提问唐老师，这道题我的做题思路是：题目说一下选项weaken了作者的一个理论，看题干最后一句，我理解的阅读重心是“从安全层面出发的不充分会导致很多后果”，最后对比选项，因为出现“equipment-storage building”我感觉题干没讲就排除BCE，选D，思路哪有问题？

提问唐老师，先跟您说下我的做题思路，首先看题目理解问题是“作者比较可能同意以下关于mtn的？”然后会原文定位到最后一句，有一个impossible，对比选项选了一个有不可能意思的，选了E。后来对答案选D，想问下老师这个思路哪里出了问题？D中past、today‘s gm提到了吗？

Which of the following can be inferred from the passage about the Hopis' geographic situation between 1680 and 1880?
请问张慧雯老师，为什么这道题不选A呢？原文中有讲到geographical isolation有让Hopi People远离疾病，那是不是就能infer isolation帮助他们免遭人口的降低（第一段也有提到这个阶段人口在降低），另外怎么能得出C这个答案呢？
