Day 81 As a result of numerous complaints of dizziness and nausea on the part of consumers of Promofoods tuna, the company requested that eight million cans of its tuna be returned for testing

The following appeared in a business magazine.

“As a result of numerous complaints of dizziness and nausea on the part of consumers of Promofoods tuna, the company requested that eight million cans of its tuna be returned for testing. Promofoods concluded that the canned tuna did not, after all, pose a health risk. This conclusion is based on tests performed on samples of the recalled cans by chemists from Promofoods; the chemists found that of the eight food chemicals most commonly blamed for causing symptoms of dizziness and nausea, five were not found in any of the tested cans. The chemists did find small amounts of the three remaining suspected chemicals but pointed out that these occur naturally in all canned foods.”

Write a response in which you discuss what questions would need to be addressed in order to decide whether the conclusion and the argument on which it is based are reasonable. Be sure to explain how the answers to the questions would help to evaluate the conclusion.

五问：

（1）“As a result of numerous complaints of dizziness and nausea on the part of consumers of Promofoods tuna, the company requested that eight million cans of its tuna be returned for testing”和“the chemists found that of the eight food chemicals most commonly blamed for causing symptoms of dizziness and nausea, five were not found in any of the tested cans. The chemists did find small amounts of the three remaining suspected chemicals but pointed out that these occur naturally in all canned foods”是事实，“Promofoods concluded that the canned tuna did not, after all, pose a health risk”是结论，值得反驳吗？

（2）由 Promofoods 公司自己做的检测，是否可能不客观？比如：这些化学家为了避免被追究责任，而得出了一个更有利于自己和本公司的结论。

（3）Promofoods公司的化学家们仅检查了被召回的罐头中的一部分样品，原文中有没有给出这部分样品的选择标准？你能否想到样品选择方面可能会出现的问题？样品选取是否科学？另外五种未发现的化学品还是有可能存在于未被抽查的或是已售的罐头里。

（4）常见的将会产生不良影响的八种食品化学成分，是否已经涵盖了所有应该被检测的范围？换句话说，Promofoods公司的产品中是否可能含有并不常见的、会导致人们头晕和恶心的成分呢？

（5）对于三种被检测到的可能导致不良反应的化学品，在原文的论述过程中是否给出了其含量多少的概念？在其他罐头中也存在的这三种可能导致不良反应的化学品，其含量也和被抽查的罐头一样吗？在讨论化学品时，有和无是一个维度，含量多少以及质量大小又是另一个维度。
