GMAT作文AWA新题找攻击点!
The following appeared in a research paper written for an introductory economics course:
　　“For the past century,an increase in the number of residential building permits issued per month in a particular region has been a reliable indicator of coming improvements to that region’s economy.If the monthly number of residential building permits issued rises consistently for a few months,the local unemployment rate almost always falls and economic production increases.This well-established connection reveals an effective method by which a regional government can end a local economic downturn:relax regulations governing all construction so that many more building permits can be issued.”
我暂时想出来的攻击点有：1 木有考虑过多的建筑许可证带来的危害（但是具体什么危害我也举不出来例子,房价下跌?）2 过去100年有效不代表现在有效（奇葩的100年,之前的题最多10年,感觉100年就成了定理,好难攻破!）求问其他攻击点?实在是对不起大家.

答案

1.因为,每月增加的住房数量是经济增长的indicator（也就是指标）,也就是经济增长带动了住房数量的增长.但是不代表住房数量的增加就会使得经济增长.
2.如果现在的regulation其实已经超过了需求,也就是你在放宽要求,人也不会多.
3.你说每月住房数量的增长会导致当地失业率的下降和经济产量的上升.但是,你必须排除其他的因素.万一在这一阶段还有其他因素会导致失业率的下降和经济产量的上升呢,比如国家调控了财政政策啊货币政策啊.
