A) The members of the U.S. House are elected by the people. CORRECT This option directly exemplifies republicanism because it shows how the people exercise their sovereignty by electing representatives to the House of Representatives. The House is the only chamber of Congress originally designed to be directly elected by the people, reflecting the principle that government authority flows from the consent of the governed. This arrangement ensures that the legislative branch remains responsive to the will of the citizens, a core tenet of republican government.
B) Powers are shared between the national and state governments. INCORRECT This statement describes federalism, not republicanism. Federalism is the division of power between a central government and constituent political units, such as states. While both federalism and republicanism are integral to the U.S. Constitution, they address different aspects of governance. Federalism focuses on the distribution of authority, whereas republicanism focuses on the source of political power and the method of representation.
C) Justices of the U.S. Supreme Court are nominated by the president. INCORRECT This option illustrates the principle of checks and balances and the separation of powers, not republicanism. The president's power to nominate justices is subject to Senate confirmation, demonstrating the system of shared powers among the executive and legislative branches. While this process involves representative institutions, it does not directly reflect the idea that the people elect their lawmakers, which is the essence of republicanism.
D) The amendments provide an overview of the purpose of government. INCORRECT This statement is vague and does not accurately describe any specific constitutional principle. The amendments, particularly the Bill of Rights, outline individual liberties and limitations on government power, but they do not provide an overview of the purpose of government. The Preamble to the Constitution serves that purpose, and the amendments are not directly tied to republicanism. Therefore, this option is incorrect.
