Translate the following inference to logic notation: For all x, if x_18 were an artist, then x_18 is a poet. For all x, x_18 is a poet or x_18 will drive a car. For all x, x_18 is fast. For all x, if x_18 were a poet, then x_18 is an artist. There is at least one x for which x_18 is not an artist. Therefore there is at least one x for which x_18 will drive a car and x_18 is fast.
forall x: P(x) -> Q(x). forall x: Q(x) or R(x). forall x: S(x). forall x: Q(x) -> P(x). exists x: ~P(x). Therefore exists x: R(x) and S(x).
