What does the Constitution primarily do?

The Constitution primarily serves to define the structure and powers of government while also protecting the rights of individuals. It establishes the framework for the federal government, detailing the roles of the legislative, executive, and judicial branches, thereby ensuring a system of checks and balances. Additionally, the Constitution includes the Bill of Rights, which enumerates specific rights and liberties afforded to individuals, thereby safeguarding personal freedoms from government infringement.

This comprehensive approach to government structure and individual rights reflects the founders' intention to create a balanced system that upholds democratic principles and guarantees civil liberties, making the answer about defining the government and protecting rights the most accurate representation of the Constitution's purpose.
