Translate the following inference to logic notation: For all x, if x_13 were a police officer, then x_13 is climbing a mountain. For all x, x_13 is not a police officer. For all x, x_13 will climb a mountain or x_13 will read a book. For all x, if x_13 climbs a mountain, then x_13 is a police officer. Therefore for all x, x_13 will read a book or x_13 will drive a car.
forall x: P(x) -> Q(x). forall x: ~P(x). forall x: Q(x) or R(x). forall x: Q(x) -> P(x). Therefore forall x: R(x) or S(x).
