Anoverly centralizedeconomy, notthe changesin the climate, is responsible for the poor agricultural
productionin CountryX since its new government came topower. Neighboring CountryYhasexperienced the
sameclimatic conditions, butwhileagricultural productionhas been falling in CountryX, it hasbeen rising in
CountryY.
Which of the following, if true, would most weaken the argument above?
(A) Industrial productionalso is declining in CountryX.
(B) Whereas Country Yis 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 CountryXaredifferent from those that havealways been grown
in Country Y.
(E) CountryX'snew government instituted acentralizedeconomy with the intention of ensuring an equitable
distribution of goods.

这题为什么B不对？B也在说XYcountry的不同啊

私以为是因为statement里面特别指到了“agricultural production”，所以B和D相比较起来D提到的crop这方面的不相似点比B提到的地形方面的不相似点跟“agricultural production”的结合要更紧密些。。

这是一个B，A 的题型，B是结论说poor agricultural production, A 是原因，说不是climate 而是new government，并列举了Y为例子。要削弱这argument，就攻击其原因，说就是climate 造成的，而选项中与climate和agricultural production 都有关的就是crop的种类，不同的crop受气候影响是不一样的。
而B，虽然说到了X Y 的不同，但与题目无关，闭关锁国和开放与农产品的产量、天气有关吗？倒是与政权的关系大把。。

这是一道因果关系题，原文说经济体制（因）导致了农产品下降（果），那么要削弱这种因果关系，就要说明因果关系概括错误，或者找到第三个独立的干扰因素。如D选项，农产品种类不同就是一个干扰因素，就可能使XY两国产量不用。而B选项说一个是内陆国家，一个有主要海港，这跟农作物产量似乎关系不大。
