As other have mentioned, this is an Idiom question, and the correct idiom is "estimate to be". Here's a link to a free GMAT Idiom ebook:

I don't think this is true. In the following official question, the correct answer says "dated AT 34 million years old".

fossils-of-the-arm-of-a-sloth-found-in-puerto-rico-in-80744.html

Perhaps "estimated to be" is the only correct idiom and people have been wrong in saying "estimated at". Interesting grammar rule that I otherwise would have been unaware of.

D because "estimate to be" is the correct idiom and "fragments" matches with "provide"

its true that fragments matches with provide. But jawbone matches with provides in answer choice C.


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

"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..

But in the problem from gmat prep
With surface temperatures estimated at minus 230 degrees Fahrenheit, Jupiter's moon Europa has long been considered far too cold to support life, its 60 square miles of water thought to be frozen from top to bottom
"estimated at" is used in non underlined portion. So I mentioned the same in post above.

Dear targetdec31,
Hmmm. On a few occasions, unfortunately I have seen inconsistencies in the GMAT's own material, and it usually shows up in this form --- something never would be right in an underlined section is presented as part of the non-underlined (theoretically correct) part of the sentence. I suspect this is because the GMAC folks generate a large number of possible questions and then subject those questions to an extensive "experimental" testing period, during which focus is on the underlined portion and the alternatives --- after all, that's what determines the quality of the question. I imagine that the non-underlined portion simply does not receive the same level of scrutiny, such that sometimes something like this will slip through in the non-underlined section. Nobody's perfect, not even the people who write the GMAT.

All I can say is --- "estimated to be" is the correct idiom, and "estimated at" would never be correct as an alternative to an underlined section of a GMAT SC question.

Does this make sense?

Mike :-)

OA D


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.

Hi guys! just a refresher, enjoy!

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

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! :)

OA is D



The subject is fragments, so the verb needs to be plural (provide, not provides). B, C and E gone.

A) "estimated AT" sounds wrong because it implies you do it at a specific position of "40 to 44 million years old". So A sounds weird but we keep it as a contender

D) "estimated TO BE 40 to 44 million.." sounds much better, it preserves the intended meaning of the author instead of creating ambiguity. Since we're only concerned with A and D, D is our choice.

In this question how two verbs(estimated and provide) are present without any conjunction?

I guess estimated & unearthed are verb-ed modifier here .
Please explain.

Dear Abid,

I think you've already answered your own question! "Unearthed" and "estimated" are modifiers, so "estimated" is not parallel to "provide", and no conjunction is needed. One way to be sure of this is to remove the modifiers and see whether the subject and verb still make sense:

Paleontologists believe that fragments of a primate jawbone provide evidence of a crucial step along the evolutionary path that led to human beings.

"Fragments... provide" makes perfect sense.

Meghna
