20. In tests 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 the other laboratory tests used to detect pironoma.

(C) In treating pironoma patients, it is essential to begin treatment as early as 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 negative results.

此题答案为e，哪位NN能解释一下，还有，BD错在哪里？谢谢

这题逻辑推理过程是这样的：

为了准确测试P病，医生应该用最少假阳性结果的试验室测试方法，即这里说的是测试方法的准确性。

而B，D分别谈论的是测试方法的副作用和非决定性结果的比例，与题干讨论的话题无关。
