context: We doubt that Winona is a cat. It is probable that Mary moved to the office. It is probably not the case that Jeff dropped the apple. There is a very good chance that if either Mary moved to the office, or Jeff dropped the apple, then Sumit is bored. There is a very good chance that if Winona is a cat, and Mary moved to the office, then Bernhard is a lion. There is little chance that if either Winona is a cat, or Mary moved to the office, then Fred left the milk.
