原文：Design courses should be an essential element in engineering curricula. Because perceptive processes are not assumed to entail "hard thinking," nonverbal thought is sometimes seen as a primitive stage in the development of cognitive processes and inferior to verbal or mathematical thought. But it is paradoxical that when the staff of the Historic American Engineering Record wished to have drawings made of machines and isometric views of industrial processes for its historical record of American engineering, the only college students with the requisite abilities were not engineering students, but rather students attending architectural schools.
If courses in design, which in a strongly analytical engineering curriculum provide the background required for practical problem-solving, are not provided, we can expect to encounter silly but costly errors occurring in advanced engineering systems. For example, early models of high-speed railroad cars loaded with sophisticated controls were unable to operate in a snowstorm because a fan sucked snow into the electrical system.
题目：10.The author uses the example of the early models of high-speed railroad cars primarily to
(A) weaken the argument that modern engineering fan sucked snow into the electrical system.
(B) support the thesis that the number of errors in modern engineering systems is likely to
increase
(C) illustrate the idea that courses in design are the most effective means for reducing the cost of designing engineering systems
(D) support the contention that a lack of attention to the nonscientific aspects of design results in poor conceptualization by engineers
(E) weaken the proposition that mathematics is a necessary part of the study of design
我选的是C，因为觉得CD时没法排除的，但是D的lack of attention和conceptualization（尤其后者）原文没有提到？看到正确答案D时觉得C不对可能 是因为“most effective",但还是不明白D怎么体现在原文里。
希望好心人解答~谢谢~

原文第二段第一句说设计课程的缺失可能导致愚蠢却损失惨重的错误。C选项错在"the most effective"和"reducing the cost of designing engineering systems"，因为(1)原文没说是最有效的(2)文章的意思是设计课程可以减少失误带来的cost，而不是减少设计该系统本身的cost。
D选项lack of attention to the nonscientific aspects of design 等价于原文中提到的设计课程的缺失。正是因为poor conceptualization才会带来愚蠢不必要的损失。

个人观点欢迎指正
