Q19:

New genetic evidence—together with recent studies of elephants’ skeletons, tusks, and other anatomical features—provide compelling support for classifying
                Africa’s forest elephants and its savanna elephants as separate species.

A.     provide compelling support for classifying

B.     provide compelling support for the classification of

C.     provides compelling support to the classification of

D.     provides compelling support for classifying

E.      provides compelling support to classify

answer: D

看了前人的讨论，都是在D、E中争论中，我想知道有没有统一的结论？

是不是E不对是因为前面是gene,所以用to的话没有发出的对象呀？

我觉得如果看是provide ....to do ...那么 classify的逻辑主语有问题

如果把to classify看成是修饰support,那么for 比to 好

为什么support for doing比support to do好

当support作动词讲时，是vt，不能加to，也就是说没有support to的用法

当support作名词讲时，可以support to或者support for，但后要接sb or sth

这样答案只有在C、D中选，而如果选C，则需要在and 后加of，所以选D
