premise: Backyard Camping<br>John and his friends were camping in his backyard. Late that night, the boys heard a growling noise. A large shadow appeared on the tent door. The tent flap flew open and the boys screamed. John's father laughed hysterically at their reaction.
hypothesis: John's father could not have been the source of the growling noise and large shadow.
reason: It's pretty obvious to a human that John's father was the likely source of the scare; I have no idea why this was hard for the AI.
