context: There is a better than even chance that Jeff discarded the milk. We doubt that Brian is a swan. We believe that Julius is a frog. It is likely that if Jeff discarded the milk, and Brian is a swan, then Greg is a rhino. We doubt that if either Brian is a swan, or Julius is a frog, then John went to the hallway. It is probably not the case that if Jeff discarded the milk, and Julius is a frog, then Daniel left the apple.
