PrepTest 45, Section 3, Question 23
Agricultural economist: Over the past several years, increases in worldwide grain production have virtually ceased. Further increases will be extremely difficult; most usable farmland is already being farmed with near-maximal efficiency. But worldwide demand for grain has been increasing steadily, due largely to continuing population growth. Hence, a severe worldwide grain shortage is likely.
