What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? Name the inference rule being used: forall x_16: R_16(x_16) -> S_16(x_16). s. ~S_16(a_16).
s and ~S_16(a_16) can be inferred via the conjunction rule. ~S_16(a_16) and s can be inferred via the conjunction rule.
