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.

Question: How many soldiers did Britain send to World War I the year Roebuck arrived on the Western Front? Passage:As a boy, Roebuck worked as a trammer and after being sentenced to one month's imprisonment for stealing a watch in 1904, he enlisted in the York and Lancaster Regiment. Over the next seven years, he was stationed in India and Ireland and was promoted to lance corporal, but was demoted back to private in 1910 for "misconduct". He married in 1908 and had two children. Roebuck was discharged into the reserves in 1912 and likely returned to work as a miner prior to becoming a professional footballer in 1913. After Britain's entry into the First World War in August 1914, he was called up by the York and Lancaster Regiment and arrived on the Western Front in September 1914. On 18 October 1914, Roebuck recorded as "presumed dead" after an attack near Beaucamps-Ligny during the Race to the Sea. His death was confirmed by two comrades in January 1915. Roebuck is commemorated on the Ploegsteert Memorial to the Missing.
