Ron, you stated in many posts that the article is not the issue that GMAT tests in SC, if there is an article error, there will be some other error to help us to determine the correct answer,
but according to this official problem, GMAT eventually tests the article solely. except the article use there isn't any significant difference between choice A and B?
what i mean by that statement is that the idiomatic usages of "a/an/the" are not going to be tested. if you have an instance in which the presence or absence of an article fundamentally changes the meaning of the resulting construction -- as in this case -- then that could be fair game.
another instance of this kind of phenomenon is the presence or absence of "the" in front of a number. for instance, if you say "bob and jim are the two witnesses to the crime", then you are implying that bob and jim are the only two witnesses. however, if you say "bob and jim are two witnesses...", then there very well could be more than two. (this difference may factor into e.g. the interpretation of critical reasoning problems.)
on the other hand, i do feel compelled to ask -- do we have actual verification that this is an official problem? anyone have a screenshot?
