Task: Question Generation
Input (English): Man o' War -- Man o' War was not entered in the 1920 Kentucky Derby because his owner, Samuel Riddle, did not believe in racing at the distance of 10 furlongs so early in a young horse's career. Instead, Man o' War made his three-year-old debut in the Preakness Stakes where he defeated Upset by ​1 ⁄ lengths. Man o' War later won the Belmont Stakes by 20 lengths while setting a world record. Throughout the summer and fall, he continued to dominate his fellow three-year-olds, setting multiple records while conceding large amounts of weight to his rivals. The only time he faced older horses was in the final race of his career in a match race against Sir Barton, who had won what would later be known as the American Triple Crown in 1919. Man o' War won easily by seven lengths in the first horserace to be filmed in its entirety.
Output (English): did man of war win the kentucky derby
