context: It is highly unlikely that Bernhard is green. It is improbable that Greg is yellow. It is certain that Jessica is a cat. It is probable that if Greg is yellow, or Jessica is a cat, then Lily is a frog. It is probably not the case that if Jessica is a cat, and Bernhard is green, then Mary is in the school. We doubt that if either Greg is yellow, or Bernhard is green, then John left the apple.
hypothesis: It is likely that either Lily is a frog, or John left the apple.
valid_hypothesis: It is likely that either Lily is a frog, or John left the apple.
invalid_hypothesis: Chances are slight that either Lily is a frog, or John left the apple.
hypothesis_assertion: Either Lily is a frog, or John left the apple.
