It cannot be inferred that the child is the son or that the man is a father, let alone of this child. The water the man is in can be any body of water, not necessarily a lake at a park.


Context: A man in water throwing a little boy up in the air and waiting for him to come down so he can catch him.
Hypothesis: A father plays with his son in the lake at the park.

Given this context, determine if the hypothesis is true (Yes, no, or unknown)?
