context: We believe that Greg is a frog. There is little chance that Lily is yellow. It is highly likely that Jessica is a mouse. It is likely that if Jessica is a mouse, and Greg is a frog, then Daniel left the apple. There is a very good chance that if Jessica is a mouse, or Lily is yellow, then John discarded the apple. Chances are slight that if Jessica is a mouse, or Lily is yellow, then Mary went to the bedroom.
hypothesis: It is probably the case that either Greg is a frog, or Mary went to the bedroom.
