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