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: R_2(j_1) -> Q_3(j_1). forall x: R_2(x) or ~Q_3(x).
forall x: Q_3(x) -> R_2(x) can be inferred via the universal rewriting rule.
