The recent decline in the value of the dollar was triggered by a prediction of slower economic growth in the coming year. But that prediction would not have adversely affected the dollar had it not been for the government's huge budget deficit, which must therefore be decreased to prevent future currency declines.
Which of the following, if true, would most seriously weaken the conclusion about how to prevent future currency declines?
(A) The government has made little attempt to reduce the budget deficit.
(B) The budget deficit has not caused a slowdown in economic growth.
(C) The value of the dollar declined several times in the year prior to the recent prediction of slower economic growth.
(D) Before there was a large budget deficit, predictions of slower economic growth frequently caused declines in the dollar's value.
(E) When there is a large budget deficit, other events in addition to predictions of slower economic growth sometimes trigger declines in currency value.
题目都看不是很懂...
答案是A嘛
原文观点逻辑链：在政府预算赤字的情况下 + 对经济发展缓慢的预测=》美圆贬值，所以原文认为应降低预算赤字来保护美圆贬值
综上所述：原文结论认为“预算赤字”是因，“美圆贬值”是果
原文观点为因果关系，削弱因果关系一共四种手段，看选项：
A）与削弱因果关系无关
B）未涉及原文结论中的因果关系
C）未涉及原文结论中的因果关系
D）正确答案，削弱方法为四种手段中的一种：无因有果
E）未削弱原文结论中的因果关系
