When voting rights frist started only wealthy land owners were allowed to vote which was an idea that was taken from the Greek Democracy and all members of the Greeek Assembly were elected their positions by citizens that they represented and were paid for their work in the public office just like the way the U.S. elects their officials. The U.S. also took the 3 branches of government from the Greek Democracy and the citizens right to exercise political power. The Constitution was an idea taken from the Roman Republic. The Roman Republic had a list of rules called the Twelve Tables (list of rules/Roman legal system) and both the Roman & U.S. Senate's deal with foreign policies.
I think the answer is D.Sparta had two kings
I believe the answer is: Aristotle, Plato, and Socrates
Aristotle and Plato promote the idea of political system and ethical values that later on develop into a democratic system of government that is used by most countries today.
Socrates on the other hand, believe that democracies had a lot of flaw and only a handful of selected people should be able to make the decision for the society, which is what adopted by countris with absolute monarchies.
