What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? Q_3(d) <-> q_7. s. ~S(d). forall z_4: Q_3(z_4) <-> S(z_4).
s and ~S(d). ~S(d) and s. Q_3(d) -> q_7. q_7 -> Q_3(d). forall z_4: Q_3(z_4) -> S(z_4). forall z_4: S(z_4) -> Q_3(z_4).
