Girls and boys do not have to be brother and sister. Jumping and kicking does not always imply that someone plays.


Context: A young blond girl with a pink shirt on jumps high into the air while kicking her foot out and sticking her tongue out.
Hypothesis: A girl teases her brother by sticking her tongue out at him as she plays.

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