what was the major difference between Greek and Roman democracy?

A The Romans elected people to run their govt
B The Greeks had everyone who was eligible participate in govt decisions
C Roman democracy included everyone while Greek democracy included only free, white men
D Roman democracy was developed prior to Greek democracy

If by Greeks they mean Athenians I would say B.

The major difference between Greek and Roman democracy can be found in option C. While the Romans did elect people to run their government, like modern representative democracy, the Greeks had a more direct form of democracy where all eligible citizens participated in government decisions.

To arrive at this answer, you can compare the political systems of ancient Greece and Rome. In ancient Athens, the birthplace of democracy, all free, adult, male citizens were expected to participate in governmental decision-making. This direct form of democracy was known as "direct democracy" because eligible citizens would gather in the Assembly to debate and vote on laws and policies. On the other hand, in Rome, the citizens elected representatives to make decisions and run the government on their behalf. This system was known as "representative democracy" or a "republic," which is closer to how modern democracies function.

Option D is incorrect because Greek democracy, originated in Athens in the 5th century BC, is considered the earliest known form of democracy. Roman democracy, known as the Roman Republic, was developed later, in the 6th century BC, and evolved into an imperial system over time.

Therefore, option C, which correctly highlights that Roman democracy included everyone while Greek democracy included only free, white men, is the major difference between the two systems.
