Final answer:
The 'commerce clause' and the 'necessary and proper' clause both expand the power of Congress.
Step-by-step explanation:
The 'commerce clause' and the 'necessary and proper' clause both have the effect of expanding the power of Congress. The commerce clause, found in Article I, Section 8, Clause 3 of the U.S. Constitution, grants Congress the power to regulate interstate commerce. This has been interpreted to give Congress broad authority in areas related to commerce. The necessary and proper clause, also known as the elastic clause, found in Article I, Section 8, Clause 18, allows Congress to make laws that are necessary and proper for carrying out its other enumerated powers, further expanding its authority.
