context: There is a very good chance that Jeff went to the kitchen. It is unlikely that Bernhard is green. It is highly likely that Winona is a cat. There is almost no chance that if Bernhard is green, or Jeff went to the kitchen, then John dropped the apple. We believe that if either Jeff went to the kitchen, or Winona is a cat, then Brian is a rhino. It is probably the case that if Winona is a cat, and Jeff went to the kitchen, then Lily is a swan.
