Final answer:
The claim that federal disclosure requirements apply only to written materials by mortgage lenders is false, as these requirements include various forms of communication. Also, the Necessary and Proper Clause does not limit but rather extends the powers of the national government.
Step-by-step explanation:
The statement "Federal disclosure requirements apply only to the written materials provided by a mortgage lender" is false. Federal disclosure requirements extend beyond just written materials; they often include other forms of communication and disclosure practices to ensure that consumers are fully informed before making financial decisions. For example, the Truth in Lending Act (TILA) and the Real Estate Settlement Procedures Act (RESPA) require lenders to provide certain disclosures about loan terms and costs both in writing and, in some cases, through other mediums.
The statement that "The necessary and proper clause has had the effect of limiting the power of the national government" is false. The Necessary and Proper Clause, also known as the Elastic Clause, gives Congress the authority to make all laws which shall be necessary and proper for carrying into execution the enumerated powers. This has been interpreted to grant Congress a wide latitude of power and has been used to expand, rather than limit, the scope of federal governmental action.
