Translate the following inference to logic notation: For all x, x_6 will not drive a car or x_6 is an electrician. For all x, x_6 will take a plane. For all x, x_6 will drive a car or x_6 is an astronaut. For all x, if x_6 were an astronaut, then x_6 is not taking a plane. Therefore for all x, x_6 is an electrician.
forall x: ~P(x) or Q(x). forall x: R(x). forall x: P(x) or S(x). forall x: S(x) -> ~R(x). Therefore forall x: Q(x).
