Which term is the introductory part of a document such as a constitution?

• A. Primary Sources
• B. Popular Sovereignty
• C. Political System
• D. Preamble

Answer: (D)

The introductory part of a constitution explains why the document exists and the goals the government aims to achieve, often indicating who holds the authority. This opening is called the preamble. It sets the purpose and guiding principles, like stating that power comes from the people and outlining aims such as forming a more perfect union and ensuring justice and liberty. The other terms don’t fit this role: primary sources are the original documents or artifacts themselves, popular sovereignty is the principle that power comes from the people, and a political system refers to how government is organized, not the opening section. So the introductory part is the preamble.
