Translate the following inference to logic notation: For all x, x_12 will go running. For all x, if x_12 goes running, then x_12 is a lawyer. There is at least one x for which x_12 is an electrician. Therefore there is at least one x for which x_12 is an electrician or x_12 is a bartender.
forall x: P(x). forall x: P(x) -> Q(x). exists x: R(x). Therefore exists x: R(x) or S(x).
