For how many years can Congress fund an army?

The correct answer reflects the provision in the U.S. Constitution regarding the funding of an army. Specifically, Article I, Section 8 of the Constitution grants Congress the power to raise and support armies, but it also stipulates that appropriations for such funding can only be for a term of two years. This limitation was established to ensure that the power to maintain a standing army remains under the control of Congress, reflecting the democratic principle that elected representatives should decide on military funding and authority over military forces. This mechanism prevents any potential misuse of power by executive branches or the establishment of a permanent army that could threaten civil liberties.

The other potential choices do not align with the constitutional stipulation, as funding for an army can only be allocated for two-year periods under the specified clause, emphasizing the importance of legislative oversight in matters of national defense and military readiness.
