Verified Answer :

The Constitution replaced the Articles of Confederation because it held tru to the ideas of federalism--that the main power of the nation should come from a strong central government, not the individual states.

The advantage of Federalism is that national issues are
handled by the National Government: For example

  1. National Currency--money
  2. Interstate Trade
  3. Armed forces
  4. Foreign Relations--treaties.

While local issues are handled by local government. For
example: Local is called State--the 50 states.

  1. Education 3. Driving laws.
  2. Marriage/divorce laws 4. Alcohol laws.

It allows each level of government to operate where it is
believed that the people's best interests will be served.
Hope that helps.
