Translate the following inference to logic notation: For all x, x_9 is not a lawyer. There is at least one x for which if x_9 reads a book, then x_9 is a lawyer. For all x, x_9 will read a book. Therefore there is at least one x for which x_9 will take a plane.
forall x: ~P(x). exists x: Q(x) -> P(x). forall x: Q(x). Therefore exists x: R(x).
