放牧与种庄稼之间的冲突,是否因为农业的增加而使得牧场的面积减少了呢文章较短,作者提出了另外的解释,说明这两者不是这种关系,用的词叫做inverse,当时没怎么理解这个词,觉得有点抽象[大牛kayx0226注释:"作者提出了另外的解释,说明这两者不是这种关系" 也没有说不是这种关系,(注意有题是说"the author provides an alternative explaination"我觉得是错误的答案)]
发现cotton的一个类似原题 麻烦确认下是不是: 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, since 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 farmers economically. Which of the following would it be most useful to know in order to evaluate the argument?
A. Whether farmers who tried the modified cotton seed had ever tried growing other crops from genetically modified seed. B. Whether the insecticides typically used on ordinary cotton tend to be more expensive than insecticides typically used on other crops. C. Whether for most farms who grow cotton it is their primary crop D. Whether the farmers who have tried the modified seed planted as many acres of cotton, on average, as farmers using the ordinary seed did. E. Whether most of the farmers who tried the modified seed did so because they had previously had to use exceptionally large quantities of insecticide.
