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: R_11(x_11) -> Q_7(x_11). forall x_11: R_11(x_11) or ~Q_7(x_11). forall x_11: P_11(x_11) -> Q_11(x_11). exists x_11: Q_11(x_11) -> R_11(x_11).
exists x_11: Q_11(x_11) -> Q_7(x_11) can be inferred via the existential transitivity rule. exists x_11: P_11(x_11) -> R_11(x_11) can be inferred via the existential transitivity rule. forall x_11: Q_7(x_11) -> R_11(x_11) can be inferred via the universal rewriting rule.
