The statement that best explains the differences between the two passages is:
Common Sense argues for the purpose of government, while the Federalist Papers argues for the structure of government.
In "Common Sense," Thomas Paine discusses the necessity and justification of government in terms of individual rights and the protection of property, emphasizing its purpose. On the other hand, James Madison's "Federalist 51" focuses on the organization and internal mechanisms of government that ensure the separation of powers and checks and balances, highlighting its structure.
