Question: How long did Luigi Chinetti drive in the race? Passage:Sommer was born in Mouzon, in the Ardennes département of France, into a wealthy Sedan carpet-making family. His father, Roger Sommer, broke the Wright Brothers' record for the longest flight in 1909. It was not until 1931 that Raymond started to display daredevil tendencies of his own, entering motor races in a privateer Chrysler Imperial. The following year, he won the 24 Hours of Le Mans race, despite having to drive over 20 hours solo after his teammate, Luigi Chinetti, retired ill. During the 1930s, Sommer was to dominate the French endurance classic, winning again in 1933 driving an Alfa Romeo alongside Tazio Nuvolari. He also led every race until 1938, only to suffer a mechanical failure, once when 12 laps in the lead. Sommer traveled to Long Island, New York, to compete in the 1936 Vanderbilt Cup where he finished fourth behind the winner, Nuvolari.

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.
