Question

a country has a
command
economy when its government holds full control over economic activity.
when competition is present within an economy, with limited government intervention, it is considered a
mixed - market
economy.
one sign of transition is the establishment of
fair labor
government restrictions

Explanation:

1. For the first blank: A command economy is defined by the government having full control over economic activities, so "command" fits.
2. For the second blank: A mixed - market economy has limited government intervention and allows competition, which is a key characteristic of such an economy.
3. For the third blank: When an economy is transitioning, one sign can be the establishment of government restrictions (as economies in transition may start to regulate certain aspects, or in the context of moving towards a more regulated or different economic system, government restrictions being established is a sign of transition). Or if considering fair labor, but government restrictions are more in line with regulatory changes during transition.

Answer:

1. command
2. mixed - market
3. government restrictions
