Critical Reasoning

试题详情

题目:

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?

选项:

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 vari-eties in the past.

答案:

B

提问:

这道题,感觉B也很牵强,因为它只说了农民比爱用比所需的更多,就说明不管他们用原来的还是新的,都是只比必要的更多,是横向比较,并不能影响新的用的更少,因为虽然农民用的比必要的多,但新的必要量就更少,所以相比总量还是新的更少

提问:

感觉选项B和选项D都对评价原文有影响。原文从两个角度阐改良的品种能广泛:一是B选项是从消费者偏好少用杀虫剂的角度,二是D选项是从作物的经济性好不好的角度 为什么答案选B而不选择D 请老师帮忙解答

提问:

此题原文读起来不难,就是认为这种转基因种子未来价格会下降,同时将会使用更少的杀虫剂,而人们更喜欢杀虫剂的蔬菜,因此这种种子会前途无量。根据相关性我留下了B和D,虽然D一眼看上去和文章不相关,但读下来发现有一定道理,如果这种新种子产量小它还是不会被运用。B选项和D相比我觉得缺乏力度就选了D。网上答案是D。

提问:

我错选的D 录音里只是比较了 A 和B 能让老师讲一下B 和D 哪个更好吗? B Whether farmers typically use agricultural pesticides in larger Amounts than is necessary to prevent crop damage. 农民使用杀虫剂要更多于防虫所必要的量 D 基因设计出来的其植物具有抗虫性的种子的每亩产量要比普通种子低 我觉得 B中只是谈了一下必要的杀虫剂用量和农民实际杀虫剂用量的比较 但是还是与原文所讨论的基因种子没有关系啊? 就算是有关系,D的关系也会比B更接近原文啊?? 请老师赐教

提问:

原文说基因种子比普通种子更能抵制病虫,尽管比普通种子贵,但是价格会降下来。农民会少用杀虫剂,消费者喜欢。所以基因种子会普及化。 A科学家发展每一种抗病虫的种子种植的商业化 ,跟价格有关,留着 B杀虫剂用量的问题 无关 C新的基因种子是不是能完全防治病虫害 无关 D基因种子的产量问题 无关 E现在的crop是不是比以前天然更能防止病虫害 无关 错选了A,请老师纠正一下
