161. Based on the growth rates of large modern reptiles such as the Galapagos tortoise and examinations of fossils of juvenile dinosaurs, scientists estimate that the largest dinosaurs probably lived to be between 100 and 200 years old.

(A) Based on the growth rates of large modern reptiles such as
(B) On the basis of growth rates of large modern reptiles such as
(C) Based on the growth rates of large modern reptiles like
(D) On the basis of growth rates of large modern reptiles, like those of
(E) Based on such growth rates as those of large modern reptiles like

选B而不是C，原因是on the basis of XX and XX中"and" 连接两个名词，而based on XX and on XX, 中“and”连接两个介词短语吗？？

但是C中的”like“算错吗？ 

大家来帮忙啊～谢谢！

base 和compare只能用被动态。根据OG解释，只能是sth is(are)based on sth.不能是sb is based on.具体题目忘了，好像在靠后部分。

所以，分词开头，后面主句，科学家是主语，不能搭配。没办法就换成了一个短语形式的词组。

like不能用于举例子。
