Productivity Of Service Workers

komal wrote: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.

the productivity is measeured by "letters delivered/ a postal worker"
the objection is --- although more letters are delivered per worker , more are lost or delayed

obviousely, it is arguing against how efficient the workers are doing their job, or quality of the services .

A. no other kind of service workers is implied in the question stem.
B. whether the work " delivery of letter" is primary or not is not the focuse.
C. it is discussing another thing about who should be measured; it is beyond the scope
E. it seems more like an assumption

i don't think my reasons are effective enough. i use my intuition and i just don't think ABCE are within the scop

can anyone help me !
