What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? S_7(c_3) <-> q_4. forall x_7: S(x_7) <-> S_7(x_7). ~q_4.
S_7(c_3) -> q_4. q_4 -> S_7(c_3). ~S_7(c_3). forall x_7: S(x_7) -> S_7(x_7). forall x_7: S_7(x_7) -> S(x_7).
