Translate the following inference to logic notation: For all x, x_5 will play tennis and x_5 will drive a car. For all x, if x_5 plays tennis, then x_5 is drinking water. For all x, if x_5 climbs a mountain, then x_5 is drinking water. Therefore for all x, x_5 will drink water.
forall x: P(x) and Q(x). forall x: P(x) -> R(x). forall x: S(x) -> R(x). Therefore forall x: R(x).
