The National Farm Administration (NFA) has been concerned over the last decade with the struggles of barley growers.

Plan: In an effort to support these barley growers, two years ago, the NFA began a program of sending them, each autumn, a free special mix of fertilizer and enzymes designed to multiply barley yield, to be applied the following spring during first growth. This mix had been stunningly successful in multiplying the yield of barley in laboratory conditions.

Results: Most barley growers reported little change in their economic status over this two year period.

Further information: All barley growers received the shipments, and all used them. Weather conditions have been fair to optimal for barley growth over the past two years.

In light of the further information, which of the following, if true, does most to explain the result that followed the implementation of the plan?

A.)During these two years, most of the barley growers reported using no other fertilizer besides the special mix sent by the government.


B.)The trucks that drove the special mix from the depot in Wisconsin to the individual farms sometime took as much as 4 or 5 days.


C.)Some of the enzymes in the special mix multiply the growth of a bacteria that feeds on the young barley plants.


D.)This program was implemented at a time when more than half of barley growers nationwide were reported barely breaking even in their yearly expenses.


E.)This was the second such NFA program to aid barley growers; the first one, 14 years ago, was started with high hopes, but did little to change their situation.

It is impossible to accept the reasoning behind choice C. If it means to say that the NFA gave a program that ultimately proved inimical to barley, then the program is a flop. This is like saying FDA approved for use by expecting mothers an obstetric medicine that failed because some ingredient of the medicine had some poisonous element. In a national program, the side effects are more important than the desired effect. Yet again, no farm program will release a plan direct from the lab without testing in the farms.

Secondly the argument does not say anything about barley yield. It simply talks about the farmer’s economic lot after using the kit. What if the barley did yield well but the prices fell?

If there were a choice: the price of barley plummeted in those years due to unprecedented dumping from the neighboring countries, which had introduced similar programs.
IMHO that is the kind of paradox that would be convincing.

(I have gone through the video explanation)

C.)Some of the enzymes in the special mix multiply the growth of a bacteria that feeds on the young barley plants.

I haven't watched the video, but here is my explanation.

Argument: "Plan: In an effort to support these barley growers, two years ago, the NFA began a program of sending them, each autumn, a free special mix of fertilizer and enzymes designed to multiply barley yield, to be applied the following spring during first growth."

If there is a bacteria that feeds on the young barley plants and you give this bacteria enough time to grow in its size, then you have a problem. So by following the government advice and applying the special mix only the following spring, the bacteria is given enough time to grow and endanger the crop.

If C is the paradox, can some one explain why was barley experiment successful in lab.

To choose C as answer, we need to make strong assumption that - this so called bacteria don't grow in lab but only grow in farms - and i don't think we need to assume things for solving a paradox.

I dont agree with the OA. But i feel none of the options are relevant.

C is definitely the right answer. We're looking for some new information that could explain why the plan didn't help. If the special mix has a negative effect aside from the positive one, that could explain the problem. This doesn't require us to assume anything. Clearly, if it worked well under laboratory conditions, either the harmful bacteria was not present (entirely plausible) or something else in the laboratory conditions kept it from being a problem. In a CR problem, we don't even need to get into all that, and we certainly don't want to question the plausibility of this happening. We simply accept the given premises (the mix worked in the lab, everyone used it, but no one is better off financially). Once we accept all that, we just look for some reason for the continued trouble--the right answer could have been any source of financial trouble: invaders from another galaxy ate all the barley, every single barley grower was robbed by a team of hackers . . . it really doesn't matter what it is. We just need to know why the plan didn't leave the growers better off.

A, B, and E all require tremendous assumptions on our part. Is it bad not to use other fertilizer, or to have the mix sit in a truck for days? Perhaps, but we don't know, so it's impossible to say if this information makes any difference. D expands on what we already know--the barley growers were in financial trouble--but it does nothing to help us understand why they are no better off now that the plan has been put into action.

Hi all,
Are there obfuscators in GMAT tutors?
are there those who deliberately try to teach the students by giving them wrong lessons?
I dont get how Magoosh or whatever could say that the question above has C as an answer.
the paradox was that an improved yield did not improve economic situation.
then an option that says that worms eat the plant when they are young becomes the right answer...was the question, "WHICH OPTION DESTROYS THE FURTHER INFORMATION PROVIDED?"
:( :?: :problem: :no :no

YOUR EXPLANATIONS ARE GREAT. C destroys the conclusion that the yield got improved in real life. now there are many questions like this in gmat that lets us make some assumptions. why is this one different all of a sudden?

Nez, it's true that GMAT questions can vary slightly in the amount of real-world knowledge or common sense we have to apply to them. However, incorrect answers will usually require us to add something that simply isn't known, or to construct a whole elaborate narrative that may or may not be true. When in doubt, eliminate the most outrageous answers and then take another look at the remaining choices. If one answer seems to work but has one element that you don't feel 100% about, that should be the right choice.

Then, when you review, take the time to verify why each choice is right or wrong. If you find that you missed a problem, accept that there is something you overlooked. Don't give in to your initial instinct to say "The world has gone crazy! Everyone else is wrong!" (I know all about that.) Rather, take extra care to understand the reasoning behind the correct choice as well as the reasons to eliminate the answer you chose.

Thanks Mr Farber
It's a shame I missed something.. a word (laboratory)
I saw it in the afternoon after your comment.
But was too embarrassed to acknowledge.
The miss was a blessing in disguise.
I learnt something deep.
And it's in my error log.
"the lab effect" which limits the variables affecting the phenomenon under test.
Thanks again, DmitryFarber. Awesome name that.

If the material added to the barley fields included an enzyme that multiplied the growth of a bacteria that fed on the barley, that would explain how something involved in the plan itself had the counteractive effect of inhibiting the success of the barley plants, which in turn would explain why the barley didn't grow and why the barley growers were no better off as a result of this plan.

Hence C
