20. An array of tax incentives has led to a boom in the construction of new office buildings; so abundant has capital been for commercial real estate that investors regularly scour the country for areas in which to build.
(A) so abundant has capital been for commercial real estate that
(B) capital has been so abundant for commercial real estate, so that
(C) the abundance of capital for commercial real estate has been such,
(D) such has the abundance of capital been for commercial real estate that
(E) such has been an abundance of capital for commercial real estate,
答案：Ａ
og解释里有这样一句：
Choice D awkwardly separates has and been
D中用的是部分倒装，如果这不对，那应该用完全倒装吗？ＯＧ解释中倒确实没有说Ｅ中的完全倒装有问题。但是我查了很多语法资料，都没有说such...that有这样的用法。在以前的讨论中也没有结论。
请帮忙解释～～

两个知识点
1) such that
l such + Noun + that是对的. 这里such表示of a kind. 如OG255: the loans are seriously delinquent or in such trouble that…
l such + adj. + that在GMAT中必错. 用so + adj. + that 来表示加强.
2) 倒装
弄懂such that的用法后, 就可以看出D和E的such后缺了个名词. 比如说加个example.
这里D和E都是全倒装. an abundance of capital for commercial real estate是主语. 还原后是: an abundance of capital for commercial real estate has been such example.
OG说D is awkward是因为been不能插在主语中间. 这里只能有2种形式: 1)such example has been the abundance of capital for commercial real estate 2) such example has the abundance of capital for commercial real estate been
Answer A是半倒装. 主语是capital.
原形: capital has been so abundant for commercial real estate
全倒: 1) so abundant for commercial real estate has been capital
2) so abundant for commercial real estate has capital been
