The United States dairy industry argues that tariffs on imported milk should be increased to protect dairy farmers. They base the justification for an increased tariff on the high mortgages on farmland in the United States. However, cattle and hog ranches in the United States also pay mortgages on United States land, and yet they are not demanding increased tariffs.
Which of the following, if true, would best support the dairy industry's argument against the challenge made above?
A. Dairy farms are generally closer to urban and suburban areas, where the costs of land are greater and the mortgages higher, than are cattle and hog ranches.
B. The sectors of the economy most affected by the relatively high cost of land in the United States — manufacturing and commercial development — are not well protected by tariffs.
C. No industries other than the dairy industry have asked for an increase in tariffs in the past ten years.
D. There are many industries in which the proportion of revenues devoted to mortgages is much higher than in the dairy industry.
E. The costs of producing milk and dairy products in some countries are so low that no reasonable tariff could eliminate them as competitors.
