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

(A) so fast, and in some parts even faster 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（D）

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

为什么不补出动词did,主句中是land values  rose ，那么从句中也应该是land values did 啊？求教
