       In an attempt to improve the overall performance of clerical workers, many companies have introduced computerized performance monitoring and control systems (CPMCS) that record and report a worker’s computer-driven activities. However, at least one study has shown that such monitoring may not be having the desired effect. In the study, researchers asked monitored clerical workers and their supervisors how assessments of productivity affected supervisors’ ratings of workers’ performance. In contrast to unmonitored workers doing the same work, who without exception identified the most important element in their jobs as customer service, the monitored workers and their supervisors all responded that productivity was the critical factor in assigning ratings. This finding suggested that there should have been a strong correlation between a monitored worker’s productivity and the overall rating the worker received. However, measures of the relationship between overall rating and individual elements of performance clearly supported the conclusion that supervisors gave considerable weight to criteria such as attendance, accuracy, and indications of customer satisfaction.

       It is possible that productivity may be a “hygiene factor,” that is, if it is too low, it will hurt the overall rating. But the evidence suggests that beyond the point at which productivity becomes “good enough,” higher productivity per se is unlikely to improve a rating.

   Which of the following, if true, would most clearly have supported the conclusion referred to in lines 19-21（黑体）?

(A) Ratings of productivity correlated highly with ratings of both accuracy and attendance.

(B) Electronic monitoring greatly increased productivity.

(C) Most supervisors based overall ratings of performance on measures of productivity alone.

(D) Overall ratings of performance correlated more highly with measures of productivity than the researchers expected.

(E) Overall ratings of performance correlated more highly with measures of accuracy than with measures of productivity.

答案是e，怎么分析出来的？请教大家了~~

原文那段说的意思就是

用电脑给员工评分有一个问题就是不能衡量生产力，但大家又都认为生产力是员工评分的重要标准之一。

黑体字说：打分系统和员工表现因素（包括出勤等等）说明一个问题，这个问题就是监工把生产力之外的因素看得太重。

E说rating和accuracy联系太紧密，超过了和生产力的联系，那么显然，这句话意思就是说rating不能反映生产力了。同黑体字一个意思

谢谢rio,原来文章都没有彻底搞明白......

sorry, 不敢苟同

原文的意思是CPMCS系统使使用这一系统的员工和主管形成了一种perception就是生产效率直接影响主管对手下员工的评分，而事实证明评分的结果与attendance, accuracy, and indications of customer satisfaction密切相关，也就是line 19-21的意思，隐含的意思就是其三者都比productivity对评分的影响要大，由此得到E

感觉意思是差不多的吧...晕了
