求问GWD T-3-Q21题！谢谢各位NN！
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.
我选的A 答案是E
我自己的分析是：原文说cable car→人数增加→环境恶化 结论是：cable car造成了环境恶化
我选A是因为削弱了人数增加的说法 也就是我认为削弱了这个逻辑链条的第二个环节
答案是直接指出了cable car并没有造成环境恶化
是不是题目给的条件绕来绕去 但是我们在选答案的时候只要针对题目的结论就好了啊？ |
