What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall z_2: P_1(z_2) <-> Q_2(z_2). forall z_2: W_3(z_2) or Q_2(z_2). forall z_2: P_1(z_2) or ~W_3(z_2).
forall z_2: W_3(z_2) -> P_1(z_2). forall z_2: P_1(z_2) -> Q_2(z_2). forall z_2: Q_2(z_2) -> P_1(z_2).
