context: It is highly unlikely that Mary moved to the office. There is almost no chance that Brian is a swan. It is highly likely that Greg is a lion. It is probably not the case that if Greg is a lion, and Brian is a swan, then Daniel left the apple. It is likely that if Greg is a lion, or Mary moved to the office, then Lily is yellow. We doubt that if Greg is a lion, and Brian is a swan, then John went to the garden.
