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: w -> ~r_11. ~u or r_11. u or R_17(a_17). forall x_17: ~R_17(x_17).
R_17(a_17) or r_11 can be inferred via the resolution rule. R_1(a_17) -> u can be inferred via the rewriting rule.
