I'd have to say B. The fact that B can lead to cotton prices dropping might spell disaster for the proposal. As for D, yes, few consumers are willing to pay for higher prices for cotton, but that doesn't mean that pricing would go down. It can remain at the current high level.

Yes B is convincing.

Altough i'd choosen C initially, but i missed the point that cotton prices are already high.

I definitely fell for D. I could see why B would work, but it seems to follow a long line of causation in order to really weaken the conclusion...

I did a few practice CR today and what I now try to remember is that words in each CR question and answer are used to try to eliminate answer choices or make them the best choice.

In this question the phrase "at least over the next several years" jumped out at me.

The conclusion (by the farmers in Ortovia) is: income from cotton over several years > income from soybeans over several years.

The assumptions I considered are as follows:
*Income is dependent on the selling price of one unit of cotton
**Insects will continue in future years
***There is adequate supply of cotton if there are no insects

The premise: "Insect infestations in certain cotton-growing regions of the world have caused dramatic increases in the price of cotton on the world market"
Depends on assumption *** (adequate world supply). If there was a shortage in world production the infestation would "contribute to rising prices" not "cause" rising prices.

With this in mind we need to weaken the plan by showing some way that income will not be high for the next several years. So we need to find a reason why the farmers should stick with soybeans.

Choice B is the only choice that impacts the income in coming years.

(A) The cost of raising soybeans has increased significantly over the past several years and is expected to continue to climb.
This supports a switch to cotton, rising costs will lead to reduced income from soybeans in the future.
(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. This would weaken the conclusion, by attacking the assumption that insects will continue to affect 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.
Either outside the scope, and has no impact either way.
(D) Few consumers would be willing to pay significantly higher prices for cotton goods than they are now paying.
This says cotton price is maxed out now, there is not much potential for any additional gains. But it does not weaken the plan. If there are still insect problems, we can make money selling the cotton at current prices.
(E) The species of insect that has infested cotton plants has never been known to attack soybean plants.[/quote]
Does not give a reason why the plan will fail.

I went for C . But after reading views kinda convinced with B.

C does not tells trend about " next several years "

while B shows a bright future for forthcoming years with growing cotton.

& D talks about making more profit - " pay significantly higher prices for cotton goods than they are now paying " - BUtthe farmers can still make profit selling at current price.

Good Question.

I went with B as it is the only one which directly attacks the argument: Because of pests cotton price increased.

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.

Solution:
p1: Cotton Price Increase ( insect infection)
p2:Soyabean price stable
plan :shift of Soyabean producers --------- cotton producers( increased cotton price , quick maturity )

Cause Effect:
insect infestation ----- Price increase(cotton) ----- shift from ( Soyabean producers to cotton producers )
primary cause ------ Effect 1 ----- Final effect.

inorder to weaken, we have to attack the primary cause.

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. ( attack the final effect ) - wrong

(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. ( attack the root cause ) - Correct

(C) In the past several years, there has been no sharp increase in the demand for cotton and for goods made out of cotton. ( Demand of cotton not given - Assumption attacking the Effect1 ) - Wrong

(D) Few consumers would be willing to pay significantly higher prices for cotton goods than they are now paying.
( increasing in cotton price - attract new people in - support the plan ) - Wrong

(E) The species of insect that has infested cotton plants has never been known to attack soybean plants.
( nothing can be done with it) - wrong

This is how i perceived....

Insect infection causes price rise in cotton..

(A) The cost of raising soybeans has increased significantly over the past several years and is expected to continue to climb. - wrong , still they can increase their income

(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. -- correct .in newly developed pesticides can effective against insect .there will no price rise in Cotton price ..hence plan will fail

(C) In the past several years, there has been no sharp increase in the demand for cotton and for goods made out of cotton. - wrong .. it can still increase
(D) Few consumers would be willing to pay significantly higher prices for cotton goods than they are now paying. wrong

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

I selected C.
But now convinced that answer should be B. We are talking income from cotton over several years.

(B) is the best winner: a cure of the disease will return cotton to its previous lower price and the intended plan of reaping huge profits (as a result of increase in price) in the long run will fail.

(D) that a few customers are unwilling to absorb the extra cost (at a prohibitive rate) does not defeat the fact that its current price (dramatically increased) will result to a loss.

The problem here is not the demand, but the supply. Less supply, prices go up. The problem in C is that it doesn't consider the supply, only the demand. The demand didn't increase, but the supply fell sharply! So even with the demand on the same level, if the supply doesn't return to previous levels, the price will be good for some time.
B weakens the problem with the supply.

I picked B. 00:51 sec.

farmers are going for cotton to make more profit because cotton in some areas is affected by insects. But if insects can be killed and will affect cotton supply then, farmers cant make more profit.
