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: q -> S_32(a_32). forall x_32: R_32(x_32) -> S_32(x_32). p_4 or q_4. p_12 -> ~S_32(a_32). R_32(a_32) or q. ~p_4.
q_4 can be inferred via the disjunctive syllogism rule.
