Translate the following inference to logic notation: For all x, if x_6 climbs a mountain, then x_6 is driving a car. For all x, x_6 is not a musician or x_6 will listen to a song. For all x, x_6 will drive a car if and only if x_6 will listen to a song. For all x, x_6 is a musician or x_6 will climb a mountain. Therefore for all x, x_6 will drive a car.
forall x: P(x) -> Q(x). forall x: ~R(x) or S(x). forall x: Q(x) <-> S(x). forall x: R(x) or P(x). Therefore forall x: Q(x).
