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.
前提：X国和Y国是一样的气候，但是X国和Y国农业产量不同（X国下降，Y国上升）
结论：判断X国农业产量下降的原因不是气候，而是高度集中的中央经济
果因题求削弱：
中央经济影响农业 → 相同气候X和Y农业产量不同
D选项表明，相同气候农业产量之所以不同，是因为X国和Y国作物不同导致，他因削弱。
错选B，因为D更加直接！
