What is a similarity between Ancient Greece and the United States in their system of government? A They both have an oligarchy: a government controlled by the nobility
B They both have a dictatorship: a government harshly controlled by one person
C They both have a democracy: a government formed by the people
D They both have a government that controls, plans, and owns the country's economy

(help please!!!)

The answer is A they both have an oligarchy : a government controlled by the nobility.

If you need proof "Another important ancient Greek concept that influenced the formation of the United States government was the written constitution. ... The original U.S. voting system had some similarities with that of Athens. In Athens, every citizen could speak his mind and vote at a large assembly that met to create laws"

a is the final ! : )
