Final answer:
Democracy and authoritarianism share similarities in terms of centralized authority and potential stability in governance.
Step-by-step explanation:
Democracy and authoritarianism are two opposite forms of government, but they do share some similarities. One similarity is that both forms of government have a centralized authority that exercises power over a population. In both systems, decisions and policies are made by those in power, although the sources of authority differ. Another similarity is that in both democracy and authoritarianism, there is the potential for stability in the governance of a country.
In addition to this, democracy emphasizes citizen participation, individual rights, and rule by the people. Authoritarianism, in contrast, concentrates power in a central authority with limited political freedoms. Societies choose between these models based on political philosophies, values, and historical contexts.
