Explanation:

Following the aftermath of the American Revolutionary War, the thirteen colonies were busy finding the right form of government to employ and how to manage their relationship.

1. The central government's assumption of states' war debt: he saw this as a good option to improve the unity among the states

2. The creation of a National Bank: this is to make sure the country has a steady currency for the economic operation

3. The protection and stimulation of American industry: the purpose is to protect the local industry against foreign importation of goods.
