context: We believe that Lily is green. It is unlikely that Sandra grabbed the milk. It is highly unlikely that Brian is a rhino. There is a better than even chance that if Lily is green, and Brian is a rhino, then Gertrude is a mouse. There is a very good chance that if Brian is a rhino, or Sandra grabbed the milk, then Mary went to the office. It is unlikely that if Lily is green, or Sandra grabbed the milk, then Bernhard is a swan.
