Final answer:
The quote from the Preamble about providing for common defense is specifically reflected in Article I, Section 8, where Congress is granted the power to collect taxes and maintain armed forces.
Step-by-step explanation:
The quote "we the people of the United States, in order to ... provide for the common defence" is reflected in Article I, Section 8 of the Constitution, which outlines the powers of Congress. This section explicates Congress's authority to collect taxes, duties, imposts, and excises, all of which are necessary to provide for the common defense and general welfare of the country. In particular, it grants Congress the power to raise and support armies and to provide and maintain a navy, clearly linking the provision for common defense mentioned in the Preamble with the specific legislative responsibilities assigned to Congress.
