求助一题GWD,明天考!

The computer company's present troubles are a result of techno- logical stagnation, marketing missteps, and managerial blunders so that several attempts to revise corporate strategies have failed to correct it.
    

A  so that several attempts to revise corporate strategies have failed to correct it.

B   so that several attempts at revising corporate strategies have failed to correct
            

C   in that several attempts at revising corporate strategies have failed to correct them

D   that several attempts to revise corporate strategies have failed to correct

E   that several attempts at revising corporate strategies have failed to correct them

这道到底应该选什么呢

我怎么觉得选D?答案是B?

我选D的理由是.如果用so that (逻辑表结果)的话,that后面是一完整的句子, B不对,因为correct是动词. A不对,因为后面的it没有referent.

C in that表原因, 因为attempts fail 所以 问题是 blah blah ...不对 C错

D,E 把so that变成了 定语从句,修饰前面的名词,这个时候correct不用加动词.所以 E错 D 对

支持D. stevegt朋友讲得很对.

D中的that限定性修饰technological stagnation, marketing missteps, and managerial blunders, 逻辑很严紧.  that本身做宾语成分, 所以D中correct后不用再加宾语.

B中correct的宾语省了, 我个人觉得没道理. 而且them指代谁呢? present troubles, 还是technological stagnation, marketing missteps, and managerial blunders?

ps: LZ good luck!!!
