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 请问this plan（decrease expenditures）原本应该是一个必要条件还是一个充分条件？作者: sdcar2010 时间: 2011-7-13 01:19
