Rock samples ---> plural subject. hence has been is incorrect and have been in correct.
Eliminate A and B.

Dated at is the correct idiom. hence E.

(D) have been dated as being 3.47 billion years old and thus
(E) have been dated at 3.47 billion years old and thus are ANSWER

The subject 'rock samples' is plural so both the verb after 'dinosaurs', 'have', and the verb before 'evidence', 'are', have to be plural.

The correct idiom is 'dated at.'

Hope that helps :).

easy breezy.. idiom usage. DATED AT and not dated to be.. therefore A, C and D out. Out of B and E , B uses HAS whereas samples-the subject is plural
There fore E is best.

Removing all the flabs i.e. here is the main sentence.

Rock samples ....[taken from the remains of an asteroid about twice the size of the 6-mile-wide asteroid tha......]has been dated to be 3.47 billion years old and thus is evidence of the earliest known asteroid impact on Earth

Rock samples is plural subject hence , 'Have' & 'are' required, dated to be - incorrect idiom usage.
Hence A, B eliminated
C Dated to be is wron indiom
D verb is missing

E - corrects Sub- verb agreement error and Idiom usage

Concept tested : SVA, IDIOM

Clearly, the ideom "dated AT" messed with me, for me it seems as if the dating of rock samples are happening AT some location when we use "dated AT".. Apparently though, it is the correct ideomatic usage and thus I stand corrected. (I picked C)

GMAC has moved away from testing SC solely on the basis of idioms. But still, you can go through the lists (no harm)

Please complete the below one and then proceed to others.

Re: Rock samples taken from the remains of an asteroid about [#permalink] New post 04 Dec 2014, 12:12
Please Help !! (Kudos for clear reply)

I am very confused on the usage of the idiom DATED AT vs DATED TO BE,

Although, i thought that DATED AT was prefered on the Gmat, I've seen both of them as right answer !!!(see link from gmatprep test2 qn 2)
I am a non native and it confuses me,
Is there a tip to choose correctly beetween the two ?
Do you have any link to an discussion, expert explanation, or else on that ?

Thank you very much !
Quentin
