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.

這題

我選A

原文說: 因為"大量的"觀光客會加速風景點的惡化

所以,裝置纜車注定會導致對這個風景區的傷害

原文強調的是"大量觀光客"---> damage

所以,我覺得A很合理

因為說明了觀光客沒這麼多....

請指點
