Translate the following inference to logic notation: For all x, x_6 is a police officer. For all x, x_6 will work or x_6 is a janitor. For all x, if x_6 were a janitor, then x_6 is an artist. For all x, x_6 will not work. Therefore for all x, x_6 is a police officer and x_6 is an artist.
forall x: P(x). forall x: Q(x) or R(x). forall x: R(x) -> S(x). forall x: ~Q(x). Therefore forall x: P(x) and S(x).
