Which is an example of representative government?

This option does not exemplify representative government because the military is not an elected body. Instead, treaties are typically negotiated by the executive branch, specifically by the President or their appointed representatives, without direct input from the electorate.

While this process involves appointed officials, it does not represent the general population's will. The Cabinet is comprised of individuals chosen by the President, and their approval of nominees is not a reflection of the democratic process inherent in representative government.

This choice is also incorrect because the Supreme Court does not ratify constitutional amendments; rather, amendments require approval by a supermajority in Congress and ratification by the states. The role of the Supreme Court is to interpret laws, not to enact them, which distinguishes it from the legislative function of representative government.
