prep1-49新问？（好像是逻辑题中比较少见的削弱）

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.

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
