What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_7: Q(x_7) <-> S_7(x_7). t <-> Q(a_7). ~s. t <-> s.
t -> Q(a_7). t -> s. Q(a_7) -> t. s -> t. ~t. forall x_7: Q(x_7) -> S_7(x_7). forall x_7: S_7(x_7) -> Q(x_7).
