2012gre作文大讲堂:GRE作文范文大全(94)
Finally, the mayor provides no evidence that the survey's respondents are representative of
the overall group of people whose trash goes to the city's landfill. Lacking such evidence, it is
entirely possible that people inclined to recycle were more willing to respond to the survey than
other people were. In short, without better evidence that the survey is statistically reliable the
mayor cannot rely on it to draw any firm conclusions about the overall recycling commitment of
West Egg residents--let alone about how quickly the landfill will reach capacity.
In sum, the mayor's projection is simply not credible, at least based on the memo. Rather
than relying solely on questionable recycling statistics, the mayor should provide direct
evidence that the amount of trash going to the landfill is declining and that this trend will not
reverse itself anytime soon. To better assess the accuracy of the mayor's projection it would be
useful to know who besides West Egg residents contributes trash to the land fLU, and whether
the amount of trash those people contribute is declining or is likely to decline in the near future.
Argument 11
The following appeared in a memo from a vice president of Alta Manufacturing.
"During the past year, Alta Manufacturing had thirty percent more on-the-job accidents than
nearby Panoply Industries, where the work shifts are one hour shorter than ours. Experts
believe that a significant contributing factor in many on-the-job accidents is fatigue and sleep
deprivation among workers. Therefore, to reduce the number of on-the-job accidents at Alta
and thereby increase productivity, we should shorten each of our three work shifts by one hour
so that our employees will get adequate amounts of sleep."
This editorial recommends that Alta Manufacturing reduce its work shifts by one hour each in
order to reduce its on-the-job accident rate and thereby increase Alta's productivity. To support
this recommendation the author points out that last year the number of accidents at Alta was
30% greater than at Panoply Industries, where work shifts were one hour shorter. The author
also cites certain experts who believe that many on-the-job accidents are caused by fatigue
and sleep deprivation. I find this the argument unconvincing for several reasons.
First and foremost, the author provides absolutely no evidence that overall worker
productivity is attributable in part to the number of on-the-job accidents. Although common
sense informs me that such a relationship exists, the author must provide some evidence of
this cause-and-effect relationship before I can accept the author's final conclusion that the
proposed course of action would in fact increase Alta's productivity. 感谢您阅读《GRE作文范文大全(94) 》一文,出国留学网(liuxue86.com)编辑部希望本文能帮助到您。
