What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? S_12(e) <-> q_8. ~q. q <-> q_8. forall x_12: R_12(x_12) <-> S_12(x_12).
S_12(e) -> q_8. q -> q_8. q_8 -> S_12(e). q_8 -> q. ~q_8. forall x_12: R_12(x_12) -> S_12(x_12). forall x_12: S_12(x_12) -> R_12(x_12).
