Public health official: Some researchers suspect that magnetic fields from high-voltage power lines can cause health problems for people who five especially near the fines. However, this is extremely unlikely: Beyond a distance of a few feet, the strength of the magnetic fields from high-voltage power lines is less than the average strength of magnetic fields in homes that are not located near such lines.

Which of the following would it be most useful to establish in order to evaluate the public health argument?
A. Whether magnetic fields in homes that are not located near high-voltage power lines can cause health problems for the residents of those homes
B. What proportion of people who live near high-voltage power fines believe that those fines may cause health problems
C. Whether high-voltage power lines are routed near residential in urban areas
D. What specific diseases or conditions are suspected by some researchers to result from exposure to magnetic fields from high-voltage power lines
E. What is the average strength of magnetic fields in workplaces that are not located near high-voltage power lines

KEY：A

表示看不懂。。。而且还标注是easy标准的。。泪都哭了

我来了。问题主要问电线杆是否对健康有害。那个人说没有，因为外面的电线杆还没有在家里接受的辐射多呢。但 ...

同意！

D :suspected也只是怀疑而已，by some researchers没有代表性。
“某些研究者怀疑高电压电源线。。。。。results in specific diseases..”
很主观，也很片面

D中的" specific diseases or conditions are suspected by some researchers to result from exposure to magnetic fields from high-voltage power lines " 是直接攻击了论点,也就是第一句话,即通过判断"处于这样的磁场中会有什么具体病理特征",可以推出是否对健康有影响,,,,A选项攻击的是后面的解释

不过我选D的时候也感觉这个答案不够好,不如A直接,但是A的明显逻辑漏洞怎么解释呢? 即通过判断A,只有50%的特定情况可以推断出是否影响健康,,,,,而D虽然不如A直接,但可以100%得出结论.

以上是我对该题的思路,不知是否有逻辑错误,请高手指证.

同意楼上。。正确选项要和问题相关

我觉得D还是错的。因为它虽然提到文中的词语，但没有攻击文中任何一个论点。但是A它攻击了Public health official 的论证：影响健康。

我也做错了,但是发现答案A还是未能直接评判这个问题,因为题目中说的是电磁强度比家中的小...那么即便普通家中对人有影响,也不能说明电线杆的就一定有影响呀? 除非普通家中是对人没影响才能得出结论........所以我选的D

偶明白了~！多谢谢

我来了。
问题主要问电线杆是否对健康有害。
那个人说没有，因为外面的电线杆还没有在家里接受的辐射多呢。
但是这个人并没有说到底辐射对健康有没有害，只说了辐射比家里的小，不要大家担心。。。

所以A能解决这个疑问
