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.

简单的说就是这样 有这么一堆东西 他们都有两个缺点 A和B 结论：为了选出比较好的 应该选A缺点比较不严重的

正确答案就是 所以有的东西他们的B缺点都一样严重（排除他因削弱的可能，所以加强）

好理解吧？

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？

对 完全正确 就是这个道理

举个简单的例子 MM选GG 希望GG又帅又有钱

然后有这么一排GG都巨帅 随便挑一个都堪比王丽红之流 于是MM只管问谁有钱就好了
