我很赞成楼主关于“D 中 how to 的宾语是synthetic growth hormone, 意思是说在scientist没有学会如何make之前，要从尸体的脑垂体中小心的取下。但是synthesize意思是人工合成的，在自然界中是不存在的。因此如何选D，就出现了逻辑错误。
C 避免了这个错误，把synthetic 换成动词，这样宾语就成了 growth hormone, 后面的逻辑就正确了。” 这块的分析。

但是关于it因为位置的远近，增加其更好的这一属性持保留意见。
谢谢楼主分享！

哈哈，synthesize和synthetic导致后边it的指代完全不一样，这题真是狡猾！

支持lz的解释，觉得e-gmat和babybearmm，甚至manhattan gmat里面对于这道题的解释都差强人意。

这个题目表面看是active／passive voice，其实考点仅仅是it指代a synthetic growth hormone还是the growth hormone的区别。仅此，有时是我们被表面考点忽悠了。

Notice how in choice D the test makers have changed the voice of one of the verbs. Now the sentence uses active voice “scientists had to painstakingly remove…”. This changes the meaning of the original sentence since it now adds new information that “scientists” actually had to remove the hormone. This information is not present in the original choice. And hence this choice by “adding” to the meaning of the sentence changes the meaning and hence is incorrect. Carefully notice that this sentence does not have any grammatical errors.

ron还有一个解释：
i.e., it implies that the people who learned to make the hormone were exactly the same people who previously had to extract it from human cadavers.
that's not a reasonable meaning, so you are absolutely right about eliminating on those grounds. nicely done.
