[EX Q]: Question: How many years had Dilbert been a televised cartoon by the year that West had a cameo on it? Passage 1:West's first major roles were on Doug and The Ren & Stimpy Show, which were two of the first three Nicktoons on Nickelodeon (the other being Rugrats). Over his career, West has been the voice talent for close to 120 different characters including some of the most iconic animated figures in television history. He has become one of the few voice actors who can impersonate Mel Blanc in his prime, including characterizations of Bugs Bunny and Daffy Duck, the voice Arthur Q. Bryan used for Elmer Fudd, as well as other characters from Warner Bros. cartoons. In 1998, Entertainment Weekly described West as "the new Mel Blanc" and noted his ability to mimic well-known voices, though he would rather develop original voices. West's favorite characters are Philip J. Fry and Stimpy, both of which he originated. West has been very outspoken over his displeasure about the influx of movie star actors providing voice-over for films and major shows. West has stated that he did not like the Disney version of Doug and that he "couldn't watch" the show. West was the voice of the show's namesake, Geeker, throughout Project Geekers 13-episode run. West was the voice of Zim in the original pilot for Invader Zim. Richard Steven Horvitz was chosen for the series role because West's voice was too recognizable, according to creator Jhonen Vasquez during DVD commentary. West is the voice of "Red" in numerous M&M commercials as well as the 3-D movie I Lost my M in Vegas, currently playing at M&M's World in Las Vegas, Nevada. He also voices a number of minor characters in the series . He voiced the character Moobeard in Moobeard the Cow Pirate, a short animation featured on Random! Cartoons and reprises his role as Elmer Fudd in Cartoon Network's series The Looney Tunes Show. In 1999, he also had a cameo in the Emmy Award-winning cartoon Dilbert.

[EX Q]: Question: Who is the head of the National Basketball Association? Passage 1:The Hoyas′ previous season had been a disappointing one in which the relatively young and experienced Georgetown team had fallen from a Top Ten ranking in early January 2009 to a 16–15 finish in March that ended with the loss of 12 out of 16 games and first-round exits from both the 2009 Big East Tournament and the 2009 National Invitation Tournament. The Hoyas had lost starting forward DaJuan Summers after the end of the season when he chose to forego his senior year of college and enter the 2009 National Basketball Association draft, as well as starting guard Jessie Sapp, who graduated, and reserve guard/forward Omar Wattad, who transferred. But with freshman forwards Jerrelle Benimon and Hollis Thompson joining the team and sophomore starting center Greg Monroe, junior reserve center Henry Sims, junior starting guards Austin Freeman and Chris Wright, junior reserve forward Julian Vaughn, and sophomore reserve forward Jason Clark all returning, the Hoyas expected to bounce back in 2009–10. The preseason Associated Press Poll ranked them No. 20.
 Passage 2:Lewald was born in 1860; his aunt was Jewish novelist Fanny Lewald. Lewald became a civil servant in Prussia in 1885, and became the acting Reich Commissioner in 1903. In that role, Lewald attended the 1904 Worlds Fair (held along with the Olympic Games), where he disagreed with Kaiser Wilhelm II over whether the Deutscher Olympischer Sportbund, of which he was the President, should be politically independent. After Berlin won the right to stage the 1916 Summer Olympics (which were later cancelled due to the outbreak of World War I), Lewald encouraged the German Reich to invest in the games, arguing that it was comparable to a World Trade Exhibition. Lewald retired from government in 1923; he had been the under Secretary of State. In 1935, Lewald recommended that Pierre de Coubertin be awarded a Nobel Prize.
 Passage 3:The 1993–94 NBA season was the Spurs' 18th season in the National Basketball Association, and 27th season as a franchise. It was also their first season at the Alamodome. During the offseason, the Spurs acquired All-Star forward Dennis Rodman from the Detroit Pistons, and signed free agent Sleepy Floyd. Rodman led the league with 17.6 rebounds per game as the Spurs went on an 8-game winning streak after a 4–5 start to the season. The team would then win 13 consecutive games between January and February, and finish second in the Midwest Division with a 55–27 record. David Robinson captured the scoring title leading the league with 29.8 points per game, and was selected for the 1994 NBA All-Star Game. However, in the first round of the playoffs, Rodman became a distraction as he scuffled with head coach John Lucas as the Spurs lost to the 5th-seeded Utah Jazz in four games.

 Passage 2:The record builds on ideas explored in Pink Floyd's earlier recordings and performances, while omitting the extended instrumentals that characterised their earlier work. A concept album, its themes explore conflict, greed, time, death, and mental illness, the latter partly inspired by the deteriorating health of founding member Syd Barrett, who departed the group in 1968. The group used recording techniques such as multitrack recording, tape loops, and analogue synthesisers. Snippets from interviews with the band's road crew, as well as philosophical quotations, were also used. Engineer Alan Parsons was responsible for many sonic aspects and the recruitment of singer Clare Torry, who appears on "The Great Gig in the Sky". The sleeve, which depicts a prism spectrum, was designed by Storm Thorgerson, following keyboardist Richard Wright's request for a "simple and bold" design, representing the band's lighting and the record's themes. The album was promoted with two singles: "Money" and "Us and Them".
