Translate the following inference to logic notation: For all x, if x_11 works, then x_11 is a lawyer. For all x, x_11 will work. For all x, x_11 will take a plane. For all x, x_11 will take a plane if and only if x_11 will drive a car. Therefore for all x, x_11 is a lawyer and x_11 will drive a car.
forall x: P(x) -> Q(x). forall x: P(x). forall x: R(x). forall x: R(x) <-> S(x). Therefore forall x: Q(x) and S(x).
