再讨论og－13

请教OG CR 13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 natinoal security?
(C)The machine-tool industry encountered difficulty in obtaining goverment protection against imports on ground other than defense。

找到比较好的解释：

1.文中说，国防担心他们没有能力打持久战，如果 machine-tool industry 继续shrink
而 machine tool industry却反而在国防部把进口条款和安全条款联系起来之前，继续要求进口
这就是明显的矛盾了


2.machine tool industry要求的是对进口进行限额，而不是要求进口

c的选项表明，他们找不到其他借口，只好拿国家安全来当挡箭牌
ounds other than defense.
我的问题是，继续nn帮助：

1.当某项工业萎缩，国家是增加出口限额还是减少？

2.c选项的正确翻译是什么？on grounds 什么意思？是指：m工业在得到政府保护去反对进口上有困难，这样理解对吗？
