说实话题目看的晕晕的，不过我是这么做的（蒙的）

题目问an explanation of the machine-tool industry's raising

the issue above regarding national security?为什么它这么做

如果你是一个企业，你在做决策之前肯定深思熟虑，考虑宏观微观局

势，而你做出的决策往往是设身处地为自己想的。只有C选项是以自

国防部的分析家们担心如果machine-tool manufacturing base进一步缩减，则会严重影响美国长期作战的能力。然而，在国防部把这个安全问题和进口配额问题联系在一起之前，machine-tool industry就已经以国家安全问题为由提出了进口配额请求。

问题：以下哪个选项最能解释：为什么machine-tool industry在国防部把安全问题和进口配额问题联系在一起之前就会以国家安全问题为由提出了进口配额请求？

注：进口配额就是对某些商品的进口直接进行限制的意思。

所以答案很明确选C。C说machine-tool industry之前在寻求贸易保护的时候，除了以防卫（国家安全）为理由以外都不可能使得政府保护他们从而限制进口。换句话说，machine-tool industry之所以早就以国家安全为理由寻求贸易保护（进口配额）就是因为找不到其他能够使政府保护他们的理由，只有这个理由美国政府一下子就接受了。

这题最大的难度不在选项，而在对argument的理解上。
