单选题 If humans use up too much soil—which they have often done and are doing—then they will starve down to the carrying capacity of their habitat. This is nature's "indifferent" ______.
  • A. flexibility
  • B. justice
  • C. plasticity
  • D. sensibility
【正确答案】 B
【答案解析】[解析] 四个选项的意思分别是：flexibility弹性，适应性，机动性，挠性；justice公平，公正；plasticity可塑性，塑性；sensibility感情，感受能力。句意是，如果人类消耗了太多的土壤(他们经常这样做，而且正在做)，他们的栖息地就只能提供基本的承载能力，这就是大自然的无情审判吧。所以正确答案是B选项。
