TOPIC: ARGUMENT84 - The following appeared in a memo written by the head of the Gorham School.

"Our school cafeteria should make changes in the lunches that it serves in order to improve the health of our students. Several teachers and I have observed that students who eat these meals tend to eat the main course and the dessert, but seldom finish the vegetable portion. This pattern means that students are missing the vital nutritional benefits of fruits and vegetables, which are typically rich in vitamins and minerals. Therefore, the school cafeteria should serve larger fruit and vegetable portions along with smaller main course and dessert portions. This change will be effective because, according to research conducted at the Rose Children's Hospital, children eat the same amount of food served to them-about 55 percent, on average-no matter what the main course is."

In this argument, the speaker concludes that the schools' cafeteria should serve more fruit and less main course and desserts in order to supply students' vitamins and minerals, mainly based on the observation of the speaker and several teachers as well as a research at the Rose Children Hospital. Although this assertion seems convincing at the first glance, this evidence fails to constitute a logical statement in reasoning or provide compelling support making this argument sound and invulnerable.

In the first place, the evidence provided by several people is a small insufficient sample failing to draw a reliable conclusion. It is possible that the speaker and the teachers involved have their fixed schedule that make them always observe cafeteria's situations of some certain area and certain time, for example, of the second floor of the cafeteria which is famous for its main course or of the 1pm to 2pm when most boys choose to have meals. And at other part of the cafeteria, like the first floor, students may tend to eat the vegetable and seldom finish their course. To have a statistics reliable survey, the study's sample should be sufficient in size and representative of the overall population.

Even if we concede that the survey is reliable, from it we cannot get the conclusion that the students are missing the vital nutritional vitamins and minerals. Firstly, students hardly finish he vegetable portion do not equals that they seldom have enough vegetable. Maybe the reason is that the cafeteria offers too much vegetable and insufficient main course and dessert. If so, the cafeteria should provide more main course and desserts rather than the vegetable. What's more, we cannot exclude other meanings by which students can get the same nutrition. A case is that the area of school teems with fruits, containing vitamins and minerals as well. So, almost every student chooses to have these cheaper and more delicious fruits to get the vital nutrition. Until the author provides further evidence to exclude all these concerns, it is unfounded to reach the conclusion involved in the argument.

The last but not the least important, even if the speaker can substantiate all of the foregoing assumptions, his assumption that mere adding the vegetable and fruit portion can effectively ensure students' nutrition is flawed. Perhaps the same measures of the hospital would be ineffective on the students' diets due to that the hospital and the cafeteria are totally two different departments. The sick children's diet has definite function to help the children recover. And the children also have desire to get well sooner and the pressure from their parents and the faculty of the hospital that force him to have a balanced diet. But in the school, the price and taste count more in students' decisions. For example, if the school adds certain portion in sum without improving the taste or cutting the price, it can hardly attract more students to have more vegetable and fruit. In short, lacking evidence that conditions on the two departments are relevantly similar, the author cannot convince me on the basis of hospital's experience that the proposed course of action would be effective for the cafeteria.

The argument for diet based on the observation and Rose Children example could provide information and somewhat help the students get balanced nutrition. Before conclusions about the measure that should add the portion of the vegetable and fruit, however, a more complete understanding of the benefits is needed. After all, some other meanings such as improving the taste of vegetable, offering more suitable dining circumstances and cutting down the price should be combined to achieve a better consequence.
