109. 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.

Argument Evaluation

Situation    In considering how best to measure productivity, the assumption is made that the more letter postal workers deliver, the more productive they are. This assumption is then challenged: What if the number of delayed and lost letters increases proportionately with the number of letters delivered?

Reasoning
          Which statement would NOT be accepted by those objecting to the measure? The point of the objection is that the number of letters delivered is, by itself, an inadequate measure of postal workers’ productivity. The challenge introduces the issue of the quality of the work being performed by suggesting that the number of misdirected letters should also be taken into account. The challenge is based on rejecting the idea that quality can be ignored when measuring productivity.

A  The argument uses postal workers as an example; the challenge does not question the fairness of the example.

B  Letter delivery is assumed to be the primary activity of postal workers because their productivity is measured on that basis; the challenge does not reject this point.

C  The argument does discuss a category of workers, postal workers, rather than individual; the challenge does not reject this point.

D  Correct. This statement properly identifies the point that is the basis of the challenge to the measure; the objection does NOT accept the position that quality can be ignored in evaluating productivity.

E  There is no doubt that counting letters delivered is part of measuring productivity; the challenge is to its being the only measure.

太棒了！
