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?

	The government has made little attempt to reduce the budget deficit.
	The budget deficit has not caused a slowdown in economic growth.
	The value of the dollar declined several times in the year prior to the recent prediction of slower economic growth.
	Before there was a large budget deficit, predictions of slower economic growth frequently caused declines in the dollar's value.
	When there is a large budget deficit, other events in addition to predictions of slower economic growth sometimes trigger declines in currency value.

问题：
1、But that prediction would not have adversely affected the dollar had it not been for the government's huge budget deficit,这句话本身读的就很晕，有哪位同学能给讲一讲这句话的语法？
2、我选的是A，首先是因为原文读的很晕，所以选了一个驳斥原文中提到的deficit说法的，就是说压根政府就没打算降低赤字来驳斥观点。正确答案是D，我就没有搞懂为什么是D。哪位同学能帮我吧这几个选项分析一下，谢谢啦！祝各位上7！

But that prediction would not have adversely affected the dollar had it not been for the government's huge budget deficit,
=it had not been for the government's huge budget deficit that prediction would not have adversely affected the dollar

这里是个虚拟语气的假设，简单点说就是 如果没有国家巨大的预算赤字，这个prediction不会有这么负面的影响力
也就是说： budget deficit + prediction->dollar value decline
选项只要证明，在不受budget deficit 影响的情况下，就可以影响dollar value就行。

感谢楼上二位同学的讲解，这道题主要是被那个奇怪的倒装句子弄晕了。现在明白点儿了，非常感谢~
