Translate the following inference to logic notation: For all x, x is a lawyer or x is a sailor. For all x, if x works, then x is a sailor. For all x, if x were a lawyer, then x is working. For all x, if x were a sailor, then x is working. Therefore for all x, x will work or x will drink water.
forall x: P(x) or Q(x). forall x: R(x) -> Q(x). forall x: P(x) -> R(x). forall x: Q(x) -> R(x). Therefore forall x: R(x) or S(x).
