22. Politician: From the time our party took office almost four years ago the number of people unemployed city-wide increased by less than 20 percent. The opposition party controlled city government during the four preceding years, and the number of unemployed city residents rose by over 20 percent. Thus, due to our leadership, fewer people now find themselves among the ranks of the unemployed, whatever the opposition may claim.
The reasoning in the politician’s argument is most vulnerable to the criticism that
(A) the claims made by the opposition are simply dismissed without being specified
(B) no evidence has been offered to show that any decline in unemployment over the past four years was uniform throughout all areas of the city
(C) the issue of how much unemployment in the city is affected by seasonal fluctuations is ignored
(D) the evidence cited in support of the conclusion actually provides more support for the denial of the conclusion
(E) the possibility has not been addressed that any increase in the number of people employed is due to programs supported by the opposition party.
两个20%有什么区别吗，我觉得都一样啊，答案是D，为什么呢？
论据是五十步笑百步，一个是失业率的增长超过了20%， 另一个是失业率的增长低于20%，不管哪个情况，失业人口都增加了。
所以论据与结论刚好相反。
I got it!
谢谢两位牛人
