Q21:
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.

该题答案是E，我选了C。感觉题目说得是因为游客人数有可能增加导致环境恶化，E说得事实无法反驳这个理由亚。

文中的结论是由于有人很多会加速遗址的变坏,所以装缆车当然会对遗址造成伤害. 我觉得C和文中结论无关. E正好说明缆车比现在的tour bus 好,是对文中结论的反驳.

不觉得这样的逻辑很怪吗？缆车代替卡车，虽然解决了一些细节矛盾，但是文中的说的是缆车代来的客流量会导致对旅游地的损坏，那么反驳也应该从这个方向发展，才有说服力。比如，游客是高素质的从不乱涂乱画。找个鸡毛蒜皮的好处，就能反驳文章的论点，好像有点强盗逻辑。
