Final answer:
Democracy can emerge from oligarchy due to widespread discontent with economic inequality and the instability of oligarchic rule, leading to a demand for more egalitarian governance.
Step-by-step explanation:
Democracy often evolves out of oligarchy due to a combination of factors that include economic inequality and dissatisfaction among the population, and the inherent instability of oligarchic rule. Dissatisfaction arises when a small group makes policy decisions to maintain their privileged positions, leading to a lack of civil liberties and compounded economic inequality. This creates pressure for change and demands for a more egalitarian system, epitomized by democratic governance. Aristotle considered democracy to be a defective system that tends to serve the interests of the majority at the expense of the minority. However, oligarchies, often perceived as elected or unelected ruling elites, can also prompt calls for greater equality and representation, leading to a push towards democracy where all citizens have a vote and potentially more balanced representation. Given the provided options, the most fitting answer would be A: Due to economic inequality and dissatisfaction.
