Final answer:
The best paraphrase is that the amendment would automatically be enforced one year after ratification, without the need for additional legislative changes or actions.
Step-by-step explanation:
The best paraphrase of the excerpt would be: the amendment would become effective one year after the date of its ratification; no further legal action would be necessary. This phrase captures the essence that the law is self-executing and it would not require additional changes to current laws or legislative action to enforce it. If there are any conflicting state or federal laws, they would be automatically repealed after a year of the amendment's ratification. This simplifies the process by which the law would be implemented, thereby making it easier to enforce.
