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.
选D, 没有财政赤字前，预测就经常导致减值。
但这不和原文条件相反吗？
But that prediction would not have adversely affected the dollar had it not been for the government's huge budget deficit 如果不是财政赤字的话，预测是不会对dollar有影响的。D没有财政赤字前，预测就经常导致减值 反对了这句话阿。
结论是说budget deficit, which must therefore be decreased to prevent future currency declines，即减少赤字以预防减值。
问题是：would most seriously weaken the conclusion
答案是：减少赤字不能预防减值。因为没有赤字之前，也会出现减值，即赤字和减值之间没有直接因果关系。

谢谢版主解释，可我还有一点不明白。。 But that prediction would not have adversely affected the dollar had it not been for the government's huge budget deficit的意思是不是没有财政赤字的话 prediction就没有负面影响？ 是的话，但答案说的是在赤字之前，prediction 就导致降低了，不就是有负面影响了吗？反对了前提呀。。
