Driving the steep road to the mountain-top Inca ruins of Machu Picchu is potentially dangerous and hiking there is difficult. Now the Peruvian government is installing acable 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.
This question has confused me.
Following words made it difficult for me to make the right choice.
1) Access easier - If the access to the site is going to be easy, then tourists are responsible for the deterioration. Therefore, cablecars+moretourists = deterioration. Answer choice should counter that - which means BOTH (cablecars+moretourists) do not = deterioration. And if A is true, there is another cause of deterioration....in this case, answer A makes more sense.
2) The answer choice D says "natural weathering...MORE SIGNIFICANT CAUSE....which, if true (as mentioned by the question itself), will continue to be a major reason that deterioration takes place and not "cablecars+moretourists"
I am leaning more towards D versus E or A purely relying on the words "More Significant cause" because i feel all the three options ( E, A, D) if true can question the argument.
