In this argument, the author concludes that if a business wants to prosper, it should hire only people who need less than 6 hours of sleep per night. The reasons are the recent study of average number of hours people sleep; they found that those people need no more than 6 hours of sleep per night had higher profit margins and faster growth. While these assumptions, according to the author, seem not sound enough to make the conclusion.

Initially, the author assumes that those 300 male and female who involved in this study are representative. They were all picked up by random, not just the people who they are familiar with or live in a narrow area. Selecting samples are significant when doing a survey. Once the samples of the sample survey are not typical enough, the survey is meaningless. In addition, the ratio of the male and female is also an important factor to find the number of sleep hour and possibility to success. We all know that different job need different ratio of male and female, if the author didn't do a scientific survey about that, the credibility of this study can be rather slow.

Then considering the statement that those whose executives reported needing no more than 6 hours of sleep per night had higher profit margins and faster growth, which shows that the success of these firms is due to people work there have no more than 6 hours. Are there other factors help the firms gain higher profit? Absolutely there are. Think about that, if the industry generally appears prosperously, they have to spend more time accomplishing project. How can we say it is the number of hours advertising executives that determines the development of their firm? What's more, perhaps these firms have rules that the executives must work for certain hours, so those executives reduce their sleeping time in order to reach their goal. In that way they definitely have less sleeping hours, while their firm can get higher profit margins and faster growth. Thus, if we make this conclusion sound more reasonable, the assumption should be that good management makes them succeed.

Finally, the author says that hire people who sleep less than 6 hours per night. However, to judge a person whether he is appropriate for the job is not simply consider that. Responsibility, honest, professional skills are all the qualities people who seek for a job should have. The author simply assumes people who sleep less than 6 hours have those qualities, which is not convincing.

第二段中，如果你能具体说说这个题目中的调查如果是怎么样怎么样就会怎么怎么样就很好了，而不停留于抽象地说。感觉你的中间段落有点混乱，你主要质疑的是什么呢，最后一点感觉与你写的第二点有交叉的样子。
