context: It is unlikely that John picked up the apple. It is highly likely that Julius is a rhino. We believe that Emily is a cat. It is likely that if Julius is a rhino, or Emily is a cat, then Winona is a wolf. Chances are about even that if John picked up the apple, or Emily is a cat, then Lily is a lion. There is a very good chance that if either Julius is a rhino, or Emily is a cat, then Bernhard is yellow.
hypothesis: Chances are about even that either Lily is a lion, or Emily is a cat.
valid_hypothesis: Chances are about even that either Lily is a lion, or Emily is a cat.
invalid_hypothesis: It is almost certain that either Lily is a lion, or Emily is a cat.
hypothesis_assertion: Either Lily is a lion, or Emily is a cat.
