We do not know that there is a trapped toy boat in the brook or that the person is trying to grab it. We also do not know if the person is a man or a woman.


Context: "A person wearing a striped shirt, blue jeans and blue sneakers stands on a rock in a brook." Claim: "A man is balancing on a rock to grab the trapped toy boat from the brook."
Considering the context, is the claim true, false, or unknown?
