Question

what is an economic function of the u.s. government as part of the market economy?
setting the price for all goods and services
stopping competition among businesses
pushing for more externalities
dividing up the money it receives

Explanation:

In a market economy, the U.S. government does not set prices for all goods and services (that's mainly determined by supply and demand). It also does not stop competition among businesses (as competition is a key aspect of a market economy). Pushing for more externalities (which are costs or benefits not reflected in market prices) is not a positive economic function. However, dividing up the money it receives (through taxation and then allocating funds for public goods, infrastructure, etc.) is an economic function as it involves fiscal policy and resource - allocation within the economy.

Answer:

dividing up the money it receives
