Translate the following inference to logic notation: For all x, if x_16 were a cashier, then x_16 is reading a book. For all x, if x_16 drives a car, then x_16 is playing a game. For all x, x_16 is a cashier if and only if x_16 will play a game. For all x, x_16 is not a janitor. For all x, x_16 is a janitor if and only if x_16 will read a book. Therefore for all x, x_16 will not drive a car.
forall x: P(x) -> Q(x). forall x: R(x) -> S(x). forall x: P(x) <-> S(x). forall x: ~T(x). forall x: T(x) <-> Q(x). Therefore forall x: ~R(x).
