The correct answer is B because

(A) The cost of raising soybeans has increased significantly over the past several years and is expected to continue to climb.

is irrelevant with cotton.

(C) In the past several years, there has been no sharp increase in the demand for cotton and for goods made out of cotton.

(D) Few consumers would be willing to pay significantly higher prices for cotton goods than they are now paying.

The prices are already on the upward trend, so nullified

(E) The species of insect that has infested cotton plants has never been known to attack soybean plants.

is irrelevant.

Please give kudos if the reasoning makes sense

I am still not sure of the OA. I went with C and to me both B and C look like good choices.
The weakner has to give the farmers a reason why they should not go for Cotton.

Choice B means that the new inseciticide will stop the spoilage of cotton and ultimately support the supply, which ultimately will soften the prices and make getting into the market an unprofitable proposition.

Choice C says there hasn't been an increase in demand for Cotton or goods made of cotton.So farmers getting into the market would support the supply, again softening the prices and make getting into the market an unprofitable proposition.

The reason how the supply would increase is different for the two but the end result is similar.

this confused me. I thought the best choice was E because the farmers switching from SOY -> COTTON would face the same exact problems that cotton farmers were facing (so there wouldn't be a viable reason to switch).

I'm overthinking. the correct answer is definitely B but this was a good question.

Insect infestations in certain cotton-growing regions of the world have caused dramatic increases in the price of cotton on the world market. By contrast, the price of soybeans has long remained stable. Knowing that cotton plants mature quickly, many soybean growers in Ortovia plan to cease growing soybeans and begin raising cotton instead, thereby taking advantage of the high price of cotton to increase their income significantly, at least over the next several years.

Which of the following, if true, most seriously weakens the plan’s chances for success?

(A) The cost of raising soybeans has increased significantly over the past several years and is expected to continue to climb.
(B) Tests of a newly developed, inexpensive pesticide have shown it to be both environmentally safe and effective against the insects that have infested cotton crops.
(C) In the past several years, there has been no sharp increase in the demand for cotton and for goods made out of cotton.
(D) Few consumers would be willing to pay significantly higher prices for cotton goods than they are now paying.
(E) The species of insect that has infested cotton plants has never been known to attack soybean plants.

The whole point author is trying to drive here is that significant income growth will be seen by switching to cotton crops instead of soy. Its not much about demand. So that's D doesn't fit good.
And cotton crops are being sold for extra because insect infestations are bringing down the throughput and shooting up the prices. So if new pesticide works a mentioned in B then it will weaken plan's (Switching to Cotton for extra income instead of Soy) chances for success.

Why is C wrong..???
if there has been no demand in the past, then even after producing the cotton, what is the guarantee that cotton will be sold at high price???

Choice C says, there has been no sharp increase in the demand for cotton. That does not imply that the demand has fallen down. Soybean farmers can still make more money by selling cotton at higher prices to cater current demand.

Choice B directly attacks the conclusion. According to B, newly developed pesticide, which is inexpensive, will soon be used by cotton growers globally, resulting in increased supply of cotton, which will affect the current high prices of cotton

I came very close, i was between B & C but choice B doesn't state anything about the cost of the insecticide. This leaves a gap on the reasoning whether it could be purchased inspite of being available in the market... Wat makes my claim wrong??

Yes, B does say that the pesticide is cheap.

(C) In the past several years, there has been no sharp increase in the demand for cotton and for goods made out of cotton.
This does not weaken the argument. Even if there has been no sharp increase, the market could still be profitable enough for the new cotton growers.

Hi,

COuld you please explain why is A incorrect..??

If the prices of soyabeen were rising in the past and will continue to rise, then we can state that producing soyabeen would be more profitable.

Hi there,

I think that you have misunderstood the argument somehow. Do you mean that THE COST of growing soyabeen is rising? And therefore producing COTTON would be more profitable? (because price of soya is stable and its cost is rising?)

If that's the case, then we would have a reason to think about switching to cotton, what do you think? This for sure does not weaken the argument "switch to cotton will increase the income"; it's more likely to support the conclusion.

Hope this is what you mean

Hi,
Let me chime in.

Per choice A, cost of producing the soybeans has been increasing since couple of years. This indeed provides the reason for soybean growers to shift towards cotton growing. This choice in fact strengthens the argument.

Hope that helps.

That means.. either the demand is steady or it has fallen..!!!
So, selling cotton at higher prices(compared with the selling price of soyabean) will given them more profit...

What if the demand has fallen to a certain level, that the profits made out of it( during the high prices of cotton) were equal to that of soyabean.

I hope you are getting, what i mean to say...

10*10 => 100
5* 20 => 100...

There wont be any benefit for switching to cotton...[ I am assuming only the case when demand has decreased].

I mean this could be a scenario..

Well, I think you are too much inclined towards Choice C.

Dude, while approaching any weakening conclusion question we should understand how things work. In a CR stimulus, conclusion depends on the certain facts. These facts may be given(stated) or assumed. All these facts act as pillars and support the conclusion.

Let's take the case of our stimulus....

Fact (Given) :- Supplies of the cotton in the world market has been affected severely because of insect infestation in cotton growing region. Due to the short supplies prices of the cotton in the world market have been increased dramatically.

Fact(Given) :- The prices of soybean have been long stable

Fact(Given) :- Considering the above circumstance soybean growers in Ortovia above plan to cease soybean growing and to raise cotton instead

Conclusion :- Taking Advantage of increased price of cotton

Fact (Assumed) :- Insect infestation will not affect the cotton crop in ortovia

Fact (Assumed) :- Prices of the cotton in world market will remain be high till the cotton plants of ortovia farmers get mature.

Fact (Assumed) :- Demand for the cotton will not fall in the world market till the cotton plants of ortovia farmers get mature.

Fact (Assumed) :- Circumstance in the traditional cotton growing regions will not improve atleast till the cotton plants of ortovia farmers get mature.

Fact (Assumed) :- Cost of growing cotton in ortovia is not greater enough so as to loose the benefit the ortovia farmers got from switching to cotton.

These are only few. There can be many such assumes facts which buttress the argument. Since as per the fundamental rule of weakening we can not go against stated facts. i.e. we can not prove the premises wrong, our job is to attack these assumed facts, just as we did in above case.

After reading any CR stimulus and question, we should consider the assumed facts. Based on the assumed facts we should think about the possible answer to that question and should then approach the answer choices in attacking mindset. This way you can spot the correct answer choice with ease in most of the cases.

I will not say that this is the ideal way of solving a CR question. I would only say that this works better for me.

It is good that you are considering all aspects of the answer choice. But doing this with every answer choice ,that too with not guessing the possible answer, can be problematic in the exam.

As for your specific query about choice C, it is mentioned that there has been no sharp increase in the demand for the cotton. so it can be derived that atleast minor but steady increase was there, so no such scenario as decrease in demand exists.

Hope that helps.

Sorry for extending the discussion...

I think i missed the word "sharp"..
Too much of pre-thinking is very harmful.. We can figure out loopholes in any option...Its just that we need to weaken the argument... maybe 1% or 90%... 100% is not compulsary...

I think i went into too much deep thinking...!!!

Anyway, thanks a ton for you wonderful explanations..!!!

Had the word sharp missing in the option C, would my explanation be valid in that case???

I know what the OA is and I see why it's correct, but I can't be the only one who narrowed it down to E and B.

E: The species of insect that has infested cotton plants has never been known to attack soybean plants.

The stem talks about this bug wiping out cotton plants, but does not address whether or not the bug resides in Ortovia. If the bug eats soybean plants, and the soybeans aren't being wiped out, it stands to reason the bug is NOT in Ortovia, and therefore planting cotton is safe. If the bug does NOT feast on soybean, then it could be present, and once they plant the cotton it'll wipe it out as it has in other countries.

Again I see why B is right, but if anyone arrived at the same place I did in their rationalizing, well, just know you're not alone

Hi this is a pretty challenging question. Took me some time to appreciate the OA. I was stuck between B and D and I chose D in the test.

Here is my understanding after reading several posts. Hope you fill find it useful.

B is correct because if a new inexpensive pesticide is effective, existing cotton growers will start using it and their yield of cotton would increase (or at least return to normal). Therefore the shortage in demand will reduce and the price will stabilize. There is no opportunity for increasing revenue over the next several years as the soya farmers wish.
