An overly centralized economy, not the changes in the climate, is responsible for the poor agricultural production in Country X since its new government came to power. Neighboring Country Y has experienced the same climatic conditions, but while agricultural production has been falling in Country X, it has been rising in Country Y.
Which of the following, if true, would most weaken the argument above?
Industrial production also is declining in Country X.
Whereas Country Y is landlocked, Country X has a major seaport.
Both Country X and Country Y have been experiencing drought conditions.
The crops that have always been grown in Country X are different from those that have always been grown in Country Y.
Country X's new government instituted a centralized economy with the intention of ensuring an equitable distribution of goods.
B选项和D选项同样道理吧，都是在为X国和Y国的农业产量差异找其他原因。如果Y国内陆而X国沿海，那么两国农业受同样气候的影响就会不同——比如飓风对沿海地区的影响比内陆地区大。求问B选项为什么不对呢？thx!
B也可以评估这个推理文段，也就是说，没有D的话，B肯定也对。但是在有D的时候，B和文段的相关度更差。
看似是类比推理，其实是因果推理？因为xy的天气的不变量，得出结论:经济才是农业产量下降的原因。题目需要结论，只要给出农业产量下降的另外一个原因就好。是这样吗
