context: It is probably not the case that Bernhard is green. It is probably the case that Sandra got the apple. There is a very good chance that Brian is a frog. Chances are about even that if either Sandra got the apple, or Bernhard is green, then Lily is a lion. We doubt that if Sandra got the apple, or Brian is a frog, then Greg is a swan. There is little chance that if Bernhard is green, or Brian is a frog, then Gertrude is a mouse.
hypothesis: There is almost no chance that greg is a swan, and Gertrude is a mouse.
valid_hypothesis: There is almost no chance that greg is a swan, and Gertrude is a mouse.
invalid_hypothesis: It is probable that greg is a swan, and Gertrude is a mouse.
hypothesis_assertion: Greg is a swan, and Gertrude is a mouse.
