如果是GMAT新手,可能看到一些词会一头雾水，比如CD, OG, GWD,FEIFEI和天山分别是什么东东阿?下面我们就为大家做一个解释。一起来看看内容： feifei gmat数学是什么?
CD www.chasedream.com 是个挺牛的gmat论坛
OG official guide 官方指南
GWD guanweidong 就是管卫东,一个gmat的教师,博森的创始人,原来的新东方元老,这里GWD指的是他收录的机经题
FEIFEI 就是费费,新东方老师,编了一套费费逻辑
天山 一套备考gmat的题
好吧，现在大家知道了吧，Feifei的主要内容是逻辑，下面附上一些Feifei逻辑解析内容，供同学们参考学习：
1. Although 90 percent of the population believes itself to be well informed about health care, only 20 percent knows enough about DNA. So apparently at least 80 percent of the population does not know enough about medical concepts to make well-informed personal medical choices or to make good public policy decisions about health care.
The argument’s reasoning is questionable because the argument fails to demonstrate that
A. those people who can understand news stories about DNA are able to make well-informed personal medical choices
B. more than 20 percent of the population needs to be well informed about health carefor good public policy decisions about health care to be made
C. one’s being able to make well-informed personal medical choices ensures that one makes good public policy decisions about health care
D. an understanding of DNA is essential to making well-informed personal medical choices or to making good public policy decisions about health care
E. since 90 percent of the population believes itself to be well informed about healthcare, at least 70 percent of the population is mistaken in that belief.虽然90%的人都认为自己很懂health care，但是只有20%的人足够了解→结论：所以说 至少80%的人医疗知识根本不够，因而无法做出health care方面正确的决定
思路：这里很明显就一个gap. 为什么不懂DNA的80%就不懂医学不会做决定了呢?本题的推论错误在于以偏概全，用对DNA的了解程度来考核well informed about health care的程度。
A: 支持作者的观点 杀
B: 无关
C: 无关
D:正解
E:无关
