What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_5: W(x_5) -> T_2(x_5). forall x_5: T_2(x_5) -> Q_1(x_5). exists x_5: T_2(x_5) -> W(x_5). forall x_5: ~Q_1(x_5).
forall x_5: ~T_2(x_5). forall x_5: W(x_5) -> Q_1(x_5). exists x_5: T_2(x_5) <-> W(x_5). exists x_5: W(x_5) <-> T_2(x_5).
