These sentence don't seem contradictory to me as I have seen a video of someone backflipping into a lake while riding a skateboard.  I guess it is difficult to do a backflip on a skateboard and not many people try doing this into a lake.


Consider the staetement "A boy back flipping into a lake in midair.". Based on this statement, is "A boy is riding a skateboard." a true statement? Yes/no/unknown
