答案做的对，但是对于整体的逻辑还是弄不懂，由其是第二句话该如何翻译？万分感谢！！！

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.

(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.

Convert it to If sth, Then sth structure. You would have understood the logic behind it. It's just a weird way of presenting a formal logic argument.

Premise:
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.

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.
Logic chain: Prediction adversely affected the dollar --> huge
budget deficit.
