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 results in a large increase in tourisms. However, since the presence of large numbers of tourists tends to accelerate the deterioration of a site, installation of a 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 Picchu is smaller than the original resident 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.
正确答案是e,但是我觉得c有道理,原因如下:
尽管e说缆车代替大巴减少了损坏,但是并没有比较减少的损坏与人员增加的损坏谁多谁少,不形成削弱;
而c选项说picchu已经是热门的旅人景点,所以游人不会大幅的增加,形成削弱,请问我的推理何处出错了,谢谢大家的帮助!! |
