context: It is probable that Brian is a lion. It is likely that Mary dropped the apple. It is likely that Julius is a swan. We believe that if Brian is a lion, or Julius is a swan, then Emily is a wolf. Chances are slight that if either Mary dropped the apple, or Julius is a swan, then Gertrude is a wolf. There is a very good chance that if either Julius is a swan, or Brian is a lion, then John went to the garden.
hypothesis: It is probably not the case that john went to the garden, and Emily is a wolf.
valid_hypothesis: It is probably not the case that john went to the garden, and Emily is a wolf.
invalid_hypothesis: It is probable that john went to the garden, and Emily is a wolf.
