organizations themselves assumed responsibility for establishing and enforcing their own standards and regulations.”

The following appeared in a memorandum written by the assistant manager of a store that sells gourmet food items from various
countries.
“A local wine store made an interesting discovery last month: it sold more French than Italian wine on days when it played
recordings of French accordion music, but it sold more Italian than French wine on days when Italian songs were played.
Therefore, I recommend that we put food specialties from one particular country on sale for a week at a time and play only music
from that country while the sale is going on. By this means we will increase our profits in the same way that the wine store did,
and we will be able to predict more precisely what items we should stock at any given time.”
Discuss how well reasoned . . . etc.

感想:
数学机警一定要看,感觉当月机警最有用,大家千万别学我:GMAT考试数学最痛苦的事情不是没有碰到机警,而是瞥了一眼就去考试了,靠的时候真的遇见它,最要命的是不会做,于是闭上眼睛选了一个confirm后出来一道巨简单的题问你:孩子,你来考试交钱了吗? Faint!!!
Verbal几部分最好均衡发展,不要偏科,我语法不好,ETS用语法狂扁我
ETS的风格真的是又臭又长,建议早些在机上练习
偶Verbal后半部分遇到boldface了,证明boldface确实不一定是高分的标志
