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.

这道题目可以这样看：
只有两种错误：false negative 和false positive
写成公式：总的错误 =“false negative ”+“false positive”
如果false negative都一样，那么错误率只和false positive有关，那么false positive越低整个错误率就越低，准确率就越高了。

有pironoma，测试结果是positive，没有，结果是negative；原文中a false positive result 和a false negative result说明错误的测试结果导致错误的结论。因此要用新的方法能将   错误的positive 结果比例最小化 也就是laboratory test 。E就是排除他因，加强了原文的结论。

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！

归纳类的题绝对不能有原ARGUMENT里没有的东西，归纳题用排除法最简单。
