[求助]大全5-9实在理解不了，请NN解

如下： 

9.     Which of the following, if true, is the best criticism of the author’s argument concerning why poverty statistics cannot properly be used to show the effects of problems in the labor market?

(A) A short-term increase in the number of those in poverty can indicate a shortage of jobs because the basic number of those unable to accept employment remains approximately constant.

(B) For those who are in poverty as a result of joblessness, there are social programs available that provide a minimum standard of living.

(C) Poverty statistics do not consistently agree with earnings statistics, when each is taken as a measure of hardship resulting from unemployment.

(D) The elderly and handicapped categories include many who previously were employed in the labor market.（A）

(E) Since the labor market is global in nature, poor workers in one country are competing with poor workers in another with respect to the level of wages and the existence of jobs.

正确答案为A。俺就没有明白A的逻辑意思。说实在的我觉得C更好。

因为题目中的criticism 和cannot双重否定的意思就等于说poverty statistics 是labor market的指标。

而C真好说明，光看收入不行，要看整体家庭情况，所以财产更好。

而C真好说明，光看收入不行，要看整体家庭情况，所以财产更好。

这道题问选项中哪个可以驳斥作者的主要观点。A选项的意思是，短期的贫困人口数量增加暗示了工作职位的减少，因为没有能力工作的人口总数基本保持不变。这就说明统计数据是基本正确反映了劳动力市场问题的——贫困人口数增加反映失业人口增加，于是反映了工作职位的减少。

个人理解，不知对不对，请nn做答！

这是作者的观点

As a result of such contradictory evidence, it is uncertain whether those suffering seriously as a result of labor market problems number in the hundreds of thousands or the tens of millions, and, hence, whether high levels of joblessness can be tolerated or must be countered by job creation and economic stimulus.

A有效的驳斥了这个观点
