The goal is to avoid hitting the net , and hit the ball so that it is difficult for your opponent to hit the ball back to you . However , if your opponent hits the ball , he must also make sure the ball does n't touch the net .  Both of you may hit the ball off the ground , reflecting it into the air yet you must avoid the net .  If your opponent hits the next or makes the ball go out of bounds , then you score a point . Question: Who hits the ball over the net? Option1: tennis players Option2: instructor
