One advantage the federal system of government has over confederal is that it allows for a stronger central government with defined powers and responsibilities. One advantage the federal system of government has over unitary is that it allows for a balance of power between the central government and the regional or state governments.

Reword this for me?

The federal system of government offers the advantage of a more robust and well-defined central government, distinguishing it from a confederal system. Moreover, the federal system ensures a balanced allocation of power between the central government and regional or state governments, setting it apart from a unitary system.
