premise: Breaking Up<br>Tom hated his girlfriend. He kept trying to break up with her. She never really let him. Tom eventually moved away. He ignored her completely.
hypothesis: Tom stopped all communication with his girlfriend after he moved away.
reason: It says he ignored her completely, which can be reasonably assumed to mean that he stopped communicating with her entirely after he moved away. It's difficult perhaps because it is not mentioned explicitly and requires some inference.
