在official guide 上逻辑部分第13题我看了几遍也不懂。请哪位高手帮我翻译一下。
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 coonnected this security issue with the import quota issue, howver, the machine-tool industry raised the national security issue in its pettion for import quotas.
您有空顺便翻下正确答案吧：
The machine-tool industry encountered difficulty in obtaining governmental protection against imports on grounds other than defense.
