premise: Several people are looking up at a man on a telephone pole. hypothesis: People are looking at a man on a telephone pole who climbed up there so the Graboids didn't get him.
neutral: A person could be up a telephone pole for a number of reasons, not just because they are afraid of whatever "Graboids" are. It is even possible to get on a telephone pole without having climbed it- they could have been carried there by a cheery-picker or other sort of crane.
