Translate the following inference to logic notation: For all x, if x_7 were a lawyer, then x_7 is drinking water. For all x, x_7 will drive a car or x_7 is a scientist. For all x, x_7 will drive a car if and only if x_7 is a lawyer. For all x, if x_7 were a scientist, then x_7 is drinking water. Therefore for all x, x_7 will drink water.
forall x: P(x) -> Q(x). forall x: R(x) or S(x). forall x: R(x) <-> P(x). forall x: S(x) -> Q(x). Therefore forall x: Q(x).
