Translate the following inference to logic notation: For all x, if x_3 drives a car, then x_3 is an artist. There is at least one x for which if x_3 were an artist, then x_3 is reading a book. For all x, x_3 will not drive a car. For all x, if x_3 reads a book, then x_3 is driving a car. Therefore there is at least one x for which x_3 is not an artist.
forall x: P(x) -> Q(x). exists x: Q(x) -> R(x). forall x: ~P(x). forall x: R(x) -> P(x). Therefore exists x: ~Q(x).
