premise: Jerick Deshun McKinnon (born May 3, 1992) is an American football running back for the Minnesota Vikings of the National Football League (NFL). He was drafted by the Vikings in the third round of the 2014 NFL Draft. He played college football at Georgia Southern.
hypothesis: McKinnon was born while Mercury was in retrograde.
reason: You would not know from the text whether or not Mercury was in retrograde in May of 1992. I'm not sure why the system would judge this as definitely incorrect.
