OG12-111 A选项求教

111. The difficulty with the proposed high-speed train line is that a used plane can be bought for one-third the price of the train line, and the plane, which is just as fast, can fly anywhere. The train would be a fixed linear system, and we live in a world that is spreading out in all directions and in which consumers choose the free-wheel systems (cars, buses, aircraft), which do not have fixed routes. Thus a sufficient market for the train will not exist.

Which of the following, if true, most severely weakens the argument presented above?

(A) Cars, buses, and planes require the efforts of drivers and pilots to guide them, whereas the train will be
guided mechanically.
(B) Cars and buses are not nearly as fast as the high-speed train will be.
(C) Planes are not a free-wheel system because they can fly only between airports, which are less convenient
for consumers than the high-speed train’s stations would be.
(D) The high-speed train line cannot use currently underutilized train stations in large cities.
(E) For long trips, most people prefer to fly rather than to take ground-level transportation.

A选项不是也说明train可以guide mechanically么?这样就是train的优势,这不是削弱么?
虽然C选项确实正确


求教!谢谢!!!

题目说明的是train的劣势，削弱方法为否定劣势，提出其他优势不能直接削弱。
例如：选拔篮球队员。
     A:张三打球不让李四好，让李四去吧
     B:可是张三唱歌比李四好啊。
     B不能削弱A是张三入选
同理，题目指责的是火车的缺点，A选项虽然说明了火车的优点也不能削弱原文

这个类比不错。谢谢

A选项没有关系么，有人驾驶还是无人驾驶，不是决定其应不应该存在的重要因素。

还有另一个split是：cars buses都是文章中的例子，只是作为辅助说明free-wheel systems的。

重要因素不是你yy出来的，是原文说人们选择free-wheel system，所以其他提出的各种他因削弱都是不重要的factor了亲。。
