Plant scientists have been able to genetically engineer seeds to produce crops that are highly resistant to insect damage. Farmers planting such seeds can use much less pesticide. Although these seeds currently cost significantly more than nonengineered seeds, their cost is likely to decline. Since these seeds produce crop yields as high as those produced by nonengineered seeds, the use of genetically engineered seeds is likely to become increasingly common.
Which of the following, if true, most strengthens the argument?
A. Plant scientists have not yet developed insect-resistant seeds for all commercially grown food crops.
B. Consumers prefer to buy grains, fruits, and vegetables that have been grown using little or no pesticide.
C. Traditional methods of plant breeding have also resulted in some insect-resistant strains of plants.
D. Crops grown from seeds that are genetically engineered to produce insect resistance will still be vulnerable to other types of pests.
E. The cost of many commonly used agricultural pesticides is likely to decline as the use of genetically engineered seeds increases.
