For all y_2, y_2 will play squash if and only if y_2 will play a game.
For all y_2, if y_2 cooks, then y_2 is driving a car. For all y_2, if y_2 plays squash, then y_2 is playing a game. For all y_2, if y_2 drives a car, then y_2 is cooking. For all y_2, if y_2 plays a game, then y_2 is playing squash. For all y_2, y_2 will not drive a car.
