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_15: P_15(x_15) or ~Q_15(x_15). P_15(j_3) -> r_3. forall x_15: Q_15(x_15).
forall x_15: Q_15(x_15) -> P_15(x_15) can be inferred via the universal rewriting rule.
