单项选择题
Why are the private lands surrounding Glacier National Park so important
A．They function as a hunting preserve.
B．They are restricted to government use.
C．They are heavily populated.
D．They contain natural habitats of threatened species.
答案
参考答案：D
解析：事实细节的找寻和判断。根据题干线索找寻到原文第一段第三句可知“This land is an important part of the habitat and migratory routes for several endangered species that frequent the park．”即“这片(私人)土地是几种频频光顾公园的濒危物种的栖息地和迁徙必经之地”。由此可见，选项d的说法与原文相符，是正确的。 注意：正确找到相关信息处，并将原文和选项关键信息作对比。
