context: There is a very good chance that Greg is a swan. It is probably the case that Bernhard is a lion. It is likely that Mary took the apple. Chances are about even that if Bernhard is a lion, or Mary took the apple, then John went to the kitchen. There is little chance that if Mary took the apple, or Greg is a swan, then Julius is white. Chances are slight that if either Bernhard is a lion, or Greg is a swan, then Emily is a sheep.
hypothesis: There is almost no chance that either Julius is white, or Bernhard is a lion.
valid_hypothesis: It is probable that either Julius is white, or Bernhard is a lion.
invalid_hypothesis: There is almost no chance that either Julius is white, or Bernhard is a lion.
