Q15:
Driving the steep road to the mountaintop Inca ruins of Machu Picchu is potentially
dangerous and hiking there is difficult. Now the Peruvian government is installing a
cable car that will make access much easier, and hence result in a large increase in
tourism. However, since the presence of large numbers of tourists tends to accelerate the
deterioration of a site, installation of the cable car is certain to result in harm to the ruins.
Which of the following, if true, most seriously calls into question the argument?
A. The daily number of tourists that are expected to take the cable car to Machu
Piccu is smaller than the original resident population of Incas.
B. The construction of the cable car terminal at Machu Picchu will require the use of
potentially damaging heavy machinery at the site.
C. Machu Picchu is already one of the most popular tourist sites in Peru.
D. Natural weathering will continue to be a more significant cause of the
deterioration of Machu Picchu than tourist traffic.
E. The cable car will replace the tour buses whose large wheels and corrosive
exhaust at present do significant damage to the site.
Answer:e

结论说安装cable car增加了旅客数量,所以cable car会对导致对遗迹得破坏

题目问削弱

因此应该找安装

cable car不会造成破坏得选项

我觉得没有特别贴切得选项

e应该是加强牙?

请指教

楼主，首先麻烦先修改一下你的标题格式。“天山”和“7"之间应该用横杠相连。这样后面的人才搜索的到，谢谢支持！

其次，你的逻辑思路太死了。削弱题并不是只有一个方向的，它可能有很多种出现的模式。建议你好好看一下置顶的lawyer的文章，看看每个题型的解题方法。比如削弱题，lawyer提到，因果型削弱的答案可能是无因有果、有因无果、他因、原因数据不正确等。你说的“cable不会造成伤害”只是其中一种“有因无果”－－有calbel但没有伤害。你忽略了其他的可能性如“无因有果”－－没有cable仍然会造成伤害。也就是答案E。
