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.

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
