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: ~s_3 or s_1. s_3 or W(a_17). forall x: ~W(x).
W(a_17) or s_1 can be inferred via the resolution rule. R_1(a_17) -> s_3 can be inferred via the rewriting rule.
