context: It is unlikely that Lily is a rhino. It is likely that Mary dropped the apple. It is probably not the case that Gertrude is a cat. There is a better than even chance that if Gertrude is a cat, and Mary dropped the apple, then Julius is a lion. It is impossible that if Gertrude is a cat, or Mary dropped the apple, then John moved to the office. It is highly unlikely that if Mary dropped the apple, and Gertrude is a cat, then Bernhard is a swan.
