白勇语法 第七章 p.211 第40题

40. Last year, land values in most parts of the pinelands rose almost so fast, and in some parts even greater than what they did outside the pinelands.

(A) so fast, and in some parts even greater than what they did

(B) so fast, and in some parts even faster than, those

(C) as fast, and in some parts even faster than, those

(D) as fast as, and in some parts even faster than, those

(E) as fast as, and in some parts even faster than what they did

正解是(D)

我疑惑的是为什么这边those指代land values，但是后面并没有补出与rose对应的动词 did？

白勇语法全解里面没有针对这里做说明

可以请NN帮忙讲解一下吗？

谢谢
