context: We believe that Mary dropped the apple. There is little chance that Julius is a frog. It is probably not the case that Greg is a rhino. It is certain that if either Greg is a rhino, or Mary dropped the apple, then Lily is yellow. It is improbable that if either Julius is a frog, or Mary dropped the apple, then Bernhard is a lion. There is almost no chance that if Julius is a frog, or Mary dropped the apple, then Brian is green.
hypothesis: There is a better than even chance that brian is green, and Julius is a frog.
valid_hypothesis: It is impossible that brian is green, and Julius is a frog.
invalid_hypothesis: There is a better than even chance that brian is green, and Julius is a frog.
hypothesis_assertion: Brian is green, and Julius is a frog.
