Answer: Black markets will develop to provide consumers with what they want.
Step-by-step explanation:
Shortage is a situation that occurs when the demand for a particular product is more than the goods that are being supplied or available for sale.
If there is a shortage of milk, this means that there'll be consumers who can't get milk and hence, a black market will develop. It should be noted that a black market simply refers to a market wherby illegal transactions take place. From the back market, customers who want to buy milk but can't get milk can get whet they want.
