45.

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.

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

感谢大侠还想问一下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.

应该是逗号前面的句子采用了省略if的倒装，分解开来的话：But that prediction would not have adversely affected the dollar , if it had not been for the government's huge budget deficit, which must therefore be decreased to prevent future currency declines.
