B

Of all the sciences, only two are subjects that have a direct (直接的) and noticeable effect on our lives every day. One is meteorology, the study of weather. Heat, cold, sun and rain affect us in many ways—in the kind of clothing we wear, for example, and the types of activities we do outdoors. Economics is the other science that affects the everyday lives of all of us. Each time we spend money, or it is spent on us, we are contributing (贡献) the economic life of our country and, in fact, of the world.
Most people have a basic understanding of the weather, but how many people feel comfortable with the subject of economics Often, economics seems to be a mysterious (神秘的) subject. Newspapers and television use terminology (术语学) that can resemble (像；类似) a foreign language. They speak of the gross national product, the cost of living, the prime rate, the money supply, productivity, the unemployment rate, the balance of payments, and so forth.
In some
A. the study of economics
B. the study of weather
C. the study of painting
