards kept him out of seven games during the season. After being ejected in a late season game, Pittman entered the stands to chase a spectator leading to league officials suspending him for the first two games of the play offs. He then rejoined the Wichita Wings for the upcoming MISL season. Despite being released by the Strikers in August 1991, the team re-signed Pittman at the end of April 1992. When the APSL season ended in August, the Strikers loaned Pittman Dundee F.C.. When Pittman's contract with the Strikers ran out, he then signed with Dundee as a free agent. In September 1994, he moved to Partick Thistle F.C. Whilst at Partick Thistle, where Pittman enjoyed arguably the most successful period of his career, he became somewhat of a cult hero after regularly performing his "Marine Drive" free-kick. After lining up a direct free-kick, Pittman would stand on one foot and offer up a military style salute to the Thistle fans, before unleashing a shot towards goal. He only managed to score once in this fashion, in a closed-door friendly match against Berwick Rangers. His career with Partick ended when he accumulated three red cards in quick succession after confronting referees following an end of season match. This led to an eight-game ban. In 1996, he signed with the Tampa Bay Mutiny of Major League Soccer. In July 1996, he scored the winning goal for the East during the 1996 All-Star Game. He also toured China as a guest player for San Jose Clash in 1996. On January 9, 1997, the Mutiny traded Pittman to the Kansas City Wizards in exchange for Alan Prampin and the Wizards' third round pick in the 1997 MLS Supplemental Draft. The Wizards waived him on November 17, 1997 and he returned to Scotland where he joined Clydebank F.C. At some point he transferred to Stenhousemuir F.C. where he played three games at the start of the 2000-2001 season. In November 2000, he transferred to Linlithgow Rose F.C. He finished his career at Pumpherston F.C.

Question: What city did Stevens complete a Ph.D. in? Passage 1:The siblings were born in New Haven, Connecticut, and moved to Downey, California, in 1963. Richard took piano lessons as a child, progressing to California State University, Long Beach, while Karen learned the drums. They first performed together as a duo in 1965 and formed the jazz-oriented Richard Carpenter Trio followed by the middle-of-the-road group Spectrum. Signing as Carpenters to A&M Records in 1969, they achieved major success the following year with the hit singles "(They Long to Be) Close to You" and "We've Only Just Begun". Subsequently, the duo's brand of melodic pop produced a record-breaking run of hit recordings on the American Top 40 and Adult Contemporary charts, and they became leading sellers in the soft rock, easy listening and adult contemporary music genres. The Carpenters had three number-one singles and five number-two singles on the Billboard Hot 100 and fifteen number-one hits on the Adult Contemporary chart, in addition to twelve top-10 singles. They have sold more than 90 million records worldwide, making them one of the best-selling music artists of all time. The duo toured continually during the 1970s, which put them under increased strain; Richard took a year off in 1979 after he had become addicted to Quaaludes, while Karen suffered from anorexia nervosa.
 Passage 2:In 1980, Stevens joined the Army under their split option training program and conducted basic training at Fort Dix, New Jersey and advanced individual training at Fort Sam Houston, Texas. While engaged in his military service, Stevens entered the University of Southern Maine in the Computer Science program in 1981. However, an enthusiastic professor (John Ricci) converted him to the study of Chemistry. He spent two summers working as an intern at the Brookhaven National Laboratory in Long Island with Professor Ricci, and Drs. Thomas Koetzle and Dick McMullan, where he first learned how to determine the molecular structure of compounds by X-ray and neutron diffraction. While there he also met a University of Southern California research team led by Dr. Robert Bau; after he obtained a Bachelor of Science degree in Chemistry at USM, he entered the University of Southern California in pursuit of a Doctor of Philosophy degree in Chemistry working with Professor Robert Bau and Nobel Laureate Professor, George Olah. He completed his Ph.D. in 26 months, graduating in 1988.
 Passage 3:The 1966 NASCAR season opened at Augusta Speedway on November 14, 1965, with Richard Petty winning the season opening event in a 1965 Plymouth. NASCAR then ventured to Riverside International Raceway where Dan Gurney took the checkered flag in a 1965 Ford. After the January 23rd Riverside event, the drivers and teams traveled to Daytona International Speedway in Florida for the 1966 Daytona 500. Paul Goldsmith and Early Balmer took the qualifying events, while Richard Petty notched his first and only Daytona 500 pole position. Petty came from two laps down during the competition to win by more than a full lap when the race was halted 2 laps shy of scheduled event due to thunderstorms. In March Paul Goldsmith won at Rockingham Speedway, Dick Hutcherson at Bristol, and Jim Hurtubise captured the checkered flag at Atlanta Motor Speedway. Hutcherson's victory at Bristol was by more than 4 laps over the closest competitor, Paul Lewis, when crashes and attrition left only seven cars of the 38 starters running at the end of the Southeastern 500 (now known as Food City 500). On April 3, Pearson finally found his way to victory lane in the first of four consecutive victories at Hickory Motor Speedway. He followed up with wins at Columbia Speedway, Greenville, and Winston-Salem, before Jim Paschal broke his streak at North Wilksboro and repeated at Martinsville Speedway. On May 7, Richard Petty started a string of three consecutive wins at Darlington Raceway, Hampton, and Macon. After Ford's announcement of their boycott of NASCAR on April 7, only 2.500 fans attend the May 13th event in which Darel Dieringer captures the win at Monroe in a contest.

Passage 1:In 2004, Gorka became an adjunct to the faculty of the new US initiative for the Program for Terrorism and Security Studies (PTSS), a Defense Department-funded program based in the George C. Marshall European Center for Security Studies in Garmisch-Partenkirchen, Germany. At the same time Gorka became an adjunct to USSOCOM's Joint Special Operations University, MacDill Air Force Base. He and his family relocated to the United States in 2008. He was hired as administrative dean at the National Defense University, Fort McNair, Washington D.C. Two years later, he began to lecture part-time for the ASD(SO/LIC)-funded Masters Program in Irregular Warfare and Counterterrorism as part of the Combating Terrorism Fellowship Program but remained in a largely administrative role. Between 2009 and 2011 Gorka wrote for the Hudson Institute of New York (now Gatestone Institute). Between 2011 and 2013, Gorka was an adjunct faculty member at Georgetown University's McCourt School of Public Policy. In 2014 Gorka assumed the privately endowed Major General Matthew C. Horner Distinguished Chair of Military Theory at the Marine Corps University Foundation. From 2014 to 2016, Gorka was an editor for national security affairs for Breitbart News, where he worked for Steve Bannon. In August 2016, he joined The Institute of World Politics, a private institution, on a full-time basis as Professor of Strategy and Irregular Warfare and Vice President for National Security Support. He is on the advisory board of the Council for Emerging National Security Affairs (CENSA).
 Passage 2:Thordön (later spelled Tordön) was laid up in reserve in 1868 and 1869. She was rearmed with 240-millimeter M/69 guns (serial numbers 5 and 6) in 1872, but was laid up again from 1874 to 1882. The ship ran aground and sank on Lilla Rimö Island, off Norrköping, on 23 July 1883. She was salvaged on 4 August and managed to proceed under her own power to Karlskrona Naval Dockyard for repairs. The subsequent court-martial ordered the ship's captain to pay for the costs of the salvage and repairs, despite a misplaced buoy that caused the ship to ground. She was recommissioned in 1885 and 1888–89 before being placed back in reserve. Tordön was reconstructed in 1903–05; she received a pair of new Bofors M/94 guns that were given elevation limits of −7° and +15°. The ship also received eight 57-millimeter guns and new boilers. She was reactivated during World War I and assigned to the Gothenburg local defense flotilla in company with her sister Tirfing. Both ships were decommissioned in 1922 and sold the following year. Their new owner converted them into barges and used them in Stockholm harbor.
 Passage 3:The Sher-e-Bangla National Cricket Stadium, formerly known as the Mirpur Stadium due its location in the city's locality of Mirpur, is a sports ground in Dhaka, Bangladesh that has hosted international cricket matches along with provincial games. It is named after AK Fazlul Huq, one of the renowned leaders among the natives who was accorded the title Sher-e-Bangla ("tiger of Bengal"). The venue was taken over by the Bangladesh Cricket Board in 2004, replacing the Bangabandhu National Stadium as the home of both the men's and women's national teams. It has a capacity of 25,000 spectators for international matches. The first Test at this venue took place in 2007, between Bangladesh and India, and the first One Day International (ODI) match was held between Bangladesh and Zimbabwe in 2006.
