标题: 大全上关于一道国防的题 [打印本页] 作者: lisiberry 时间: 2017-3-9 00:58 标题: 大全上关于一道国防的题 Defense Department analysts worry that the ability of the United States to wage a prolonged war would be seriously endangered if the machine-tool manufacturing base shrinks further. Before the Defense Department publicly connected this security issue with the import quota issue, however, the machine-tool industry raised the national security issue in its petition for import quotas.
Which of the following, if true, contributes most to an explanation of the machine-tool industry’s raising the issue above regarding national security?
(A) When the aircraft industries retooled, they provided a large amount of work for tool builders.
(B) The Defense Department is only marginally concerned with the effects of foreign competition on the machine-tool industry.
(C) The machine-tool industry encountered difficulty in obtaining governmental protection against imports on grounds other than defense.
(D) A few weapons important for defense consist of parts that do not require extensive machining.
(E) Several federal government programs have been designed which will enable domestic machine-tool manufacturing firms to compete successfully with foreign toolmakers.
问题：我理解C的前部分，但不太明白other than defense.这个地方。
是不是说机械工业为了寻求保护，虽然它寻求保护的理由与国家防御没关，但（为了某种利益）以国家安全为借口来要求限制进口呢？
麻烦各位了。

紧紧抓住结论：machine tool industry requests import quota because of national security issue.
问题问你why
也就是找出 “import quota而维护machine tool industry进而维护了national security” 的原因，即为什么要import quota
AD没有提到import，无关。BE说反了。
验证C，The machine-tool industry encountered difficulty in obtaining governmental protection against imports on grounds other than defense. 发现 哦，原来是machine-tool industry自己没有得到本国政府的经济保护，选C
