Final answer:
Popular sovereignty addressed a weakness from the Articles of Confederation by establishing a stronger central government.
Step-by-step explanation:
Popular sovereignty addressed a weakness from the Articles of Confederation by establishing a stronger central government with more authority. Under the Articles of Confederation, the national government was too weak to effectively address challenges such as servicing war debt, resolving commercial disputes, and maintaining national defense. Popular sovereignty shifted power to the people and allowed them to elect representatives who could make decisions on behalf of the nation as a whole, leading to the creation of a stronger federal government under the U.S. Constitution.
