Final answer:
A dictatorship can efficiently respond to a national crisis by quickly making decisions without the need for legislative approval or public consensus, but this efficiency often comes at the cost of civil liberties and human rights.
Step-by-step explanation:
The question asks why a dictatorship might respond more efficiently to a national emergency than other forms of government. Dictatorships, which concentrate power in the hands of a single individual or a small group, can often bypass the checks and balances, as well as the debate and discussion inherent in more democratic systems. As such, decisions can be made and implemented swiftly without the need for consensus or approval from a legislative body or the public. This can be particularly advantageous during a crisis situation, where quick and decisive action is required.
However, it is important to note that such efficiency may come at the cost of civil liberties, human rights, and public voice. Decisions made in a dictatorship often reflect the will of the leader, rather than the needs of the populace. While dictatorships can respond efficiently to crises, the means by which they sustain power, such as intimidation, violence, and control over the media, often oppress and distress the population. Elections in authoritarian regimes may not ensure legitimacy, as they can be marred by manipulation and coercion.
