What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_2: W(x_2) <-> T_3(x_2). exists x_2: W(x_2) <-> P(x_2).
forall x_2: W(x_2) -> T_3(x_2). exists x_2: W(x_2) -> P(x_2). forall x_2: T_3(x_2) -> W(x_2). exists x_2: P(x_2) -> W(x_2).
