context: There is a very good chance that Greg is yellow. Chances are slight that Bill dropped the milk. It is probably the case that Mary went to the office. We doubt that if Mary went to the office, and Bill dropped the milk, then Brian is green. It is probable that if Greg is yellow, and Bill dropped the milk, then Bernhard is a frog. It is likely that if either Greg is yellow, or Mary went to the office, then Lily is a lion.
hypothesis: It is highly unlikely that bernhard is a frog, or Brian is green.
valid_hypothesis: It is highly unlikely that bernhard is a frog, or Brian is green.
invalid_hypothesis: We believe that bernhard is a frog, or Brian is green.
