Translate the following inference to logic notation: There is at least one x for which if x_10 were a politician, then x_10 is taking a plane. For all x, x_10 will play a game if and only if x_10 is a politician. For all x, if x_10 takes a plane, then x_10 is not a lawyer. For all x, x_10 is a lawyer. Therefore there is at least one x for which x_10 will not play a game.
exists x: P(x) -> Q(x). forall x: R(x) <-> P(x). forall x: Q(x) -> ~S(x). forall x: S(x). Therefore exists x: ~R(x).
