110. Correctly measuring the productivity of service workers is complex. Consider, for example, postal workers: they are often said to be more productive if more letters are delivered per postal worker. But is this really true? What if more letters are lost or delayed per worker at the same time that more are delivered?

The objection implied above to the productivity measure described is based on doubts about the truth of which of the following statements?

(A) Postal workers are representative of service workers in general.

(B) The delivery of letters is the primary activity of the postal service.

(C) Productivity should be ascribed to categories of workers, not to individuals.

(D) The quality of services rendered can appropriately be ignored in computing productivity.

(E) The number of letters delivered is relevant to measuring the productivity of postal workers.

為何(E)不行呢?


(E) The number of letters delivered is relevant to measuring the productivity of postal workers.

為何(E)不行呢?

E，是一个事实，是作者举的一个example，作者后面用But is this really true?表示怀疑，

举出了一个特例if more letters are lost or delayed per worker at the same time that more are delivered?

因此不能仅仅凭The number of letters delivered 来衡量productivity of postal workers。

题目问: the productivity measure described is based on doubts about the truth of which of the following statements...选项(E) 不就是作者质疑的 "送信数量=productivity of postal workers"而且我排除(D)是因为觉得题目没提及:The quality of services 所以才会觉得D是无关选项

What if more letters are lost or delayed per worker at the same time that more are delivered？
题设最后一句话明确承认了二者都是productivity的评价相关项
怎么会是对relevant怀疑呢
作者是承认number是指标之一的啊

题目是问作者的反驳是建立在对什么的置疑上面.
D: 是对 "QOS 可以在计算生产力的时候忽略" 进行置疑, 和原文吻合, 对于邮递员的QOS 就是丢失的程度.
而E 是对 "信的数量是和计算生产力有关的" 进行置疑, 原文并没有置疑这个, 而是在默认了这个的基础上反驳说这个不是唯一计算生产力的因素.
