context: There is almost no chance that Greg is a lion. Chances are slight that Lily is a frog. It is likely that Brian is a swan. It is probably not the case that if either Lily is a frog, or Greg is a lion, then Bernhard is green. We believe that if either Lily is a frog, or Brian is a swan, then John moved to the garden. We doubt that if Lily is a frog, or Greg is a lion, then Bill went to the office.
