27.Paleontologists believe that fragments of a primate jawbone unearthed in Burma and estimated at 40 to 44 million years old provide evidence of a crucial step along the evolutionary path that led to human beings.

(A)at 40 to 44 million years old provide evidence of

(B)as being 40 to 44 million years old provides evidence of

(C)that it is 40 to 44 million years old provides evidence of what was

(D)to be 40 to 44 million years old provide evidence of

(E)as 40 to 44 million years old provides evidence of what was
我看到答案是D选项，我疑惑，为什么句子里没有连词，有一个 estimate， 一个be，为什么还可以用provide，难道不是出现双谓语了吗？

水一下。
我觉得
unearthed in Burma 和 estimated to be 40 to 44 million years old 都是作了 a primate jawbone 的后置定语。
谓语是  provide
