What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_5: R_1(x_5) or Q(x_5). forall x_5: Q(x_5) -> ~W(x_5). exists x_5: ~R_1(x_5) or Q_4(x_5). forall x_5: W(x_5).
forall x_5: ~Q(x_5). exists x_5: Q(x_5) or Q_4(x_5).
