Final answer:
The statement is false, as the Articles of Confederation required unanimous consent from all 13 states for any amendments. The inflexibility in changing the Articles was a major flaw that was corrected in the process for amending the new U.S. Constitution.
Step-by-step explanation:
The statement that the Articles of Confederation could be amended or changed by a vote of 9 out of the 13 states is false. Under the Articles of Confederation, amending the document required a unanimous vote, meaning all 13 states had to agree to any changes. This stringent requirement often made it difficult to enact needed reforms, leading to numerous issues with the central government's capabilities.
The Constitutional Convention met in 1787 specifically to address these and other problems by revising the Articles of Confederation. This meeting ultimately led to the drafting of a new Constitution, which included a more flexible process for amendment, requiring a two-thirds majority in both houses of Congress and the ratification by three-quarters of state legislatures.
To avoid the previous challenges faced under the Articles, the framers of the U.S. Constitution ensured that the process for amending the Constitution would be achievable without requiring unanimous consent, but still demanding a significant consensus to reflect the will of the states and the populace.
