What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_16: P_2(x_16) <-> S_16(x_16). t <-> ~S_16(a_16). ~P_2(a_16).
t -> ~S_16(a_16). ~S_16(a_16) -> t. forall x_16: P_2(x_16) -> S_16(x_16). forall x_16: S_16(x_16) -> P_2(x_16).
