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

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

(E) as 40 to 44 million years old provides evidence of what was

D, the best choice, correctly follows estimated with to be. The other choices present structures that are not idiomatic when used in conjunction with estimated. Choices B, C, and E all mismatch the singular verb provides with its plural subject, fragments, and in choices C and E, what was is unnecessary and wordy. In choice C, the use of the verb phrase estimated that it is produces an ungrammatical sentence.

Predicted at/ estimated at is unidiomatic

2. shold indicates a condition, as also x carry on as y is idiomatic

3. with the intention of doing

4. Refer to OG199,231,149,8,19

Here "it" indicates the mentioned "a new priciple", it will be absurd to assume that a new priciple will be adpoted in past

First "lack" might be lacks...have. Could you confirm at your earliest convenience?

it (is)+adj+ to do

difficulty in doing is an idiomatic expression
