One advantage the federal system of government has over unitary is what?

One advantage the federal system of government has over unitary is that it allows for greater regional autonomy and local representation. In a federal system, power is divided between the central government and regional or state governments. This allows each region or state to have a certain degree of self-governance, as they can make and enforce their own laws and policies within their jurisdiction. This decentralized approach promotes local representation, as regional governments better understand the specific needs and preferences of their populations. It also allows for diversity in governance, as different regions can implement policies that reflect their unique social, cultural, and economic characteristics.
