Two young boys on either a boat or platform during spring or summer, one of whom is preparing to throw a ball.
The boys are playing ball, and music is on the radio.
The fact one boy is preparing to throw a ball doesn't necessarily imply that they are playing ball. The fact that the boys are on a boat or platform doesn't indicate that music is on the radio.
