What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_11: W(x_11) <-> S_11(x_11). ~S_11(a_11). t_3. t_3 -> q_12.
q_12. ~S_11(a_11) and t_3. t_3 and ~S_11(a_11). forall x_11: W(x_11) -> S_11(x_11). forall x_11: S_11(x_11) -> W(x_11).
