What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? exists x_12: ~P_5(x_12). forall x_12: P_5(x_12) or Q(x_12). forall x_12: W_4(x_12) and Q_12(x_12).
exists x_12: Q(x_12). forall x_12: W_4(x_12). forall x_12: Q_12(x_12).
