What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_11: R_11(x_11) <-> S_11(x_11). ~R_11(a_11). w_3.
~R_11(a_11) and w_3. w_3 and ~R_11(a_11). forall x_11: R_11(x_11) -> S_11(x_11). forall x_11: S_11(x_11) -> R_11(x_11).
