What is a common characteristic of authoritarian governments?

The correct answer highlights that a common characteristic of authoritarian governments is the suppression of political dissent. Authoritarian regimes often maintain power by limiting or outright eliminating opposition and criticism. This suppression can take many forms, including censorship of the media, restrictions on freedom of speech and assembly, and persecution of political opponents. Such actions are intended to create an environment where the ruling authority can operate without challenge, maintaining strict control over the political landscape.

In contrast, the other choices describe characteristics not typically associated with authoritarian regimes. High levels of citizen involvement in governance pertain more to democratic systems where public participation is encouraged. Decentralized power structures suggest a distribution of power that allows for local governance and representation, which is inconsistent with the concentrated power seen in authoritarian regimes. Open competition for leadership roles is also more characteristic of democratic systems, where multiple candidates can vie for leadership positions and where fair elections are held.
