Question: Kansas City Live Stock Exchange was the HQ of a yard which closed when?
Context: The Kansas City Stockyards in the West Bottoms west of downtown Kansas City, Missouri flourished from 1871 until closing in 1991. The Golden Ox was a steakhouse restaurant located in the Kansas City Live Stock Exchange building in the West Bottoms area of Kansas City, Missouri.  Founded in 1949, the Golden Ox was the birthplace of the Kansas City strip steak.  The Golden Ox was often regarded as the oldest steakhouse in Kansas City, because while Jess & Jim's Steakhouse opened more than a decade earlier in 1938, the Martin City area where Jess & Jim's is located was not annexed by Kansas City until 1963.  The original Golden Ox location closed permanently following dinner on December 20, 2014, but new owners have leased the space and will reopen the Golden Ox in a renovated portion of the original space in Spring 2016. The Kansas City Live Stock Exchange was the headquarters of the Kansas City Stockyards.  It is located at 1600 Gennesse in Kansas City, Missouri, in the West Bottoms.
