premise: Tree Surprise<br>One day, my brother and I went for a walk in the woods. We heard a mewing sound behind one of the trees. We investigated and found a kitten there. The kitten was starving so we took it home to feed it. We decided to keep the kitten as a pet.
hypothesis: The brothers rarely go walking in the woods. 
reason: The passage does not indicate how frequently the brothers go walking in the woods.
