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,

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. In choice B, the repetition of so is illogical and unidiomatic. Choices C, D, and E alter somewhat the intended meaning of the sentence; because of its position in these statements, such functions to mean "of a kind" rather than to intensify abundant. Choice D awkwardly separates has and been, and the omission of that from C and E makes those choices ungrammatical.
