Therefore, for crops for which these seeds can be developed, their use is likely to become the norm.

Which of the following would be most useful to know in evaluating the argument above?

A. Whether plant scientists have developed insect-resistant seeds for every crop that is currently grown commercially

B. Whether farmers typically use agricultural pesticides in larger amounts than is necessary to prevent crop damage

C. Whether plants grown from the new genetically engineered seeds can be kept completely free of insect damage

D. Whether seeds genetically engineered to produce insect-resistant crops generate significantly lower per acre crop yields than do currently used seeds

E. Whether most varieties of crops currently grown commercially have greater natural resistance to insect damage than did similar varieties in the past

Thanks.

Premise: Plant scientists have been able to genetically engineer vegetable seeds to produce crops that are highly resistant to insect damage and at present they are costly, but the costs will reduce in future:
Conclusion: These seeds will ve vastly used in the future.

We need to evaluate this conclusion. If we ask questions such as the yield of the seeds or the life of the crops etc. we can determine whether more farmers will use the seeds.
Option D asks the same question about the yield. If the new seeds produce low crops, then farmers might not use them

Does this help?

Thank you, OptimusPrepJanielle,

I chose B because I attacked wrong target (the validity of the evidence) rather than focus on the conclusion.

One more question, what should we do when meet an Evaluate The Argument? Pre-think a potential questions? Find a flaw in the reasoning? Or just start to go through 5 answer choices?

Thank you very much

Pre thinking is always the best way to go forward in CR.
It gives you a direction in which you should think to solve the question.

Hi OptimusPrepJanielle /chetan2u ,

I am not convinced with the solution-
IMO-B

Plant scientists have been able to produce crops that are highly resistant to insect damage. -- We call these new crops s Geneticlly engineer seeds

Positives of this crop- Highly resistant to insect damage
Grown with less pesticide.

Negatives- It is expensive but the good thing is the cost will soon decline

Conclusion- Therefore, for crops for which these seeds can be developed, their use is likely to become the norm.
Or we can say that the conclusion says that the use of enetically engineer vegetable seeds will become NORM.

Why it will become norm..?? Because it uses less pesticide and people prefer this.

Suppose there are two products in the market Apple 1 (Ordinary product)
Apple2 ( New product)
Currently Apple2 is expensive but its cost will decline.
So,after sometime we can say both have same price-

I conclude that Apple2 will soon become NORM.
Why Do I conclude this..
My reasoning behind this is-- Farmers use 2 bottle of PESTICIDE while producing Apple1
On the other hand, Farmers use 1 bottle of PESTICIDE while producing Apple2.
And consumers prefer products grown with less pesticide.

Although farmers require 1 bottle of PESTICIDE while producing Apple2 but they use 2 bottle of PESTICIDE.
So, I can't say wether consumer will prefer Apple2 over Apple1.

Hence, IMO-B

Can you please assist..where is my reasoning wrong...??

Thanks

Hi OptimusPrepJanielle / chetan2u ,

Please share our opinion. Whats wrong in my reasoning..?
Why can't B be the answer.

Hi PrakharGMAT,
since you are looing at B, let me tell you Why it should not be the answer..

Quote:
B. Whether farmers typically use agricultural pesticides in larger amounts than is necessary to prevent crop damage...

Yes, you are correct that they will use excess pesticides. But if he is used to using larger amounts, it was existing earlier too and now also..
AND when you read the choice, the stress in the option should be on THAN IS NECESSARY...

this means earlier if he required 100 kgs for a specific area, he was using 120 kgs....
Now ONLY 10 kgs is necessary, he will use 12 kgs..

Still it will be lesser than previous times and people will prefer it..

Yes, if the choice said -- Whether farmers typically use same amount of agricultural pesticides to prevent crop damage irrespective of type of seeds...
This coud have been a valid answer

Responding to a pm:

Premises:
- Genetically modified vegetable seeds are highly resistant to insect damage.
- They cost more but the cost is likely to decline.
- They need far less pesticide, and most consumers prefer that.

Conclusion: for crops for which these seeds can be developed, their use is likely to become the norm.

A. Whether plant scientists have developed insect-resistant seeds for every crop that is currently grown commercially

Out of scope. The argument clearly discusses only "for crops for which these seeds can be developed". Every crop is not our concern.

B. Whether farmers typically use agricultural pesticides in larger amounts than is necessary to prevent crop damage

This doesn't matter since it will be the same in either case.
GM crops need much less pesticide than do regular crops. Say, GM crops need only 20 kg per acre while regular crops need 100 kg per acre. If farmers do use more pesticides than is necessary, they will use perhaps 110 kg in case of regular crops and 25 kg in case of GM crops. But GM crops will need much less so anyway they will use less than the amount they use in case of regular crops.
If the farmers use only that much pesticide as is necessary, then too they will use much less pesticide in case of GM crops.
So all in all, GM crops are a better deal than regular crops so evaluating this point wouldn't help us judge whether GM crops will be the norm.

C. Whether plants grown from the new genetically engineered seeds can be kept completely free of insect damage

They are much more resistant to insect damage. Whether they will make the crops completely insect-proof, we don't know. It doesn't matter either. Since they are far more resistant, they should become the norm.

D. Whether seeds genetically engineered to produce insect-resistant crops generate significantly lower per acre crop yields than do currently used seeds

The argument discusses the positives of the GM seeds and declares that they will become the norm. But it will be useful to evaluate if they have any shortcomings compared to regular seeds. If their yield is much lower, farmers are likely to not use them since they might earn less than what they earn currently. Hence, this will be useful to evaluate. This will tell us whether GM crops are likely to be the norm.

E. Whether most varieties of crops currently grown commercially have greater natural resistance to insect damage than did similar varieties in the past.

GM crops have much higher resistance as compared with regular crops. Whether the resistance of regular crops has naturally increased over time doesn't matter. GM crops are much more resistant.

Although these seeds currently cost more than conventional seeds, their cost is likely to decline. Moreover, farmers planting them can use far less pesticide, and most consumers prefer vegetables grown with less pesticide, therefore, for crops for which these seeds can be developed, their use is likely to become the norm.

which of the following would be most useful to know in evaluating the argument above?

Premise :- The New seeds with all the awsome features
Conclusion :- Will be the Norm

Assumption :- For a crop to be a norm it has to be insect resistant and no other factor comes into play

A. Whether plant scientists have developed insect-resistant seeds For every crop that is currently grown commercially :- Irrelevant, rather explicitly stated in the stimuli
B. Whether farmers typically use agricultural pesticides in larger Amounts than is necessary to prevent crop damage.:- Irrelevant
C. Whether plants grown from the new genetically engineered seeds Can be kept completely free of insect damage. :- Irrelevant
D. Whether seeds genetically engineered to produce insect-resistant crops generate significantly lower per acre crop yields than do currently used seeds. :- Yes the introduction of new factor, saying Yes will destroy the stimuli and saying no it will strengthen it
E. Whether most varieties of crops currently grown commercially have Greater natural resistance to insect damage than did similar varieties in the past. Irrelevant

OA after explanations

Here is what I have been using for these question types(Evaluating the argument).
Choose an question(option) whose one extreme answer will strengthen the argument and the other extreme answer will weaken the argument.

Hope this helps.

We have to attack whether GM will become a norm or not. So D is the best.

Moreover, farmers planting them can use far less pesticide => SO we know that using GM will reduce amount of pesticides required. so whether farmers use more or less, GM will use less pesticides anyways.

Sorry if I'm a little slow. I initially chose B. If farmers typically use pesticides in larger amounts, they can reduce usage, and hence genetic seeds will not become the norm. if they typically DO NOT use pesticides in larger amounts, they cannot reduce pesticides, and hence genetic seeds WILL become the norm, since farmers will gravitate toward insect resistant crops

Where am I going wrong?

IMO D is true : If the new seeds generate significantly low crop yield, then it may become difficult to become a norm.

The argument was easy but the options were way too confusing. But i later realized that option B is no where in relation with the argument . The argument just says that there is little pesticide used for the genetically engineering vegetable seeds , so that's why option B is incorrect. Therefore option D is correct .
