premise: a man is wakeboarding in a lake
hypothesis: the man is getting wet
explanation_1: Lakes are full of water, and people who do stuff in them generally end up getting wet unless they're in a boat shielding them from the water.  Wakeboards are not boats.  Nor do they have a water-repellent field with which to keep the user dry.
