Which of the following is NOT part of the basic structure of the Constitution?

The Bill of Rights is a significant component of the American Constitution, but it is actually not considered part of the original basic structure of the Constitution. The basic framework comprises the Preamble, the seven articles outlining the branches of government, and the process for amendments.

The Preamble sets the stage for the Constitution's purpose and guiding principles. The seven articles detail the federal government's structure and the powers assigned to each branch: Legislative, Executive, and Judicial. Additionally, the amendments section provides a process for making changes to the Constitution, allowing it to evolve over time.

The Bill of Rights, which consists of the first ten amendments to the Constitution, was introduced later to address concerns regarding individual liberties and rights, hence it is separate from the original structural components. Its primary function was to guarantee specific rights and freedoms to citizens, responding to calls for a clearer delineation of these protections. As such, it is recognized as an important addition but not an original part of the Constitution's foundational framework.
