premise: A man in a black shirt and black jeans and a little boy are taking a look inside a green truck's engine while it is parked in a grass field with a gas tank in front of it. hypothesis: A man and his son are trying to fix their truck.
neutral: Just because a man and a little boy are taking a look inside a green truck's engine, does not imply the little boy is the man's son, and that they are trying to fix their truck.
