Plant scientists have been able to genetically engineer vegetable seeds to produce crops that are highly resistant to insect damage. 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?
(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.

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.

In this kind of question you're looking for an answer choice that if is true strengthen/weakens the argument and that if is false has weakens/strengthen the argument.
Premise 1: Plant scientists have been able to genetically engineer vegetable seeds
to produce crops that are highly resistant to insect damage
Premise 2: The seeds currently cost more than conventional seeds, their cost is
likely to decline
Premise 3: farmers planting them can use far less pesticide
Premise 4: most consumers prefer vegetables grown with less pesticide
Conclusion : their use is likely to become the norm
The author provides all the evidence to support that the use of the seeds will become a norm
A. Whether plant scientists have developed insect-resistant seeds for every crop that is currently grown commercially
If this is false nothing hampers that the seeds become the norm.
If this is true more seeds will become the norm.
A is out.
B. Whether farmers typically use agricultural pesticides in larger amounts than is necessary to prevent crop damage.
if this is true with the new seeds farmers will need to put less pesticides; the amount decreases
if this is false with the new seeds farmers will need to put less pesticides; the amount decreases even in a greater proportion.
The effect is the same so B is out.
C. Whether plants grown from the new genetically engineered seeds can be kept completely free of insect damage.
if this is true, this strengthens the argument
if this is false, we do not whether the current seeds are completely free of damage (in principle they are not) so no effect
D. Whether seeds genetically engineered to produce insect-resistant crops generate significantly lower per acre crop yields than do currently used seeds.
If this is true perhaps the farmers will want to continue use the current seeds because they produce greater crop per acre
if this is false the argument is strengthen because farmers will want to use the new seeds.
Correct. Two different effects
E. Whether most varieties of crops currently grown commercially have greater natural resistance to insect damage than did similar varieties
in the past.
This does not address the new seeds so is irrelevant.

) so we got a weakner...and if it's false then GEV seeds are going to be NORM (due to various Pros mentioned in the stimulus)...so we got a strengthener. Therefore, this option clears the variance test with flying colors
