premise: Bad Dog<br>Tom got a new dog. It was not housebroken. Tom often found his apartment messed up. He tried hard to train him to no avail. Tom wound up getting rid of it.
hypothesis: Tom adopted his new dog.
reason: The dog is new to Tom, but there is no information as to whether it is a puppy or an older dog. I think it was difficult for the AI bc there is no information regarding this.
