T-3-Q3 急啊 和 OG69有冲突

T-3-Q3.

Scientists have made genetic modifications to cotton to increase its resistance to insect pests. According to farmers’ report, the amount of insecticide needed per acre to control insect pests was only slightly lower for those who tried the modified seed than for those who did not. Therefore, si farmers economically.

 

Which of the following would it be most useful to know in order to evaluate the argument?nce the modified seed costs more than ordinary seed without producing yields of higher market value, switching to the modified seed would be unlikely to benefit most cotton

 

1. Whether farmers who tried the modified cotton seed had ever tried growing other crops from genetically modified seed.

2. Whether the insecticides typically used on ordinary cotton tend to be more expensive than insecticides typically used on other crops.

3. Whether for most farms who grow cotton it is their primary crop

4. Whether the farmers who have tried the modified seed planted as many acres of cotton, on average, as farmers using the ordinary seed did.

5. Whether most of the farmers who tried the modified seed did so because they had previously had to use exceptionally large quantities of insecticide.

 OG上原题，但它的答案是D，和这的不同，但肯定不是B（是该题答案），因为OG上有一样的选项但没选这项。  求助啊

没明白LZ意思，这道题的答案是B啊 怎么了 以前是一道争议题，在B和E之间的，B主要是说他的经济优势，E说他以前用量大，意思是对环境的破坏方面，但是最后背景信息给的结论是他有经济优势，所以选B，怎么了？

B：可是文中没有提到other crops 吧。。不知道算不算是无关选项哦？

B提到OTHER CROPS，无关比较

D是评价REPORT的可信度，是唯一的有关项，正确答案。

D是什么意思啊？ 我怎么越看越糊涂啊~
D是不是说 使用转基因种子的农民是否与使用非转基因种子的农民种植的土地一样多 的意思么？
与题设中的结论-- 转为使用转基因的种子并不会给大部分农民带来利益-- 有什么关系么？

这题到底选什么哦

og12上面69这道题目，D是答案，但是D的内容和这里的完全不一样，这里的D说种改进种子的棉花和种普通种子的棉花耕地面积一样，这个如何能够评价？我觉得是无关的！而OG上面的D的内容是:种改进版的是不是用了过多的农药。这个是答案没有问题，评价了原文的结论。如果过多了，那么结论说不怎么经济的结论是错的，因为农药用了不必要的剂量~
