What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_12: P_2(x_12) <-> P(x_12). exists x_12: T_3(x_12) or P_2(x_12). forall x_12: W_1(x_12). forall x_12: T_3(x_12) -> P(x_12).
forall x_12: P_2(x_12) -> P(x_12). forall x_12: P(x_12) -> P_2(x_12).
