context: We believe that Julius is white. Chances are about even that Mary moved to the office. We believe that Emily is a cat. It is probably the case that if Mary moved to the office, and Julius is white, then Bernhard is a lion. It is almost certain that if either Mary moved to the office, or Emily is a cat, then Brian is yellow. It is highly unlikely that if Emily is a cat, or Julius is white, then John went to the bedroom.
hypothesis: There is a better than even chance that john went to the bedroom, and Brian is yellow.
valid_hypothesis: There is almost no chance that john went to the bedroom, and Brian is yellow.
invalid_hypothesis: There is a better than even chance that john went to the bedroom, and Brian is yellow.
hypothesis_assertion: John went to the bedroom, and Brian is yellow.
