context: There is little chance that Emily is a wolf. It is probably the case that Greg is yellow. It is impossible that Bill went to the hallway. Chances are about even that if either Bill went to the hallway, or Emily is a wolf, then Julius is white. It is almost certain that if Greg is yellow, or Emily is a wolf, then Lily is a rhino. It is unlikely that if Emily is a wolf, and Bill went to the hallway, then Fred is in the school.
hypothesis: There is almost no chance that lily is a rhino, or Emily is a wolf.
valid_hypothesis: It is likely that lily is a rhino, or Emily is a wolf.
invalid_hypothesis: There is almost no chance that lily is a rhino, or Emily is a wolf.
hypothesis_assertion: Lily is a rhino, or Emily is a wolf.
