ESL / EFL Quiz 314

Two parallel lines (tape may be used) should be placed across the front wall such that the bottom edge of one line is 3 feet above the floor and the bottom edge of the other line is 1 foot above the floor. At all times, any ball that hits the front wall (i) below the 3 foot line and (ii) either on or above the 1 foot line must be returned before it bounces a third time. However, if the ball hits below the 1 foot line, it must be returned before it bounces twice. If the ball hits on or above the 3 foot line, the ball must be returned as described in the basic return rule.
