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: W(x_11) or ~W_1(x_11). exists x_11: W_1(x_11) and Q_6(x_11).
exists x_11: W_1(x_11) can be inferred via the existential simplification rule. exists x_11: Q_6(x_11) can be inferred via the existential simplification rule. forall x_11: W_1(x_11) -> W(x_11) can be inferred via the universal rewriting rule.
