求助 OG 11th CR 第112题 （P617)

OHHHHH

不好意思~之前忘了写答案E了~~

112、In tests for pironoma, a serious 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 laboratlory tests used to detect pironoma.

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

我。。我还是不太懂~~为什么为了选出缺点A比较不严重，就得要所有东西的B缺点一样严重呢？

是不是这样理解，因为所有东西的B缺点一样严重，所以就无所谓的比较不严重的这种区分了？进而就转向选出缺点A比较不严重的？

OHHHHH

噢~~~~~~~~~~~~~~哈哈。。你这个例子真实在啊！谢谢啊~
