Which statement best describes the main goal of the preamble of the U.S. Constitution?

The main goal of the preamble of the U.S. Constitution is to establish the framework for a governing body. It serves as an introduction to the Constitution, highlighting the fundamental purposes and guiding principles of the government that is being formed. The preamble begins with the phrase "We the People," emphasizing that the authority of the government comes from the people. It outlines several key objectives, such as providing for the common defense, promoting the general welfare, and ensuring domestic tranquility, all of which relate directly to the framework and responsibilities of the government.

The other options do not accurately reflect the purpose of the preamble. For instance, while the declaration of independence is an important historical document, it is separate from the Constitution and its preamble. Individual rights and freedoms are more formally outlined in the Bill of Rights, which are the first ten amendments to the Constitution. Lastly, the promotion of specific economic policies is not a focus of the preamble; rather, it sets the stage for how the government should operate and serve its citizens through governance, not through economic directives. Therefore, establishing the framework for governing is the central theme reflected in the preamble.
