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?
对于B你想错了 因为无论如何 基因工程的crop比普通的要更耐虫害,原文中已经表明它所需的杀虫剂少很多:farmers planting them can use far less pesticide。因此,不管是不是原来使用的杀虫剂相对于所应该使用的过量,基因工程的crop在杀虫剂方面的花费都比普通的少。因此就这点来说,基因工程的crop更有利。
