context: We doubt that Mary went to the kitchen. Chances are slight that John left the apple. There is almost no chance that Bernhard is a lion. Chances are about even that if Mary went to the kitchen, or Bernhard is a lion, then Sumit is bored. We believe that if either Bernhard is a lion, or Mary went to the kitchen, then Jeff dropped the apple. It is probably not the case that if John left the apple, or Bernhard is a lion, then Julius is a swan.
