标题: Having done问题
Neuroscientists, having amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood, are now drawing solid conclusions about how the human brain grows and how babies acquire language.

(A) Neuroscientists, having amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood, are

(B) Neuroscientists, having amassed a wealth of knowledge about the brain and its development from birth to adulthood over the past twenty years, and are

(C) Neuroscientists amassing a wealth of knowledge about the brain and its development from birth to adulthood over the past twenty years, and are

(D) Neuroscientists have amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood,

(E) Neuroscientists have amassed, over the past twenty years, a wealth of knowledge about the brain and its development from birth to adulthood,

答案A，请问这里的D选项，后面drawing可以当结果状语来理解么？

有now在，怎么看都不像个结果吧？
想说是结果状语，起码得把now去掉。

从意思上看
无论经过多长时间的研究，drawing conclusion不是一个被动，被“导致”的结果，是那个什么学家主动的动作。

从语法上看
前面是现在完成时，后面接一个结果状语...感觉怪怪的。
你找一下分词做结果状语的例子
He fired, killing one of the passers-by.
He died, leaving his wife with five children.

前面的动作都是一般过去式。随着动作发生，结果马上出现的，才会用结果状语。
纯属个人理解~~欢迎讨论~~哈哈

我觉得核心是 drawing conclusion 和主句的逻辑会发生改变。。。
