premise: A man riding a motorcycle on a dirt road passing several junk or abandoned cars on the side of the road.
hypothesis: A man is making a cross country trip on his motorcycle.
explanation_1: The man may be just going from point a to b on his motorcycle rather than on a trip.
explanation_2: We have no idea if he is making a cross country trip or not, he could be going anywhere doing anything.
explanation_3: Just because a man is riding a motorcycle does not mean he is making a cross country trip.
