After an earthquake several years ago in the country of Altrus—the first in over acentury—many communication cables in the country were damaged. Afteranother, more recent earthquake, very few communication cables weredamaged.
Which of the following, if true, most helps to explain why many communicationcables were damaged in the first earthquake but few were damaged in thesecond earthquake?
(A) In between the two earthquakes, the government of Altrus initiated aprogram emphasizing the use of cellular phones that do not rely on the use ofcommunication cables.
(B) The magnitude of the first earthquake was roughly the same as themagnitude of the second earthquake.
(C) Many of the communication cables damaged in the first earthquake were inpoor condition already, and they were subsequently replaced by newer,stronger cables.
(D) Most of the cables damaged by the first earthquake were at least one foot incircumference.
(E) The first earthquake was several magnitudes weaker than the secondearthquake.
正确答案是C
可是我觉得A也没有错，因为改用移动手机，所以cables减少了，因此damaged也少了，毕竟文章说的不是比例而是用的many/ very few这样的数量，所以我觉得也没错啊？请NN帮忙解释一下吧！谢谢！
材料上给出的解释是：
Answer choice (A): This answer may explain why usage rates of the cables havedropped over the years, but that was not the issue in the stimulus. The issue was about damage to those cables, not the actual use of the cables.
Answer choice (C): This is the correct answer, and this answer offers an explanationfor the difference above. If many of the cables in the first earthquake were old, theywould be more prone to damage. But, if those cables were then replaced by newer,stronger cables, in the second earthquake they would be less prone to damage. Sincethis scenario allows all sides of the situation to be correct and it explains how thesituation could occur, this is the correct answer.
