E. Neuroscientists have amassed, over the past twenty years, a wealth of knowledge about the brain and its development from birth to adulthood,
选A。对于D的问题是，过去的讨论帖中，大家都一致同意D由于改变句子重心被排除。
但是D的意思上，now drawing solid conclusions about how the human brain grows and how babies acquire language 可不可以是做have amassed的结果呢。。。
求指教。
感觉和这题情况很相似的是OG12-Q26，这题改变了原句强调的中心吧。
26. Emily Dickinson’s letters to Susan Huntington Dickinson were written over a period beginning a few years before Susan’s marriage to Emily’s brother and ending shortly before Emily’s death in 1886,outnumbering her letters to anyone else.
(A) Dickinson were written over a period beginning a
few years before Susan’s marriage to Emily’s
brother and ending shortly before Emily’s death
(B) Dickinson were written over a period that begins
a few years before Susan’s marriage to Emily’s
brother and ended shortly before Emily’s death
(C) Dickinson, written over a period beginning a few
years before Susan’s marriage to Emily’s brother
and that ends shortly before Emily’s death in
(D) Dickinson, which were written over a period
beginning a few years before Susan’s marriage
to Emily’s brother, ending shortly before Emily’s
death in 1886, and outnumbering
(E) Dickinson, which were written over a period
beginning a few years before Susan’s marriage
to Emily’s brother and ending shortly before
Emily’s death in 1886, outnumber
E不是改变句子重心了么。。。同问，A中的outnumbering为什么不能做前面整个句子的伴随结果。
求指教，多谢。
