What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? exists x_11: R(x_11) -> T(x_11). forall x_11: R_5(x_11) -> W(x_11). forall x_11: Q_11(x_11) -> R_5(x_11). forall x_11: T(x_11) <-> Q_11(x_11).
forall x_11: Q_11(x_11) -> W(x_11). forall x_11: T(x_11) -> Q_11(x_11). forall x_11: Q_11(x_11) -> T(x_11).
