It really depends on which era, if the question asks about the Roman Republic, then it would be a republican government. In Ancient Rome, an aristocracy was used. In the Roman Empire, the emperor was the main man, but he also had a senate.

Federalism, or the dual roles of state and national government, is part of the system of sharing power in government. Within the system of separate powers, however, the framers of the Constitution provided for "national" or "federal" supremacy. This meant that the national government was supreme in regards to many issues in relation to state governments, as enumerated by the Constitution.
