9. It has been argued that the consumer has benefited from agricultural technology in the United States. Consumers are spending, on the average, a decreasing proportion of their income on food.

Which of the following is the most logical completion of the passage above?
(A) incomes will continue to rise
(B) the proportion of income spent on food has declined more sharply than rises in real income warrant
(C) technological costs constitute a substantial portion of the cost of food production
(D) the quantity of food produced by American farmers has increased
