"The first three Articles of the Constitution establish the rules and separate powers of the three branches of the federal government: a legislature, the bicameral Congress; an executive branch led by the President; and a federal judiciary headed by the Supreme Court."

This means you can rule out answers that don't have to do with the federal/national government.

"Implied powers, in the United States, are those powers authorized by a document (from the Constitution) that, while not stated, seem to be implied by powers expressly stated."

The definition of implied powers basically tells you that these powers aren't listed in the constitution.
