context: It is probably the case that Bernhard is a lion. It is highly unlikely that Julie is in the office. There is little chance that Emily is a wolf. It is highly unlikely that if either Emily is a wolf, or Julie is in the office, then Lily is a rhino. It is improbable that if Bernhard is a lion, or Julie is in the office, then Julius is gray. We doubt that if Bernhard is a lion, and Emily is a wolf, then John went to the bedroom.
hypothesis: Chances are slight that either Julius is gray, or John went to the bedroom.
valid_hypothesis: Chances are slight that either Julius is gray, or John went to the bedroom.
invalid_hypothesis: There is a better than even chance that either Julius is gray, or John went to the bedroom.
