[EX Q]: Question: Where did Dudow work with Leopold Jessner? Passage 1:Dudow was born in Zaribrod, Bulgaria (today Dimitrovgrad, Serbia). In 1922, he emigrated to Berlin with the intention of becoming an architect. He gave up this plan and began studying theatre in 1923, first under Emmanuel Reicher, and then, from 1925 to 1926, as a theatre studies student under Max Herrmann at the university. He worked with Leopold Jessner and Jürgen Fehling, served as a chorus member under Erwin Piscator, and was a director's assistant to Fritz Lang on the production of Metropolis. During this time, Dudow also ran a bookstore with his wife and worked as a foreign correspondent for a Bulgarian newspaper. In 1929, he visited the Soviet Union, where he met Vladimir Mayakovsky and Sergei Eisenstein in Moscow and eventually, Bertolt Brecht. After his return from the USSR, Dudow directed Brecht's theatrical piece, The Decision (Die Massnahme), and began his film directing career. He was commissioned by the left-wing, Soviet-German production company Prometheus-Film to direct a short film, Wie der Berliner Arbeiter wohnt (1929), as part of the documentary series Wie lebt der Berliner Arbeiter? Dudow's first feature, Kuhle Wampe (To Whom Does the World Belong?, 1932) was a collaboration with Brecht (who provided the script and helped finance the project), Hanns Eisler, and Ernst Ottwalt. It was banned because it was perceived as being politically subversive. 
 Passage 2:Boulding maintained his links with football and trained with Doncaster Rovers, and in 1998 he joined non-league Hallam near his home in Sheffield. His form at Hallam attracted the interest of a number of league clubs, and Boulding was offered a trial by Mansfield Town. He was given a contract by the Division Three side and turned professional in 1999, which brought an end to his tennis career. He made his debut with Mansfield in a League Cup game against Nottingham Forest on 11 August 1999 as a late substitute for Gary Tallon, before his first league game came three days later against Cheltenham Town. He had to wait until his 12th game as a professional to register his first goal when he scored in a 2–1 victory over Shrewsbury Town on 23 October. He eventually finished his first season with six goals with Mansfield coming 17th but 17 points above Carlisle United, the only side to be relegated out of The Football League.
 Passage 3:Jones was selected by the Dallas Cowboys in the first round (24th overall) of the 1992 NFL Draft, becoming the first player from East Carolina University to be drafted that high. The team moved Ken Norton Jr. to outside linebacker, allowing him to become the second rookie (Eugene Lockhart) in Cowboys history to start at middle linebacker, and the second rookie (Lee Roy Jordan) linebacker in franchise history to start in a season-opener. He helped the Cowboys establish the top defense in the league in 1992, was named NFC rookie of the year and was selected to the NFL All-rookie team. He started 13 out of 15 games, posting 108 tackles (second on the team), one sack, 2 tackles for loss, 4 quarterback pressures, one pass defensed and one fumble recovery. He had 16 tackles against both the Philadelphia Eagles and Kansas City Chiefs.

[EX Q]: Question: How many sales are required to get the certification from the RIAA that Enjoy Yourself recieved in 1989? Passage 1:For 1970, Matra insisted on using their own V12 engines, while Tyrrell and Stewart wanted to continue with the Cosworth and maintain their connection to Ford, which conflicted with Matra's recent connections to Chrysler. Tyrrell decided to build his own car and in the interim bought a chassis from March Engineering; Stewart took the March 701-Cosworth to wins at the Daily Mail Race of Champions and Jarama, but development on the car stalled and it was soon overcome by the Lotus team's new 72. The new Tyrrell 001-Cosworth, appeared in August and suffered problems but showed promise. Tyrrell continued to be sponsored by French fuel company Elf, and Stewart raced in a car painted French Racing Blue for many years. Stewart also continued to race sporadically in Formula Two, winning at Crystal Palace and placing at Thruxton. A projected Le Mans appearance, to co-drive the 4.5 litre Porsche 917K with Steve McQueen, did not come off, due to McQueen's inability to get insurance. He also had a one-off race in Can-Am, in the revolutionary Chaparral 2J. Stewart qualified third, in what was the car's first outing, but brake failure ended his race.
 Passage 2:"Enjoy Yourself" is a song recorded by The Jacksons and released as a single in 1976. Featuring Michael and Jackie Jackson on lead vocals, it was the first non-Motown single for the group since they departed from the label earlier that year. The song peaked at #6 on the Billboard Hot 100 chart on February 19, 1977. On other US charts, "Enjoy Yourself" peaked at #2 on the Hot Soul Singles chart, and #33 on the National Disco Action Top 40 chart. On February 14, 1989, it became the group's first single to be certified Platinum by the RIAA. It was also the group's first song to feature new member Randy Jackson, who replaced Jermaine when he decided to stay at Motown after his brothers left. The song is sampled on the track "Let's Have a Party" by the Backstreet Boys, which appears on their 1996 self-titled debut album. The song is credited to Philadelphia songwriters/producers Gamble and Huff; however, a session musician from Gamble and Huff’s in-house band recalled that the late guitarist T.J. Tindall wrote the riff that was the initial spark for the song.
 Passage 3:Williams quickly reloaded the team with top talent, bringing in recruits like Brandan Wright, Ty Lawson, Wayne Ellington and Deon Thompson. The 2006–07 team tied as ACC regular season champions, earning the tiebreak over the Virginia Cavaliers. With the #1 seed, the Tar Heels won the ACC Tournament. After earning a #1 seed in the East Region in the 2007 NCAA Tournament, Williams' team won its first-round game against Eastern Kentucky Colonels 86–65 and its second against Michigan State 81–67. North Carolina then defeated the USC Trojans 74–64 to advance to the Elite Eight. On March 24, 2007, North Carolina fell to the Georgetown Hoyas in overtime in the East Regional, ending its post-season run. Following the 2006–2007 season, Williams announced on July 18, 2007, that he had vertigo, a condition that occasionally forces him to sit down suddenly during games.

[EX Q]: Question: How old was Steven Schumacher the year that Michael Symes signed for the League One side with him? Passage 1:Crewe manager Dario Gradi decided not to offer a contract to Symes, who instead spent a period on trial at Bradford City, which included an 8–1 pre-season friendly win over Farsley Celtic. He signed for the League One side in July 2004 with fellow former Everton trainee Steven Schumacher, with whom he lived during his spell at Bradford. Symes made his Bradford debut in a 2–1 defeat at Hartlepool United on the opening day of the 2004–05 season. Three days later he missed a late penalty which would have secured Bradford victory over Peterborough United in a game in which Symes was also booked. Symes was dropped from the first team after Bradford signed Dele Adebola. When Bradford were allowed special dispensation to sign Neil Roberts, Bradford tried to give Symes a loan transfer to Darlington but the deal was blocked by the Football League. The following month, Symes scored his first goals for Bradford when he came off the bench at half-time to score twice in a 3–1 victory over Sheffield Wednesday on 23 October 2004. They were the only goals he scored that season from just 15 games.
 Passage 2:Originally a winger, Baker joined Plymouth Argyle as a teenager in the early 1950s. He made his first team debut in October 1954, but appeared sporadically over the next three years, as he developed his game playing for the club's reserve team in the Plymouth & District, Devon Wednesday, and Football Combination Leagues. He became a first team regular in 1958, and played an important part in the club's Third Division title campaign a year later. After that success, Baker sustained a knee injury which eventually brought his career at Home Park to an end. He scored 17 goals in all competitions for the club and made 83 appearances. He joined Shrewsbury Town in 1961, who were under the management of Arthur Rowley. He played in the match where Rowley broke Dixie Dean's record for most goals scored in the Football League. After 5 goals in 52 appearances, Baker returned to South Wales in 1962 to play for Barry Town, where he finished his career playing in the Southern League.
 Passage 3:In 1982, at age 22, he became the TV and radio voice of the NBA's Kansas City Kings (now the Sacramento Kings). He then was a basketball announcer for his alma mater, the University of Kansas, for one year, then went on to call games for the NFL's Kansas City Chiefs from 1985–93 after several years hosting and producing surrounding pre-game and post-game programming (coincidentally, current Packers play-by-play voice Wayne Larrivee left the Chiefs position open when he began a thirteen-year run as the voice of the Chicago Bears). Harlan also split time with the University of Missouri (1986–89) calling football and basketball games, and worked as the play-by-play voice of the NBA's Minnesota Timberwolves for nine seasons (1989–98). On the network level, Harlan called NFL football for NBC in 1991, college football for ESPN in 1992–93, NFL for Fox from 1994–97, and joined Turner Sports in 1996 to cover NBA playoff games (he would begin calling games throughout the entire season in 1997, which he continues to do to this day). He began working for CBS in 1998.
