What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? p_2 or S_16(a_16). forall x_16: R_16(x_16) <-> S_16(x_16). ~R_16(a_16).
~S_16(a_16) -> p_2. forall x_16: R_16(x_16) -> S_16(x_16). forall x_16: S_16(x_16) -> R_16(x_16).
