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_10: ~P_10(x_10) or R_10(x_10). forall x_10: P_10(x_10) or R(x_10). R_10(a_8) -> r. q -> r. R(a_8) -> q.
R(a_8) -> r can be inferred via the transitivity rule. forall x_10: R(x_10) or R_10(x_10) can be inferred via the universal resolution rule.
