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_17: T_4(x_17) -> S_17(x_17). q -> T_4(a_17). q or ~S_17(a_17).
S_17(a_17) -> q can be inferred via the rewriting rule.
