问题
单项选择题
According to the passage, why would the landowners respond to environmental concerns a. They wish to stimulate economic growth. b. They wish to improve their public image. c. They have a tradition of cooperating with the government. d. They are afraid of federal legislation.
答案
参考答案：D
解析：
[分析]： 因果关系的判断。 题干问私人土地所有者为什么对环境问题做出反应 原文最后一段第一句便给出答复“The willingness of local landowners to participate in this protection effort may have been stimulated by concerns that Congress would impose a legislative solution.”即“土地所有者们因为担心国会将对他们采取强制性的法律解决手段，所以才愿意参与这种保护活动。”由此可见，选项d的说法是正确的。[解题关键] 正确理解关键词含义，如原文中concern和impose的使用，表明当地人们的心态。
