a command economy tends to exist under a\n○ democratic government that provides little regulation.\n○…

Brief Explanations:

A command - economy is an economic system where the government makes most of the production and distribution decisions. Communist governments typically have a high - level of control over the economy, which is characteristic of a command economy. In a democratic or representative government with little or no regulation, a market - based economy is more likely to exist. Socialist governments may have elements of both market and command economies, but a command economy is most strongly associated with a communist government with a high degree of regulation.

Answer:

democratic government that provides little regulation. - Incorrect socialist government that provides some regulation. - Incorrect representative government that provides no regulation. - Incorrect communist government that provides a lot of regulation. - Correct
