求助：刘振民语法中两道题疑惑

各位大侠：在看刘振民语法的11章中遇到两道题，比较困惑，不知有没有高手帮忙解答一下：

E11-30 Unlike other arachnids, which have their nerve cells evenly distributed along their bodies, the scorpion's nerve cells are clustered in its head, like a mammal's.

A)bodies, the scorpion's nerve cells are clustered in its head, like a mammal's.

B)bodies, the scorpion's head has a cluster of nerve cells, as a mammal does.

C)body, the scorpion has a cluster of nerve cells in its head, as a mammal does

D)body, nerve cells...

答案B).  我选了C), 虽然Scorpion's head 跟前面的arachnids 不怎么match,但their之后按照对应关系也是跟Bodies的复数形式啊.

E11-40 She was a child prodigy, and Clara Schumann developed into one of the greatest pianists of her time.

A)She was a child prodigy, and clara schumann

B)a child prodigy, Clara Schumann

C)Child prodity that she was, clara schumann

D)Clara Schumann has been a child prodigy , and she

E)Being a child prodigy, clara schumann

答案是B)，同位语。 但偶觉得E）也解释得过去啊，表伴随状况。难道是不如B简洁吗？

C)body, the scorpion has a cluster of nerve cells in its head, as a mammal does

这个才正确, 你手里的"答案"错了~
