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（A）

(E) such has been an abundance of capital for commercial real estate,

此题的末尾areas in which to build , 是否是areas in which investors are to build的省略，如是，build 是及物动词后是否还少宾语？如不是完整句子应怎样写？谁是to build 之动作发出者？

got it , Thanks a lot.

求助其中倒装的解释

[求助]og20 og20 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（A） (E) such has been an abundance of capital for commercial real estate,

Choice D awkwardly separates has and been，即such has the abundance of capital been，请问这里是否使用了倒装呢，如果是倒装，那么助动词have提前就可以，比如(A) so abundant has capital been for commercial real estate that
中的形式。一直不明白，请教一下大大们！

這題在OG的解釋說的還蠻清楚的，你可以看看

such 是"of a kind"的意思，而不是像so一樣可以形容abundant

至於has 與been分開的問題，只能這麼說吧，即便是解決這個問題也不能選

再问OG20：

第一，在这里为什么要用倒装？或者说是什么情况下用倒装？

第二，全部倒装和部分倒装的区别是什么？

Choice A is best. The construction so abundant has capital been... that correctly and clearly expresses the relationship between the abundance and the investors’ response

Q1.我想是因為 原句有  so.....that 有因果關係
如果改變的話 則就破壞原本句中想表達的 因果關係
