context: It is impossible that Bernhard is a frog. There is little chance that Lily is a swan. There is almost no chance that Greg is a lion. It is certain that if either Greg is a lion, or Lily is a swan, then Daniel took the milk. It is highly unlikely that if either Bernhard is a frog, or Lily is a swan, then Brian is a frog. It is probably the case that if Bernhard is a frog, and Greg is a lion, then John picked up the apple.
