The correct answer to this open question is the following.
Although there are no options attached we can say the following.
What do you think are the advantages and disadvantages of ancient Athens's approach to choosing its governments?
The advantage is that when Athenian leader Cleisthenes established democracy as the new form of government in Athens, Greek citizens had the chance to elect their rulers. This was so good to end with kings and dictators, allowing the ancient Greek citizens to participate in elections and choose the best individual capable to rule the city-state.
On the other hand, the disadvantage was that only a limited number of Athenians could participate in the election because not all the people who lived in Athens were considered citizens of this city-state. For instance, women were considered citizens, neither slaves. So decisions were biased on the criteria of so few people that could have the wrong impression and make the wrong choice.
