Goronian lawmaker: Goronia's Cheese Importation Board, the agency responsible for inspecting all wholesale shipments of cheese entering Goronia from abroad and rejecting shipments that fail to meet specified standards, rejects about one percent of the cheese that it inspects. Since the health consequences and associated costs of not rejecting that one percent would be negligible, whereas the cost of maintaining the agency is not, the agency's cost clearly outweighs the benefits it provides.

Knowing the answer to which of the following would be most useful in evaluating the lawmaker's argument?

• AAre any of the types of cheeses that are imported into Goronia also produced in Goronia?  
• BHas the Cheese Importation Board, over the last several years, reduced its operating costs by eliminating inefficiencies within the agency itself?  
• CDoes the possibility of having merchandise rejected by the Cheese Importation Board deter many cheese exporters from shipping substandard cheese to Goronia?  
• DAre there any exporters of cheese to Goronia whose merchandise is never rejected by the Cheese Importation Board?  
• EHow is the cheese rejected by the Cheese Importation Board disposed of?
