75.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.
答案为何是D啊？作者: saintaa 时间: 2012-10-18 06:22
恩，题目说，一个条件是，an over centralized economy影响了 country X 比较贫弱的农业产能。假如其他条件equal(same climatic condition)，结论：Y的农业产能上升，X的下降。
题目要求削弱，那么也就是找一个不是an over centralized economy 的原因导致就可以了。答案D说的是另外一个条件，也就是crops的品种问题。所以可以削弱以上结论。
如果是support／strengthen的话，那就要找一个是over centralized的这个因素导致Y的农业产能上升的咯作者: henryest 时间: 2012-10-19 06:31
