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_11: P_7(x_11) -> Q_11(x_11). exists x_11: P_7(x_11) or ~P_1(x_11). forall x_11: P_11(x_11) or ~Q_11(x_11).
forall x_11: Q_11(x_11) -> P_11(x_11) can be inferred via the universal rewriting rule. exists x_11: P_1(x_11) -> P_7(x_11) can be inferred via the existential rewriting rule.
