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

正确答案是D, B的解释是The dissimilarity between Country X and Country Y that choice B describes is unlikely to explain why their trends in agricultural production have diverged.

但是我还是不懂 B 不是也是一种可能么, 为什么不能削弱? 谢谢大家~

Because it has no impact on the argument.  You need to identify the premise

and conclusion of the arugment before evaluating the answer choices.  The fact

that Country X has access to occean while Country Y does not would not

translate into any DIRECT explanation for the difference in agriculture

production without adding further assumptions.
