OG-87 是怎么理解的？为什么选E呢？

87. In test for pironoma, a serious disease, a false positive result indicates that people have pironoma when, in fact, they do not; a false negative result indicates that people do not have pironoma when, in fact, they do. To detect pironoma most accurately, physicians should use the laboratory test that has the lowest proportion of false positive results.

Which of the following, if true, gives the most support to the recommendation above?

(A) The accepted treatment for pironoma does not have damaging side effects.

(B) The laboratory test that has the lowest proportion of false positive results causes the same minor side effects as do other laboratory tests used to detect pironoma.

(C) In treating pironoma patients, it is essential to begin treatment as early as do possible, since even a week of delay can result in loss of life.

(D) The proportion of inconclusive test results is equal for all laboratory tests used to detect pironoma.

(E) All laboratory tests to detect pironoma have the same proportion of false negeative results.

哎哟，除了snowflower MM，咋就没有人理我呢，我自己想明白了，解释一下：这个支持当假设来做，（E）是排除他因，与OG100题一摸一样，一个结果本来有多个因素影响，要得到只有其中一个因素是在起作用的结果，就得排除其他方面的因素的影响。但让我不解的是：the lowest proportion of false positive results. 这个短语是怎么理解的？有没有XDJM可以帮忙一下，谢谢！

我的理解是，如果所有实验室的测试得出的错误的阴性结果是一样的，那说明这个已经没得变了，那么要提高准确率，只能采用错误的阳性结果最少的方法了。。。

还是晕，谁来更好的解释下

同意. 在对一个事物有影响的两个因素中，一个因素相等,那么起作用的就是另外一个因素.
