 Passage 3:Robertson moved to Central States Wrestling, where he won the majority of his titles. On October 22, 1981, he won the NWA Central States Television Championship with a victory over Gene Lewis. He lost the belt to Oliver Humperdink later that year but soon regained it in a rematch. On February 18, 1982, however, he dropped the belt back to Lewis. This allowed Robertson to focus on the NWA Central States Tag Team Championship, which he won a total of five times. His first reign came in October 1981 when he teamed with Rufus R. Jones to defeat Buzz Tyler and James J. Dillon. His next reign came in March 1982 when he teamed with Steve Regal to win the belts from Roger Kirby and Jerry Valiant. The title changed hands twice more that month, as Kirby and Valiant quickly regained the title only to drop it back to Robertson and Regal. Two months later, Kirby and Valiant won the belts back again. Robertson found a new partner, however, and won the championship by teaming with Hercules Hernandez in August. The reign lasted less than a month, but Robertson and Hernandez held the belts one final time after another victory in September 1982. The following year, Robertson's main success came as a singles wrestler. On February 10, 1983, he won the NWA Central States Heavyweight Championship with a victory over Manny Fernandez. He lost the belt to Bob Brown two months later but regained it in a rematch the following week. Robertson's final title reign ended when he dropped the title to Race on June 2, 1983.

Example Input: 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.
