Answer:
The three types of government are quite different from each other.
Step-by-step explanation:
Autocracy is a type of government in which only one person rules the government. Citizens cannot vote in an autocratic type of government.
Whereas, oligarchy is the type in which government is run by a few rich and wealthy people.
Theocracy is a type in which God or a divine power is believed to be supreme and can be ruled by any government.
The similarity between autocracy and oligarchy is that citizens cannot vote on both the governments.
