请问feifei logic 45

米样

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

正确答案是B，我对这个选项不是很理解啊，我做题的时候选了E，我觉得挺顺的啊，可是feifei解释说，这是前提，可是不允许前提有错吗？

我觉得跟题目的问题有关，这是一个问reasoning的题目，B is best. 如果题目文assumptions，E是一个premise. 个人看法，希望有帮助
