21.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

believe  后面跟的应该是句子，但是上面两个动词unethered 和 estimated应该都是分词短语修饰the fragment的，请问这个从句里面是不是没有谓语;

如果belive后面跟的不是从句，那么应该是blieve that fragment sth 但是句子里有没有sth这部分

总之觉得这个句子不完整，请教大家，谢谢！
