When does government regulate producers in a mixed-market economy?
a. always
b. as needed
c. as required
d. never

I believe the answer is: B. as needed

Mixed-market economy is the combination of both free market system and socialist system. Which mean that both the government and the private sectors are involved in the economy.

In the mixed market economy, the private sectors are free to choose the type of businesses they want to pursue, BUT the government would make intervention once in a while in order to ensure consumers' safety, fair competition, and stability in the market.

why do you think kush in nubia is not as well-known as egypt?

hello there!

the graphics that you have attached within the question, indicates that few people in bolivia work in industry according to its labor force.

however, the graphic that is on the right side of the picture shows the gdp sector in bolivia. this gross domestic product is a macroeconomic magnitude   that shows the monetary value of all finished goods and services within a country's borders in a specific time period. in this case, the graphic is showing the monetary value in each sector -agriculture, industry and services- of bolivia in 2012.

so, although the first graphic located at the left side indicates that not so many people work in industry, this is the second most important sector according to the gdp metrics because of the monetary value that impacts on its country. it does not need to be the most valuable one. if it makes an impact on the country's economy, it will be definitely crucial to it.
