请教OG-SC-136

136. Although schistosomiasis is not often fatal, it is so debilitating that it has become an economic drain on many developing countries.

it is so debilitating that it has become an economic
it is of such debilitation, it has become an economical
so debilitating is it as to become an economic
such is its debilitation, it becomes an economical
there is so much debilitation that it has become an economical

答案：A，C为什么不好呢？so ...as to 的用法：前面是系动词，两者的发起是同一事物，就可以用so as to ,C也好啊？为什么不对？谢谢！

LZM书中讲：so ... as to ,仅用于简单的系表结构中，且结构状语的主语与主名的主语一致。
so...that: 用于其它一切复杂结构（无论结果状语的主语与主句的主语是否一致）

按LZM的，A，C都可以啊，为什么C不对？

以下是引用wane在2003-3-15 12:12:02的发言：
is it 多余。。。。

wane,it is 怎么多余了？

引用OG的原话：

C uses an awkward and wordy construction in place of a " that..."Clause.

而且在这个再普通不过的让步句中，也没必要用倒装呀。（而且直觉上不觉得C选项让你很不舒服吗？）

其实这题就是考的"So, that" 的用法。

注：， OG 上171 题也是关于"So that"用法的。

另，我觉得"is it"是不能省的，否则就变成了dangling sentence了

其实就是OG的解释令我费解。到底OG是什么意思啊？
