请教有争议的T-3-Q21

T-3-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 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.

题目讨论的是installation of a cable car is certain to result in harm to the ruins.
削弱它就要 否定 harm
题目large number of tourists---> cable car harm

答案E 也有问题 replace the tour buses 换了更大了 不一定就减少人数了。
我选的是D 它因法为什么错了呢？

发表一下我的拙见。

原文：增设电缆车使游客大增，然而，因为游客太多，使景区恶化，所以缆车不利
增设缆车——>游客多——>景区恶化
=>缆车——>景区恶化
削弱：直接削弱，缆车没有恶化景区，反而替代了原来给景区带来大量污染的旅游巴士，缓和了景区恶化

这能算削弱题吗？

不懂，为啥D不对

zhongyaya

哦。。我知道D哪里不对了。

D说的是天气，可是天气和坐车还是坐缆车根本无关。

天气是一直存在损害着遗迹的呀。。。

D是无关选项
天气可以和缆车一起加重环境的影响
