49The following appeared in a letter to the editor of a newsletter on health issues.

"For the past decade, most health experts have advised teenagers to avoid eating greasy foods in order to prevent acne and related skin conditions, but the number of teenagers who sought medical help for these skin problems has actually risen over the same period. In a recent study, teenagers who avoided greasy foods for a month reported approximately as many outbreaks of acne and related skin conditions as did those who ate an average of two servings of greasy food per day. Such data indicate that eating greasy foods is unlikely to be a cause of acne and related skin conditions. Therefore, health experts should no longer recommend that people avoid such foods."

1、不能得出结论eating greasy foods is unlikely to be a cause of acne and related skin conditions：
a、the past decade，医生建议了，teenager不一定采取了这个意见，即使采取了可能还有其他原因导致skin problems；
b、十年时间太长，可能对greasy food进行了升级；人们的体质可能整体提高，受其影响可忽略
c、a month时间太短，不足以证明；吃了greasy的孩子和没吃的孩子，除此差别以外，还有许多其他的可能因素：前者抵抗力不如后者；前者还吃了其它可致acne的食品或药品
2、也不能判定health experts should no longer recommend that people avoid such foods
a、即使eating greasy foods不导致skin problems，也还有其它不良影响的可能，还有待进步一研究验证

A. The arguer has committed a fallacy of "After this, because of ths." That the performance of the maintenance crews of the automobile racing industry has improved markedly may be due to other factors.

B. The arguer has committed a fallacy of false analogy. There are many differences between automobile industry and airline industry.

C. It is grounlessly to say that sending the maintenance staff to the seminar will surely bring in greator customer satisfaction and profit of the airline company.
