Answer:
Sugar mills will not sell to private businesses, but rather sell to the government. This will force the price back up to $18.75
Step-by-step explanation:
When there is a situation that will result in fall of equilibrium price, sellers can protect themselves by creating artificial scarcity in the private sector.
By selling to the government they are still engaging in business. The private firms will have to pay more for scarce sugar in the market, thereby pushing the price back up.
