Whenever we have a 'one of the xxx that/which/whoxxx' construction the verbs needs to agree with the preceding clause. (with one exception)
Here the subject of the preceding clause is Omega-3 Sources (pl) so verbs need to be plural as well.

A. supports the immune system and promotes--SV Disagreement
B. support the immune system as well as promote-appears fine to me
C. support the immune system and is a promoter of-Is useage is incorrect (Sv disagreement)
D. support the immune system and are promoters of --Also OK but a bit akward 'are promoters of health of the heart'
E. support the immune system and are the promoters of increased-- verbose and changes the meaning of the sentence

OA is D. But I'm not convinced

What's the OE?

Hi dentobizz, I agree with you.
I choose B because it was correct and less awkward than D. This Question is from the economist free test and they havent provided any OE.

Gramatically both B & D seem to be fine.

For some reason,based on meaning analysis, I thought "Sources are promoters of X" seemed correct than "sources promote Y"

I'm happy to share my two cents on this. :-)

Frankly, I am not impressed with the quality of the question.

To determine the number of the first verb, "promotes" vs. "promote", we need to know which of two options is true:
(1) all Omega-3 sources, or at least the best ones, together promote the immune system & promote heart health; in this case, plural verb "promote" is correct.
or
(2) among Omega-3 sources, only salmon oil, only the "one", promotes the immune system & promote heart health; in this case, singular verb "promotes" is correct.
But here's the thing: the sentence provides absolutely no way to determine which of those two is true, so to determine the correct grammar, we need to bring in outside knowledge about biochemistry and human health. That's ridiculous! Good GMAT SC questions require absolutely no outside knowledge. Because the prompt (A) suggest option #2, I would argue that all the other options change the meaning. How are we suppose to know the outside-the-sentence facts of the situation?

Furthermore, the OA's preference of the noun "promoter" over the verb "promotes" flies in the face of what the GMAT routinely expects. See:
http://magoosh.com/gmat/2013/active-verbs-on-the-gmat/

Overall, this is an atrocious question. Do not spend time trying to figure out how to justify what the source purports is the OA. Do not waste any time studying this question. It has nothing to offer you if you want to succeed on the real GMAT's SC questions.

Let me know if anyone has any further questions.
Mike :-)

This question is just flawed and wastage of time. How can they can't use "which" without comma.

Frankly speaking, I am not convinced with the OA.

I am doubtful about the usage of "which" here. "which" either comes with a comma or preposition, none of the situation is available here.

What is the antecedent of "which"? Salmon oil or Omega sources?

Please clear my doubts.

Hi Mike,
Though I also think that the question is a bit wayward, I just wanted to clear my doubt. While attempting, I marked option (b) as I thought that 'which refers to 'sources' and thus, the right verb will be 'support'. Also, there was just one option with 'promote' complying with the no of the subject. Am I right in deducing this. Is there any difference created by using 'as well as' here. Is the option wrong because its using 'as well as'.
Please elaborate on it.
Thanks a lot in advance. :-D

Hi Mike,

To decide on what should the modifier be acting on , I would like you to verify the logic I used - What I am not able to understand is how could a source (of Omega-3) support immunity and promote something. Salmon oil is source of Omega-3 by virtue of which salmon as a whole is a source, but we can't say salmon provides immunity or for that matter support something. It has to be its oil or its flesh. Just a thought . If we build on this logic my answer would be 'A'.

Dear FarhanSabkaBhai,
My friend, as a general rule, it is not worth spending a great deal of time trying to figure out low-quality questions. Such efforts are not going to get you closer to GMAT success. I would recommend focusing all your efforts on high-quality questions only. Here's a high quality question:
Snow leopards

Does this make sense?
Mike :-)
