The statement suggests that compliance with enacted laws is mandatory unless there is support from Congress or the President to avoid it. Therefore, it implies that any efforts to suspend services that are mandated by law would not be likely to succeed without such support.
Given the options provided, no specific conclusion about the legality of suspending any particular service (police, trash collection, fire services, mail delivery) can be definitively drawn based only on the statement. The focus is on the lack of successful avoidance of compliance with enacted laws rather than on the legality of suspending specific services.
However, based on the context, the conclusion is that without support from Congress or the President, it may be assumed that suspending any of these services without legal backing could face challenges in legitimacy.
Thus, the best response to conclude from the statement would be that it is generally not viable to suspend legally required services without the necessary legislative or executive support.
