【再请教一个语法点：句子，ing结构的修饰问题】

25. 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,
 Now drawing...
    (E) Neuroscientists have amassed, over the past twenty years, a wealth of knowledge about the brain and its development from birth to adulthood,


OG对于D的解释有说now drawing conclusions看起来是修饰了adulthood，可是我好像在老prep语法笔记中见过{句子，V-ing}形式的，V-ing的主语为句子的逻辑主语，那么drawing的主语就是Neuroscientists，没有问题啊，那么OG得解释又怎么理解呢？


所以想请问大家关于S+V+O,ving...的ving的修饰有没有什么规定之类的？

我也想晓得这个问题啊~~~ 搞不懂这个ING~

魔法潇灵

我认为D选项是改变了句子的重心所以错的~~~

这个是OG上的一题，OG上貌似只是说很awkard什么的来排除D选项，但是manhattan上讲所有的考点分为G+M+C，这个题目凭借G（语法）考点只能排除BCE，那么最后A和D只能通过M（meaning 语义）来判断，也就是楼上说的句子语义表达重心发生了改变……
