Translate the following inference to logic notation: For all x, if x climbs a mountain, then x is drinking water. For all x, if x drinks water, then x is playing squash. For all x, if x were a lawyer, then x is drinking water. There is at least one x for which x will climb a mountain or x is a lawyer. Therefore there is at least one x for which x will play squash.
forall x: P(x) -> Q(x). forall x: Q(x) -> R(x). forall x: S(x) -> Q(x). exists x: P(x) or S(x). Therefore exists x: R(x).
