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?
Whether plant scientists have developed insect-resistant seeds for every crop that is currently grown commercially
Whether farmers typically use agricultural pesticides in larger amounts than is necessary to prevent crop damage.
Whether plants grown from the new genetically engineered seeds can be kept completely free of insect damage.
Whether seeds genetically engineered to produce insect-resistant crops generate significantly lower per acre crop yields than do currently used seeds.
Whether most varieties of crops currently grown commercially have greater natural resistance to insect damage than did similar varieties in the past.
我觉得B错是因为，就算农民多用了农药，那实际该用的农药也不一定就比这种新种子少，所以无法判断对顾客的吸引力
