The only choices to look at are A and D since the rest don't conjugate the verb correctly. Fragments...provide...
D is idiomatic, thus correct.

IMO D
B, C & E are out because of incorrect subj-verg agreement... fragments - provides... besides they are not idiomatic
A is simply not idiomatic

Subject verb agreement and idiom estimate. estimate as being and estimated at are wrong idioms. That leaves us with C, D, E. Fragments is plural. So the verb should be provide. That leaves us with D!

of what was

If E was what is displayed above, would it have been correct?
Cause OG says provides is incorrect , it says nothing about 'estimated as' . The above mentioned sentence seems correct to me.

Estimated To be : Reference to some time period ..... For eg here 40mn yrs

E : Thus even if SV disagreement is fixed as mentioned by u, IT will boil down to Idiomatic Usage and Estimated As in this context will Lose over Estimated To Be ......., E will be wrong.

Hi tejastalak,

You are right in your reasoning that subject verb pairs "fragments and provide" and "jawbone and provides" match. However, if you see the sentence, it intends to say that actually the "fragments of Jawbone" provided the evidence. Using "fragments" as the subject of the verb "provide" would express the idea in a better way. Choice (D) does in fact say that "fragments provided the evidence"; moreover, it is more concise than (C), making it an even better choice than (D).

Hope it helps

OA: D

I guess the trick is to understand the difference between 'estimated at' and 'estimated to be'. Since at is a preposition, it should be followed by a noun, whereas 40 to 40 million years old is not. Hence the structure is inaccurate. Furthermore 'estimated to be' is the proper idiomatic usage which includes the infinitive to make sure a valid range can be described.

Good one zazoz!

Regards,
A

That was something nice ... which took under 20 seconds. I did not even read all the choices
Wish all the SC were of similar difficulty on the GMAT

The correct answer is "D" because the idiom is " estimated to be ".

"fragments" is plural so the only possible options are (A) and (D).

"estimated at" vs "estimated to be" - "estimated to be" is better. Choose (D).
So yes, for this example, you need to know this idiom..
