Input: Consider Input: Question: In what year did the Kansas City Kings become the Sacramento Kings? Passage: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.

Input: Consider Input: Question: How tall is the player that was brought back to Boston in a February 24, 2005 trade that involved Payton? Passage:Prior to the 2004–05 season, the Lakers traded Payton and Rick Fox to the Boston Celtics for center Chris Mihm, small forward Jumaine Jones and point guard Chucky Atkins. While Payton expressed displeasure with the trade, he ultimately did report to Boston and began the 2004–05 season as the Celtics' starting point guard. On February 24, 2005 Payton was traded to the Atlanta Hawks in a deal that brought former Celtic Antoine Walker back to Boston. The Hawks then waived Payton immediately following the trade, and he returned a week later to Boston as a free agent. Payton started all 77 games he played for Boston and averaged 11.3 points per game and 6.1 assists as the Celtics won the Atlantic Division before losing in the first round to the Indiana Pacers.

Input: Consider Input: Question: What is the age difference between the two children acting in the play? Passage:The Bedrock Community Players is mounting A Christmas Carol, and all of the town's citizens are either planning to attend or be involved in the production: Barney Rubble is playing Bob Cragit, with Betty as Mrs. Cragit and his son Bamm-Bamm as Tiny Tim; Mr. Slate is Jacob Marbley; Wilma Flintstone is serving as the stage manager, while her daughter Pebbles plays Martha Cragit; even Dino has a role, playing the Cragit's family pet. It is Fred, though, who has landed the leading role of Ebonezer Scrooge. Unfortunately, he has let his role go to his head, thinking himself a star and spending all of his time rehearsing his lines rather than focusing on his job or family. On Christmas Eve, in his rush to get to work, Fred forgets that he must take Pebbles to "cave care", and later to pick her up from cave care. When Fred arrives at the theater, he discovers a furious Wilma, who breaks down in tears as she tells Fred about his mistake.
