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: W(a_5) -> s_1. forall x_6: Q_6(x_6) -> W(x_6). forall x_6: R(x_6) -> Q_6(x_6).
forall x_6: R(x_6) -> W(x_6) can be inferred via the universal transitivity rule.
