premise: Robert Anthony Stoops (born September 9, 1960) is a former American college football coach. He is the former head football coach at the University of Oklahoma, a position he held from 1999 until he announced his retirement June 7, 2017. During the 2000 season, Stoops led the Sooners to an Orange Bowl victory and a national championship.
hypothesis: Robert Anthony Stoops was a head football coach at an American university until he was almost 57 years old.
reason: The statement is correct because based on the birth date and retirement date given, Stoops was a few months short of 57 years old when he retired.  I think this fooled the system because the system could not make the connection required to make this calculation.
