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 1615 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 200910. 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 199394 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 45 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 5527 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.
