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_1(x_15) or ~Q_15(x_15). forall x_15: Q_15(x_15). P_1(j) -> u_4.
forall x_15: Q_15(x_15) -> P_1(x_15) can be inferred via the universal rewriting rule.
