context: We doubt that Mary put down the milk. There is almost no chance that Daniel got the football. Chances are slight that Julius is gray. It is probably not the case that if Mary put down the milk, and Daniel got the football, then Jessica is a wolf. We believe that if Julius is gray, and Mary put down the milk, then Bernhard is green. It is unlikely that if either Julius is gray, or Daniel got the football, then Greg is a lion.
hypothesis: It is certain that greg is a lion, and Jessica is a wolf.
valid_hypothesis: It is impossible that greg is a lion, and Jessica is a wolf.
invalid_hypothesis: It is certain that greg is a lion, and Jessica is a wolf.
hypothesis_assertion: Greg is a lion, and Jessica is a wolf.
