A recording system was so secretly installed and operated in the Kennedy Oval Office that
So secret was a recording system installation and operation in the Kennedy Oval Office
It was so secret that a recording system was installed and operated in the Kennedy Oval Office
A recording system that was so secretly installed and operated in the Kennedy Oval Office
Installed and operated so secretly in the Kennedy Oval was a recording system that
题目分析：
通读原句，我们知道，“一个记录系统在the Kennedy Oval Office的秘密建立和运营”以及“Theodore C. Sorensen不知道这个记录系统的存在”之间应该具有因果关系（so that），可以排除(B)(D)；(C)中的so that位置不对，放在此处使得install和know两句之间缺少连词；(E)试图用倒装结构来表达，但是此处倒装结构有问题，应该是：so secretly installed and operated in the Kennedy Oval was a recording system that（完全倒装），排除(E)，答案为(A)。
选项分析：
略
Installed and operated so secretly in the Kennedy Oval was a recording system that
(E)试图用倒装结构来表达，但是此处倒装结构有问题，应该是：so secretly installed and operated in the Kennedy Oval was a recording system that（完全倒装），
因为秘密地是修饰安装的，而不是in哪里
