Answer: C
Step-by-step explanation:
The phrase “to form a more perfect union” is included in the Preamble of the United States Constitution as one of the reasons for creating a new Constitution. This phrase refers to the desire to improve upon the government established under the Articles of Confederation, which had proven to be ineffective in addressing many of the challenges facing the newly independent states. The new Constitution was intended to create a stronger and more effective federal government that would be better able to address issues such as trade, defense, and foreign affairs. So the correct answer would be “because the government under the Articles of Confederation had not been effective” (Option C).
