Prep CR 45 求解释求逻辑推理

珍妮弗

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?

请NN们翻译一下But that prediction……future currency declines的意思，和题目的逻辑链. 最后一战，真心想跟GMAT和好。
(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.

答案选E，求解释

答案不是选D吗？
由于预计未来经济变缓，最近的货币贬值。但是如果没有政府巨大的预算赤字，预计未来经济增长变缓，不会导致未来货币贬值。
文中认为：预计+巨大的预算赤字——贬值
D项说：在没有巨大的预算赤字之前，预计经济变缓导致货币贬值。
说明：不需要巨大的预算赤字也能导致货币贬值
所以，降低预算赤字无效，削弱文章观点

不知道是不是这样？
