context: It is highly unlikely that Greg is a lion. There is a very good chance that Sandra got the apple. There is a very good chance that Lily is white. We believe that if Sandra got the apple, or Lily is white, then Antoine is hungry. It is probably the case that if either Lily is white, or Sandra got the apple, then Julius is white. Chances are about even that if either Sandra got the apple, or Lily is white, then Bernhard is yellow.
hypothesis: It is impossible that either Antoine is hungry, or Bernhard is yellow.
valid_hypothesis: There is a better than even chance that either Antoine is hungry, or Bernhard is yellow.
invalid_hypothesis: It is impossible that either Antoine is hungry, or Bernhard is yellow.
hypothesis_assertion: Either Antoine is hungry, or Bernhard is yellow.
