All skateboarders are not wearing a blue hat and goggles. Just because he is a skateboarder doesn't imply he grinds his skateboard down a ramp.


Consider the statement "A guy on a skateboard does a trick on a ramp while others watch on the other side of the ramp.". Based on this "A man in a blue hat and goggles grinds his skateboard down a ramp." a true statement? Yes, no, or I don't know?
