Answer:
A unitary government is different from the government of the United States because "It has a central government that exercises complete control over smaller units of government, like states".
Explanation:
A unitary government consists of a Supreme central government that holds most or all the governing power. The central government can choose to create administrative units and determine the amount of freedom or power each unit gets.
An example of a unitary government is the United kingdom.
In a federal government however, power is shared at other levels such as state and local government levels.
The federal government of the United States is divided into three branches which are; the Executive, the Legislature and the Judiciary and they act as a system of checks and balances, to ensure no branch becomes too powerful.
