Rock samples........have been dated....and thus are
This eliminates A and B, incorrect usage of "has"
option D, "are" is missing. incorrect usage "thus evidence", We need a linking verb "are" to connect the subject "rock samples" with its verb "evidenced"
I would like to know if there are any other errors in D.
Option C changes the meaning, "dated to be"
Option E Clear and concise.
OA?

ISnt the subordinate clause modifying the asteroid?
If true, then the verb should be singular.
I am little confused here. Can anyone please explain?

First of all there is no subordinate clause. Indication of that is there is no comma,schumi_gmat wrote:ISnt the subordinate clause modifying the asteroid?

Independent clauses are differentiated either through semi-colon or cordinating conjunction.
Subordinate clauses or phrases are always introduced with comma.
Coming to your question.
What can be dated here. Only "Rock samples taken from remains of asteroid"
Rock samples = plural, have= plural
Hope its clear.

PC, my undersatnding was -Subordinate clauses or phrases are always introduced with comma.

Subordinate means non essential or non restrictive clauses. Such clauses are marked with commas
That is an essential or restrictive modiifer means its not subordinate/non-essential and hence no commas ( as you understood)
In the sentence, we have that meaning we have restrictive modifer and not subordinate or non essential modifier
hence, no commas are there
hence, you reference to that clause as subordinate is incorrect

There is one little exception to the rule that I mentioned.
If the subordinate clause is an adverb clause, introduced at the end of the sentence, comma is not used to separate it from the main clause.
Hope this helps.

I apologize for the delayed response. Here is the difference between the two.gmat009 wrote:Can you explain why "dated to be" changes the meaning of sentence
Samples dated at 3 million years old - dated back in time
Samples dated to be 3 million years old - actual dated time
Let me know if you guys think otherwise, to be honest I am confused myself now.
