context: It is certain that Brian is a rhino. There is a better than even chance that John moved to the office. Chances are slight that Mary went to the kitchen. There is almost no chance that if Mary went to the kitchen, and Brian is a rhino, then Yann is tired. It is probably the case that if either Brian is a rhino, or Mary went to the kitchen, then Julius is a swan. We doubt that if Mary went to the kitchen, or Brian is a rhino, then Sandra took the milk.
