单选题. Ask three people to look out the same window at a busy street corner and to tell you what they have seen. Chances are that you will receive three different answers. Although each person sees the same scene, each one perceives something different about it. Perceiving goes on in our minds. Of the three people who look out the window, one may say that he saw a policeman giving a cyclist a ticket. Another may say that he saw a rush-hour traffic jam at the intersection. The third may tell you that he saw a woman trying to cross the street together with four children. For perception is the mind's interpretation of what the senses—in this case our eyes—tell us. Many psychologists today are trying to determine how a person experiences or perceives the world around him. Using a scientific approach, these psychologists set up experiments in which they can control all of the factors.

But the industrial performance of agriculture is even more important than this. For in nations where the productivity of farmers is low, most of the working population is needed to raise food and few people are available for production of investment goods or for other activities required for economic growth. Indeed, one of the factors related most closely to the per capita income (人均收入) of a nation is the fraction of its population engaged in farming. In the poorest nations of the world, more than half of the population lives on farms. This compares sharply with less than 10% in Western Europe and less than 4% in the United States. In short, the course of economic development in general depends in a fundamental way on the performance of farmers. This performance, in turn, depends on how agriculture is organized and on the economic environment, or market structure, within which it functions. In the following pages the performance of American agriculture is examined. It is appropriate to begin with a consideration of its market structure.1. This passage is most probably ______.
