Answer: three things that these three governments have in common are:
- they all have effective governance
- they have a population
- they have territory
Explanation:
The similarity between unitary, federal, and confederate forms of government is that they are government and exercise the certain form of the powers to their respective areas.
Government refers to the authority which rules the entire nation. It is the association of the people working together to serve the nation and act for the welfare of the nation. The government also functions to save the nation from the outsiders.
All the three form of the government that is unitary, federal, and confederate allocated the powers differently.
Although it may transfer certain authority to regional governments, a unitary state only has one constitutional level of government that is responsible for almost everything.
A federal state has two or more levels of government that are explicitly stated in its constitution: a central level of government and a second level of government that can take the shape of provinces, states, prefectures, cantons, or oblasts.
A confederation is a voluntary alliance of completely sovereign members that are typically much more powerful than the central government, and who have the power to leave the confederation or overturn it on a variety of issues.
