In a market with price controls, there can be or of goods and services.

I believe the answer is shortages, surpluses
If the price controls that given is too low, no businesses will be willing to produce that commodities which lead to the shortages of goods and services.
On the other hands, of the price controls that given is too high, no consumers want to buy that products/services which will lead to surpluses

Abortion would be the most interesting topic to me
