Answer:
Answer 1: A Two-thirds of both houses of Congress need to approve the amendment.
Answer 2: C They knew that the Constitution would have to be changed over time.
Step-by-step explanation:
The amendment process was included in the U.S. Constitution because the framers recognized that the document they were creating was not perfect and would need to be modified over time to meet the changing needs of the country. They wanted to ensure that the Constitution could be adapted to new circumstances and that future generations would have the ability to make changes if necessary. The amendment process allows for changes to be made to the Constitution while still maintaining the basic principles and framework established by the founders. This has allowed the Constitution to remain a relevant and effective document for over two centuries.
