Neurosciensts, having amessed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood, are now drawing solid consultants about how the human brain grows and how babies acquire language.
A
B. Neurosciensts, having amessed..years, and are
C. Neurosciensts amassing a weath of knowledge....years, and are
D. Neurosciensts have amessed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood,
E.Neurosciensts have amessed, over the past twenty years, a wealth of knowledge about the brain and its development form birth to adulthood,


正确答案为a， 我觉得d 也对啊，但是og上说后面的drawing...有修饰前面adulthood的嫌疑，可是drawing...不是现在分词且前面有逗号，应该修饰临近句子的主语做伴随状语吗，怎么会修饰adulthood......
