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?
65. 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.
问题: 1.此类“based on doubts”问题代表归纳题还是削弱题? 2.OG对正确答案的解释:The critique of the proposed purely quantitative measure of productivity raises the issue of quality of service, which implies that quality of service is a potentially relevant consideration. Thus, choice D is the best answer.不能理解既然quality of service是跟这个consideration有potential关系,为什么答案D中quality of service可以被ignore还是正确的?
