Translate the following inference to logic notation: For all x, y is a police officer if and only if y will drive a car. For all x, if y were a server, then y is a police officer. Therefore for all x, if y were a server, then y is driving a car.
forall x: P(x) <-> Q(x). forall x: R(x) -> P(x). Therefore forall x: R(x) -> Q(x).
