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: exists x_11: R_3(x_11) or ~Q(x_11). forall x_11: P_6(x_11) -> R_3(x_11). forall x_11: P_6(x_11) or ~W_2(x_11). forall x_11: W_2(x_11) or Q(x_11).
forall x_11: W_2(x_11) -> P_6(x_11) can be inferred via the universal rewriting rule. exists x_11: Q(x_11) -> R_3(x_11) can be inferred via the existential rewriting rule.
