A. has been tested to be 200 million years old and therefore is --- ---tissue samples and has been- is SV number error

B. has been tested at 200 million years old and therefore – The same error as in A.

C. have been tested to be 200 million years old and therefore are --- The correct choice.

D. have been tested as being 200 million years old and therefore ---The clause that follows -and therefore - must be an independent clause with a verb of its own. On the other hand, we have is just a phrase without the verb for the elided subject ‘tissue samples’. – Wrong

E. have been tested at 200 million years old and therefore are dated at is not the correct idiom. – wrong

daagh: Are these questions with tag "Verbal review", official questions by GMAC? I see very little traction on these questions compared with questions having the tag "Official Guide"

Not that way; sometimes there are some low level questions to induce many to participate. This is a simple idiom based questions and hence may not interest serious students

Thanks daagh.
I see nearly 300+ questions with "Verbal Review 2018" tag and difficulty "700+" tag. This makes it diffucult to filter out questions.
Are all these questions truly provided by GMAC?

A. has been tested to be 200 million years old and therefore is - SV Agreement error
B. has been tested at 200 million years old and therefore - SV Agreement error
C. have been tested to be 200 million years old and therefore are - tested/dated at is preferred in such scenarios
D. have been tested as being 200 million years old and therefore - Awkward
E. have been tested at 200 million years old and therefore are - Correct Idiom and sentence makes perfect sense

(E) is the correct choice.
