请帮我翻译下面两段话，谢谢了！！！

（1）Investments in service, like those in production and distribution,
(5) must be balanced against other types of investments on the
basis of direct, tangible benefits such as cost reduction and
increased revenues.

（2）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 perfor-
mance clearly supported the conclusion that supervisors  gave considerable weight to criteria such as
attendance .accuracy, and indications of customer
satisfaction.
