The following question are based on the following graph. The curves D and S represent the market demand and supply curves for farm products in 1960. The curves D₁ and S₁ represent the market demand and supply curves for farm products in 2000. It is supposed that there were no support programs in either year.

-The relatively large shift in the supply curve over the 40 years illustrates that
A) the quantity of food demanded does not vary much with the price of food because food is a necessity.
B) consumption of food per capita faces natural limits and hence responds by only a small amount to changes in per capita income.
C) farmers have only limited control over their outputs.
D) there has been rapid technological change in agriculture.
E) poor climatological conditions led to decreasing harvests.

The relatively large shift in the supply curve from S to S₁ over the 40 years indicates that there has been a significant increase in the production of farm products. This can be attributed to rapid technological change in agriculture, which has led to improved productivity and efficiency. Options A and B are not supported by the graph as both demand curves show a significant shift over the 40 years. Option C is also not supported as farmers have the ability to control their outputs through the use of technology and farming practices. Option E is not supported as there is no indication in the graph of poor climatological conditions affecting the supply or demand of farm products.
