What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? S(d_3) <-> S_2(d_3). ~S(d_3). forall x_13: Q_13(x_13) -> S(x_13). forall x_13: S_2(x_13) -> Q_13(x_13).
S(d_3) -> S_2(d_3). S_2(d_3) -> S(d_3). forall x_13: S_2(x_13) -> S(x_13).
