Final answer:
The Preamble to the Constitution includes the promotion of the general welfare to indicate the government's role in enhancing the well-being of the people, alongside other goals such as securing liberty and ensuring justice. Option a is correct answer.
Step-by-step explanation:
The Preamble to the United States Constitution outlines the fundamental purposes and guiding principles of the government's role in society. One of these purposes is to 'promote the general welfare'. This phrase implies that the government has a responsibility to create conditions that benefit all citizens, which can include but is not limited to providing social services, ensuring economic stability, and maintaining a fair and competitive marketplace.
Including the promotion of the general welfare in the Preamble signifies that the framers of the Constitution recognized the importance of a government that actively works to improve the lives of its citizens. This goal is not to suggest that promoting the general welfare is the sole purpose of government (option C is incorrect). It is one of several goals listed, alongside forming a more perfect union, establishing justice, ensuring domestic tranquility, providing for the common defense, and securing the blessings of liberty.
Furthermore, the general welfare clause does not place the common good as inherently above individual interests (option B is incorrect), nor is it included simply because people asked for it (option D is incorrect). Instead, it is a reflection of the foundational belief that a just government looks after the well-being of its people, which in turn secures liberty for all (option A is the closest to the intended meaning, though the options provided seem to lack a perfect match).
