Translate the following inference to logic notation: For all x, if x_5 were rich, then x_5 is a server. For all x, x_5 is rich. For all x, if x_5 were a server, then x_5 is a police officer. For all x, if x_5 were a police officer, then x_5 is drinking water. Therefore for all x, x_5 will drink water.
forall x: P(x) -> Q(x). forall x: P(x). forall x: Q(x) -> R(x). forall x: R(x) -> S(x). Therefore forall x: S(x).
