The recommendation endorsed in this argument is that in order to increase sales we should fortify our Wheat-O cereal with Soy protein. The reasons cited are that in one recent survey, subjects who ate soybeans at least five times per week had significant lower cholesterol levels than who do not.However, the author's argument relies on a series of unsubstantiated assumptions, and is therefore unpersuasive as it stands.
This memo lacks sufficient information about how the study was conducted to determine what conclusions , if any , can be drawn from it. Unless all other conditions potentially affecting cholesterol level remained constant during the study, and unless the study included a statistically significant number of participants , any conclusion from the study are simple unreliable. Moreover, perhaps the study's subjects were unrepresentative of the overall population---in terms of other traits and habits that might affect the cholesterol levels. It is entirely possible, for instance, that a disportionate number of subjects that are quite young and healthy in the groups of people who ate soybean five times a week. Unless the speaker can substantiate this assumption, he can not justifiably draw any general inference about dental patients.\
The result rests on the assumption that this strategy will suffice to ensure the profit of our company and the improvement of the health of our consumer. Yet this need not be the case. Whether we can gain the goals , however depen on whether those who are concerned about their health will have interest in our products. The author ignores the possibility that the the consumers are not used to the taste of our new version of Wheat-O. Even assuming that the consumer are satisfied with the product, whether we can gain profit is not quite certain . It is entirely possible that the expense of the product increase which prevent us from gaining profits. Without considering and eliminating these and other possiblilities the president cannot rely on the simple survey to bolster the recommendation.
The author unfairly euqate soy protein with soybeans, which are not quite the same , and thus ignore the possibility that it is perhaps other things in the soy beans that have effect on the low level of cholesterol. Therefore the author can not convincingly conclude that we can improve the health of our consumer.
To sum up, the evidence cited in the argumetn is vague and incomplete, thus does not lend strong support to the conclusion that the arguer maintains. To better evaluate this argument, we need more information concerning the health conditions, the age,the occupations of the subjects. Further more the arguer would have to find out the interest of the consumer and have a thoughtful consideration about the relationship between the expense and revenue.
