What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? ~R_12(d_3). q_1 -> S_12(d_3). forall x_12: R_12(x_12) <-> S_12(x_12). p -> q_1.
p -> S_12(d_3). forall x_12: R_12(x_12) -> S_12(x_12). forall x_12: S_12(x_12) -> R_12(x_12).
