What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? S_14(c) <-> R_14(c). forall x_14: R_14(x_14) <-> S_14(x_14).
S_14(c) -> R_14(c). R_14(c) -> S_14(c). forall x_14: R_14(x_14) -> S_14(x_14). forall x_14: S_14(x_14) -> R_14(x_14).
