For all x, if x_13 takes a plane, then x_13 is not an electrician. For all x, x_13 is a doctor or x_13 will drink water. For all x, if x_13 were a doctor, then x_13 is an electrician. Therefore it is raining.
forall x: P(x) -> Q(x). R(a) or p. forall x: R(x) -> ~Q(x). forall x: S(x) or P(x). forall x: S(x) -> Q(x). Therefore p.
