老prep 2 中一道题 （题号不清楚）

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.



I would say D. The argument is saying that the slower economic growth coupled with the large budget deficit makes the dollar go down.

D weakens that by saying that it still goes down without the large budget deficit.

上面是一个老外的答案，也就是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.说的是 economic growth 和 budget deficit是一个作用，可我怎么也看不明白是什么意思？能不能帮我分析一下这句话的语法结构。我想里面可能有些固定搭配我不理解吧。

dollar后面的had it not是一个倒装的条件状语从句，是表强调。而且是虚拟语态。意思是如果.....没有发生。句子的基本结构是“if it is not for...”如果不是因为...
