What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_5: T_2(x_5) -> W(x_5). forall x_5: W(x_5) -> T_2(x_5). forall x_5: W(x_5) -> ~Q_5(x_5). exists x_5: Q_5(x_5).
exists x_5: ~W(x_5). forall x_5: T_2(x_5) <-> W(x_5). forall x_5: W(x_5) <-> T_2(x_5).
