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(x_12). forall x_12: W(x_12) and Q_12(x_12). forall x_12: P(x_12) or W_2(x_12).
exists x_12: W_2(x_12). forall x_12: W(x_12). forall x_12: Q_12(x_12).
