求助一道费费题

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 

谢谢帮忙。

这题选B

if A→B then A is a sufficent solution for B

only if A →B then A is a required solution for B

题干是把这两个混淆了
