context: It is probably the case that Greg is a rhino. It is highly likely that Julius is a frog. It is unlikely that Mary left the milk. We believe that if either Greg is a rhino, or Julius is a frog, then John got the apple. Chances are slight that if Mary left the milk, and Greg is a rhino, then Brian is gray. It is impossible that if Julius is a frog, or Mary left the milk, then Lily is white.
hypothesis: It is probable that lily is white, or Greg is a rhino.
valid_hypothesis: It is probable that lily is white, or Greg is a rhino.
invalid_hypothesis: We doubt that lily is white, or Greg is a rhino.
hypothesis_assertion: Lily is white, or Greg is a rhino.
