GMATNinjaI have a slightly different perspective on option E! Yes! Option E that none have struggled eliminating!  (E) The species of insect that has infested cotton plants has never been known to attack soybean plants. All these people grew soybeans all these years. So they do not really know if their land has insects that are known to attack cotton. So according to option E, the insects that attack cotton and soy are not the same. So maybe the insects might attack the cotton because it is something common there? I guess I am sliding into the "if/maybe" dimension again?

AlN wrote: I am stillnot able to understand why Option C is wrong The plan is to stop producing cotton, and start producing soybeans. Therefore, anything that makes cotton less attractive will only strengthen the plan. This is what C does, by telling us the price for cotton hasn't gone up. So C strengthens, not weakens, the plan.

AlN wrote: I am stillnot able to understand why Option C is wrong Another take on C - what C is trying to do is suggest that without a sharp increase in demand, then the conclusion that "cotton will increase their income significantly" is invalid. But note that there are two factors in classic pricing: supply and demand. And the first sentence of the stimulus shows us that supply is down *and* even more importantly that prices are way up ("dramatic increases in the price"). So we don't need a sharp increase in demand like C might make us think - we already know that the price is up. And note that the conclusion even says "at least in the next several years," suggesting that we don't need this shortened supply to last forever or demand to kick up sharply - the conclusion is limited to this time frame in which we know that the price is up. 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.
(C) In the past several years, there has been no sharp increase in the demand for cotton and for goods made out of cotton.

So maybe the insects might attack the cotton because it is something common there? I guess I am sliding into the "if/maybe" dimension again? Let's stay focused on the conclusion we're given, then ask whether choice (E) weakens that specific conclusion. We know that the plan is for soybean farmers to cease growing soybeans and begin raising cotton instead. This plan will "increase [the farmers'] income significantly" by taking advantage of the high price of cotton. The correct answer choice is the one that most seriously weakens the plan's chance of success.Answer choice (E) states: Quote: The species of insect that has infested cotton plants has never been known to attack soybean plants. This tells us that soybean plants have never been attacked by the insects that infested the cotton plants. Therefore, it's unlikely that this insect infestation will affect soybean plants in the same way it has affected cotton plants. So what? This information does not weaken the plan's chance of success, because it does not change the evidence that the farmers used to justify their plan in the first place (the dramatically high price of cotton and the stable price of soybeans). If anything, this choice reinforces why we expect the price of soybeans to remain stable. As for your analysis: yes, you're sliding into "if/maybe" here.  Let's clarify. The passage states that the insect infestation occurred in "certain cotton-growing regions of the world." Answer choice (E) does not provide any evidence that Ortovia is in one of those regions. Also, the fact that soybean plants are not attacked by the same species that infested cotton plants does not provide any evidence that this species does live in Ortovia. Therefore, we cannot infer that the insects are present based on the information in the answer choice. On the other hand, the information provided by answer choice (B) directly undermines the plan by providing a reason to doubt that the cotton infestation will continue -- consequently lowering expectations that the dramatic increases in the price of cotton will last. So (B) is a much better option than (E). I hope that helps!

What's wrong with my explanation? I remmeber seeing plenty of questions where correct answer wasn't a probability of some even happening! Hi infymys The idea of the question is supply of cotton decreases ---> prices of cotton increase --> more profits for growers of cotton. Let analyze B and C B. Tests of a newly developed, inexpensive pesticide have shown it to be both environmentally safe and effective against the insects that have infected the cotton crops. Correct. B clearly says the new pesticide is effectively against the insects --> Supply of cotton will increase --> price of cotton will reduce. Your thought is whether the pesticide is used right? You infer too far. We can't infer that the farmers don't know how to use the new pesticide properly. You should keep in mind that "weaken" is not "destroy". Even the answer weakens 1% of the conclusion, the answer DOES weaken the conclusion and is correct. It does not have to destroy (weaken 100%) the conclusion. 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. C just says demand does not increase. Price will increase if the supply decreases while demand stay the same! Let imagine: Before: Demand = 100, Supply = 100 ==> D & S meet each other. After: Demand = 100 (No increase!), but Supply reduces to 50 --> Clearly price will increase. Thus, C is wrong. Hope it helps. The supply has decreased because the insect infestations have reduced the yields, yeah?

Which of the following, if true, most seriously weakens the plan’s chances for success? P1: Cotton prices are up P2: Soybean prices are stable C1: Price of cotton will remain high over several years, so they will increase their income significantly by growing it (A) The cost of raising soybeans has increased significantly over the past several years and is expected to continue to climb.Opposite, actually strengthens somewhat. (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.
Gives an alternate reason why this plan wouldn't work. Presumably the pesticide will be used and production will return to normal levels, lowering the price. (C) In the past several years, there has been no sharp increase in the demand for cotton and for goods made out of cotton.Doesn't help weaken, if demand is equal to prior levels then there is still a gap in the supply needed to fill it. (D) Few consumers would be willing to pay significantly higher prices for cotton goods than they are now paying.Completely out of scope. (E) The species of insect that has infested cotton plants has never been known to attack soybean plants.Opposite, actually strengthens.

Plan: cease growing Soy, grow cotton to take advantage of high price of cotton to increase income significantly p1: inset infestations caused dramatic increases in price of cotton on world market p1:price soybeans remain stable
Weaken chance for success: A - Incorrect - Increase in Soy doesn't weaken chance for success of Cotton B - (potentially - could alleviate problem causing prices to be so high) C - Incorrect- no sharp increase doesn't impact current high price of Cotton D - Incorrect - they are currently paying 'high' prices, and the plan doesn't say anything about charging "higher" amounts E - Incorrect - Doesn't impact the plan to grow cotton, it just solidifies the case that Soy is stable
