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，请问是怎么推知adequate solution 和required solution 的呢？文中没有意思涉及到adequate solution 吧？

文中说这是一些可行的方案，但结论变成我们只有采用才可以解决，把足以解决问题的方式当作唯一解决问题的方式了

解释一下就是：注意结论中only if 这个词表示必要条件。
solve the problem -> adopt the plan
而原题中是：
adopt the plan -> solve the problem
