第十五套GWD的一道语法题：20: GWD-18-Q19
New genetic evidence—together with recent studies of elephants’ skeletons, tusks, and other anatomical features—provide compelling support for classifyingAfrica’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

答案选D, 我想请问选D的原因是“provide for doing sth”? 还是 “support for”?  并且“provide to” 这种用法是否正确？
谢谢给位啦，我自己想脑子都想糊了~

1. 主语是New genetic evidence，所以谓语是单数CDE备选
2. support for的关系，所以选D

3. 多加一句；即便没有support for/to的关系，E比C好，因为GMAC偏好用verb而不是noun,所以在相同的意思，语法没有问题的前提下，选择那个用verb的词
