GRE官方题库原题144

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.

题目翻译

去年由于有大量消费者投诉说产生了眩晕和恶心，Promofoods要求800万罐金枪鱼回收检测。Promofoods下结论说这些罐头根本不含任何有健康危害的化学物质。这一结论基于这样的事实，即Promofoods的化学家测试了回收的罐头样本，并发现8种最常见的导致眩晕和恶心症状的化学物质中，有五种都没有在任何被测试的罐头中被发现。化学家确实发现剩下三种受怀疑的化学物质在所有其他罐头食品中都存在，并指出这在所有的关头中都存在，属于正常现象。

题目分析

1. 含量低或者在其他食品中的存在，不能作为不致病的原因。第一，含量低不一定就健康，可能含有微量的成分就可能中毒;第二，存在于其他食品中不代表就无毒，可能大家都有毒，只不过该食品中含量较高，因而表现了出来。

2. 即使致病原因不在这八种物质中，这些罐头也未必健康。因为可能是罐头中除了这八种物质以外的化学成分有致病的作用。所以作者应列出其他的健康指标作为证据

3. 即使样品无毒，也未必能代表所有产品都无害。
