问2个题目 想死了～～求助

第一个是149. 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
(E) as fast as, and in some parts even faster than what they did

答案D后面为什么不要did啊，如果加了可以吗？
还有一个是

Originally developed for detecting air pollutants, a technique called proton-induced x-ray emission, which can quickly analyze the chemical elements in almost any substance without destroying it, is finding uses in medicine, archaeology, and criminology.

(A) Originally developed for detecting air pollutants, a technique called proton-induced x-ray emission, which can quickly analyze the chemical elements in almost any substance without destroying it,

(B) Originally developed for detecting air pollutants, having the ability to analyze the chemical elements in almost any substance without destroying it, a technique called proton induced x-ray emission

(C) A technique originally developed for detecting air pollutants, called proton-induced x-ray emission, which can quickly analyze the chemical elements in almost any substance without destroying it,

(D) A technique originally developed for detecting air pollutants, called proton-induced x-ray emission, which has the ability to analyze the chemical elements in almost any substance quickly and without destroying it,

(E) A technique that was originally developed for detecting air pollutants and has the ability to analyze the chemical elements in almost any substance quickly and without destroying the substance, called proton-induced x-ray emission,

答案A后面的which是直接修饰technique吗？可是后面的错误答案的解释都提到 错误答案中的which是直接修饰前面的emssion了

我怎么看都差和A的格式差不多，为什么A就是对的呢～

which从句是不是修饰紧跟着他的东西？

感谢你们宝贵的时间，我复习得快奔溃了..帮帮我

我觉得those后面不应该加did，因为those是指代land values,应紧跟它的修饰语outside the
pinelands. did应加在outside the pinelands的后面。

如有不妥，请多多指正。

两个主语比较嘛，加不加did都行，不是绝对错误。同意amumu
