FEIFEI-45

45. Commissioner: Budget forecasters project a revenue shortfall of a billion dollars in the coming fiscal year. Since there is no feasible way to increase the available funds, our only choice is to decrease expenditures. The plan before you outlines feasible cuts that would yield savings of a billion dollars over the coming fiscal year. We will be able to solve the problem we face, therefore, only if we adopt this plan.

This reasoning in the commissioner’s argument is flawed because this argument

(A) relies on information that is far from certain

(B) confuses being an adequate solution with being a required solution
            

(C) inappropriately relies on the opinions of experts

(D) inappropriately employs language that is vague

(E) takes for granted that there is no way to increase available funds

答案是B，我错选了E,大家帮忙分析一下如何看出adequate solution 和a required solution 的？

谢谢！！

Only if: 只有……才

A only if b：只有b发生了，a才发生。由此推断，如果a发生了，则b必已发生。但并不是只要b发生了，a就一定发生。
        只能从结果来推原因。

I will only come home if you come with me.

If only 只是if的强化形式。用法同if。

A if only B：B发生了，a就发生了。原因推结果
