Translate the following inference to logic notation: For all x, if y plays squash, then y is drinking water. For all x, y will play squash or y is a musician. For all x, if y drinks water, then y is running. For all x, y is a musician if and only if y will go running. Therefore for all x, y will go running.
forall x: P(x) -> Q(x). forall x: P(x) or R(x). forall x: Q(x) -> S(x). forall x: R(x) <-> S(x). Therefore forall x: S(x).
