问题     How much living space does a person need? What happens when his space requirements are not adequately met? Sociologists and psychologists are conducting experiments on rats to try to determine the effect of overcrowded conditions on man.(71)Recent studies have shown that the behavior of rats is greatly affected by space. If rats have adequate living space, they eat well, sleep well, and reproduce well. However, if their living conditions become too crowded, their behavior patterns and even their health perceptibly change. They cannot sleep or eat well, and signs of fear and tension become obvious. The more crowded they are, the more they tend to bite each other and even kill each other. Thus for rats, population and violence are directly related. Is this a natural law for human society as well? Is adequate space not only desirable, but also essential for human survival?
The passage suggests that overcrowded conditions______.
选项 A、are directly related with population
B、may cause an increase in violence
C、may lead to high birth rate
D、may bring about pollution problems
答案B
解析 推理判断题。根据文章倒数第三句“Thus for rats，population and violence are directly related．”以及上文提到的实验可推知，过度拥挤可能会导致暴力行为的增加。故选B。
