The conclusion that can be drawn from the statement is that without support from Congress or the President, it is unlikely that efforts to avoid compliance with any enacted laws, including the laws governing services like mail delivery, fire services, trash collection, or police services, would be successful. Therefore, it implies that such suspensions would be illegal unless there is proper support and authority to do so. However, the specific options provided (mail delivery, fire services, trash collection, police services) are not explicitly stated in the original statement and depend on the context of the "enacted law" being referred to.
In a simplified response to point out the illegality, the answer would be that it is illegal to suspend any of these services unless permitted by law—no single option can be definitively concluded from the original statement.
