context: It is almost certain that Jessica is a sheep. There is a better than even chance that John dropped the apple. It is highly likely that Fred went to the hallway. It is probably not the case that if either Fred went to the hallway, or John dropped the apple, then Bernhard is a frog. It is almost certain that if either Fred went to the hallway, or Jessica is a sheep, then Lily is gray. We doubt that if Jessica is a sheep, and Fred went to the hallway, then Julius is white.
hypothesis: It is probably not the case that either Jessica is a sheep, or Julius is white.
valid_hypothesis: There is a very good chance that either Jessica is a sheep, or Julius is white.
invalid_hypothesis: It is probably not the case that either Jessica is a sheep, or Julius is white.
