No, it's the same cotton throughout the passage -- the bioengineered cotton.

GMATNinja, Hi
I do not quite understand why option E is not relevant.
If another insecticide can be used to control the Bollworms, then that proves that they have become resistant to the cotton's insecticide. And thus the 1st explanation of the problem, which is insecticide resistance holds true.
And hence, would help reject the other explanation, thus helps evaluate the argument.

Plantings of cotton bioengineered to produce its own insecticide against bollworms, a major cause of crop failure, sustained little bollworm damage until this year. This year the plantings are being seriously damaged by bollworms. Bollworms, however, are not necessarily developing resistance to the cotton's insecticide. Bollworms breed on corn, and last year more corn than usual was planted throughout cotton-growing regions. So it is likely that the cotton is simply being overwhelmed by corn-bred bollworms.
Hey, people! Let’s get into this. The passage talks about a crop that has been artificially altered to make a poison against a certain pest that is harmful to crops. How this altered crop took little damage - but did this year from the pest in question. That being said, it’s not a given the poison isn’t working anymore. Because the pest breeds on corn and last year there was a lot more corn planted in the same areas cotton is, the corn-bred pest is overwhelming the cotton.
Basically, the idea is because there were so many corn-bred bollworms last year, the bioengineered cotton's insecticide may simply not be enough to combat them all even though it continues to work.
In evaluating the argument, which of the following would be most useful to establish?
(B) Whether plantings of cotton that does not produce the insecticide are suffering unusually extensive damage from bollworms this year
This is the answer. If the response to this was YES, THEY DID, it would add credibility that corn-bred bollworms had bred a lot last year and spread through the cotton-growing areas this year, wreaking havoc on all the cotton there. If the response was NO, THEY DIDN'T, it would harm the argument because it's hard to to imagine corn-bred bollworms harming only bioengineered cotton and not the normal cotton present in the same region.
