Final answer:
The terms and conditions in a Certificate of Authenticity (C of A) are legally enforceable, which means that they are binding and can be enforced in a court of law. The necessary and proper clause is used to expand, not limit, the power of the national government, making the statement false. The Constitutional Convention met in 1787 originally to revise the Articles of Confederation, which is true.
Step-by-step explanation:
The Terms and Conditions in a Certificate of Authenticity (C of A)
The terms and conditions stated in a Certificate of Authenticity (C of A) are indeed legally enforceable. This means, when a Certificate of Authenticity is issued for a product, especially in the art world, it serves as a guarantee that the item is genuine as described. These certificates can be important in legal situations, such as proving the authenticity of a piece.
The Necessary and Proper Clause
The necessary and proper clause, also known as the elastic clause, is part of the U.S. Constitution that grants Congress the power to pass all laws necessary and proper for carrying out the enumerated list of powers. The clause has actually been used to expand the power of the national government rather than limit it. Therefore, the statement is false.
The Constitutional Convention
The Constitutional Convention indeed met in 1787 with the initial intention of revising the Articles of Confederation. However, it resulted in the creation of a new Constitution entirely. Hence, this statement is true.
