RC1. Gray Marketing (3 paragraphs)

P1. Manufacturers and retailers usually consider gray marketing detrimental to their margin and profit, since gray markets snatch market share by offering lower prices.

P2. Under certain market conditions, gray marketing can benefit manufacturers and retailers. The favorable market condition is met when the customer base is distinctively segmented- i.e. the presence of a significant number of both price sensitive and price insensitive customers.

P3. In the presence of market segmentation, manufacturers and retailers can increase profits by charging higher prices to price insensitive customers while improving the quality of the service. This measure will most likely offset the loss of revenue from price sensitive customers.

Q1. What is the primary purpose of the article?

-->To explain how gray marketing can benefit the profit and margin of manufacturers and retailers.

(This answer was a close call, not very sure)

RC2.  Sea Serpent (3 Paragraphs)

Q1. Which of the following would the author most likely to agree regarding the travel guide?

--> The travel guide shares the same attitude with some writers on this topic.

RC 4 Beginning of modern science (1 or 2 paragraphs, can't recall the details)

P1. Though the prevalent view is that modern science emerged in 16-17th century, Some of the most important approaches defining the modern science or thoughts shaping the modern science could in fact be traced back to as early as 14th century.

In order for [the other party/group] to endorse either initiative, the legislation will have to increase spending on energy. Which can be inferred from this?

-->  It is impossible for both the government and [the other party/group] to endorse the job program

The RC questions I got today were remarkably harder than those in the GMAT prep.

最后简单说一下备考经历，可供背景相似的同学参考。

美国理工科PhD，考虑到市场不景气对找工作的影响，决定考GMAT，以便毕业找不到工作的情况下多一条出路。英语基础不错 ，加之临近毕业事务繁杂可供复习的时间有限，所以打算尽量提高备考效率。二月仓促间报了名，到考试四个星期。复习过程如下, 总共复习时间约40小时。

GMAT prep 模考1,2:  760/740 ，错误多为SC, 5小时

复习SC： 下载的白勇语法， 大约一天花一小时看一章， 12小时

OG: SC 120道题，2小时

RC/CR GMAT prep破解题库: 做了 题库1 的 RC/CR和题库2的RC/部分CR， 5小时

作文：看了七宗罪和一本叫800 Score的电子书，随机抽取 ISSUE/ARGUMENT各五篇练习，10小时. 今天的Argument 居然是五篇中的一篇。

GWD: 下载了所有的题，由于时间限制，只抽了其中一套Verbal，似乎是26，发现答案有很多错误。2小时

考前一天在论坛上看了一下机经， 回顾了一下语法错题，3-4 小时。

考试结果q51, v 47。Verbal错的应该还是SC，有2-3题不确定答案，CR可能也有错题，看来想切实提高SC的话还需要下大量功夫，但对我来说marginal benefit 较小，就没有刻意为之。
