Passage Two

　　At the University of Kansas art museum, scientists tested the effect of different colored walls on two groups of visitors to an exhibit of paintings. For the first group the room was painted white; for the second, dark brown. Movement of each group was followed by an electrical equipment under the carpet. The experiment showed that those who entered the dark brown walked more quickly, covered more area, and spent less time in the room than people in the white one. Dark brown made people more active, but the activity ended sooner. Not only the choice of colors but also the general appearance of a room affects those inside. Another experiment presented people with photographs of faces whose energy was to be commented. Three groups of people were used; each was shown the same photos, but each group was in an ordinary room—a nice office. The third was in a tastefully designed living room with carpeting. Results showed that the people in the beautiful room tend to give higher marks to the faces than those in the ugly room did. Other studies that students do better on tests taken in comfortable room than in ordinary-looking or ugly rooms.

　　Passage Three

　　The water we drink and use is running short in the world. We all have to learn how to stop wasting our limited water. One of the steps we should take is to find ways of reusing it. Experiments have already been done in this field.

　　Today in most large cities, fresh water is used only once, then it runs into waste system. But it is possible to pipe the used water to a purifying factory. There it can be filtered and treated with chemicals so that it can be used again, just as it were fresh from a spring.

　　But even if every large city purified and reused its water, we still would not have enough. Then we could turn to the oceans. All we’d have to do to make use of the seawater on earth is to get rid of the salt. This process is called desalinization, and it is already in use in many parts of the world.

　　71. The way to stop wasting our limited water is to ________.

　　A. do experiments with water B. purify the used water and reuse it
