premise: A man wearing yellow sneakers and a black vest is on a water board and hangs onto a waterski line that appears to be towed by a boat.
hypothesis: A man on a lake is learning how to waterboard slowly.
explanation_1: Not just because a man hangs onto a waterski line doesn't mean he is learning how to waterboard
explanation_2: Just because a man hangs onto a waterski line it does not mean the man is learning how to waterboard on a lake.
explanation_3: Not all water skiing is done in a lake and there is no indication that the man is learning slowly.
