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.


答案是D，虽然我感觉没有一个是有关的      很不解的就是怎么就和 quality 扯上关系了？ letter多少跟 quality 有毛关系？

总感觉中间我还有个Gap没有跨越？求大神指点

我觉得作者在这儿表达的是：觉得要准确计算服务业的效率是非常复杂的。然后作者通过列举邮递员的例子来引出自己的观点：is this ture? 即送信越多效率就真的越高吗？
这题属于Assumption的题型。
ABC都无关。D选项的意思“注重产量，无视服务质量”，作者不正是基于此提出的疑惑吗？所以D是该题的一个Premise.
然后我觉得E跟例子表达的是一个意思，属于重复premise吧...
