Premise: The 2009 NASCAR Banking 500 only from Bank of America was a NASCAR Sprint Cup Series stock car race held on October 17, 2009 at Lowe's Motor Speedway in Concord, North Carolina. The race was the thirty-first of the 2009 NASCAR Sprint Cup season, the fifth of the Chase for the Sprint Cup, and the only race scheduled at night during the ten-race Chase for the Sprint Cup that ended the season.
Hypothesis: the Chase for the Sprint Cup was during the day.
