61. 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.


题目不是特别理解，有点不清楚，望高人指点迷津~~~

题目的意思好像是：
最近美元的贬值是 由 对明年经济增长放缓的这一预测 所引起的。 但是这一预测本来不应该对美元有着不利的影响，要不是因为政府巨大的预算赤字，所以为了防止未来的货币贬值，这一赤字必须要减少。

If it were not for the government's budget deficit, the prediction would not have devalue the dollar.

So the deficit is the necessary condition for the devaluation of the dollar.

Back to the stimulus:
Premises:
1) The devaluation of the dollar was triggered by a prediction of slower economic growth
2) If there is no government's huge budget deficit,  the prediction alone will not affect the dollar devaluation.

Conclusion: government's huge budget deficit must be decreased to prevent future currency declines

Answer (D) Before there was a large budget deficit, predictions of slower economic growth frequently caused declines in the dollar's value.

If D is true, then premise 2 is wrong since apparently the prediction alone can cause the devaluation.  So D weakens the argument and D is the anwer
