prep1-49新问？（好像是逻辑题中比较少见的削弱）

wangxx2099

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?

(A) Industrial production also is declining in Country X.

(B) Whereas Country Y is landlocked, Country X has a major seaport.

(C) Both Country X and Country Y have been experiencing drought conditions.

(D) The crops that have always been grown in Country X are different from those that have always been grown in Country Y.

(E) Country X's new government instituted a centralized economy with the intention of ensuring an equitable distribution of goods.

 这个题选d，但是我总感觉怪怪的，这种削弱是不是类似于argument中的他因削弱？

GWD TN-24版本的第三套里面的题  就今天还做到过。。。很多削落是因为忽略了重要前提（即假设前提是一样的），D恰恰是说两者的前提的不一样，因而比较也就失去了意义。。。

还是不了解为啥选(D)???

还是不了解为啥选(D)???

楼主都说了 他因削弱！！

那个argument是根据同样的climate不同产量就推出产量跟climate无关，其实可以有其他原因，他们种的本身就不是同一种庄稼，产量也可以是不一样的啊。一个种小麦，一个种水稻嘛！！

其他选项都无关

An overly centralized economy, not the changes in the climate, is responsible ，后面就balabala了为啥 centralized economy 起因素。但是D 一下子就weaken了这个结论，你两个国家种的粮食都不一样，说不定是这个原因造成产量不同呢？

题目就是说有两个原因导致falling in X, rising in Y，1）就是An overly centralized economy，2）the changes in the climate,然而X和Y有相同的climate，则可说明是因为economy导致了这个结果

为了weaken这个结论，则可以找出其他原因，比如说两个国家种植不同的作物一类的
