Translate the following inference to logic notation: For all x, x_7 is an electrician or x_7 will not listen to a song. There is at least one x for which if x_7 were an electrician, then x_7 is a lawyer. For all x, if x_7 were an electrician, then x_7 is listening to a song. Therefore there is at least one x for which if x_7 listens to a song, then x_7 is a lawyer.
forall x: P(x) or ~Q(x). exists x: P(x) -> R(x). forall x: P(x) -> Q(x). Therefore exists x: Q(x) -> R(x).
