Final answer:
The statement on notarizing a document is false, as a notarization includes verifying identity and intent. Ancient seals were indeed used on clay documents and had value beyond their functionality. The necessary and proper clause is falsely associated with limiting government power; it actually expands it.
Step-by-step explanation:
The statement regarding the notarization of a document is false. Notarizing a document involves more than simply signing it and attaching your seal/stamp. A notary public must follow a series of steps which include confirming the identity of the individual signing the document, ensuring that the individual is signing of their own free will and without duress, and that they understand the contents of the document. Only after fulfilling these steps can a notary legally attach their signature and notarial seal, which serves as a certification of the steps taken.
Regarding ancient seals, the statement is true. Seals were often rolled upon clay documents to create a positive impression. Also, seals had value beyond just their practical use, as some were appreciated for their presumed magical properties or aesthetic appeal.
As for the statement about the necessary and proper clause, the answer is false. The necessary and proper clause, often called the elastic clause, has had the effect of expanding the power of the national government, not limiting it, by granting Congress the ability to make all laws which shall be necessary and proper for carrying into execution the enumerated powers given by the Constitution.
