A threshold problem with the argument involves the voluntary nature of the evaluation
procedure. The dean provides no evidence about the number or percentage of Omega
146
students who participate in the procedure. Lacking such evidence it is entirely possible that
those numbers are insignificant, in which case terminating the procedure is unlikely to have
any effect on the grade average of Omega students or their success in getting jobs after
graduation.
The argument also assumes unfairly that the grade-average increase is the result of the
evaluation procedure--rather than some other phenomenon. The dean ignores a host of other
possible explanations for the increase--such as a trend at Omega toward higher admission
standards, or higher quality instruction or facilities. Without ruling out all other possible
explanations for the grade-average increase, the dean cannot convince me that by terminating
the evaluation procedure Omega would curb its perceived grade inflation let alone help its
graduates get jobs.
Even if the evaluation procedure has resulted in grade inflation at Omega, the dean's claim
that grade inflation explains why Omega graduates are less successful than Alpha graduates
in getting jobs is unjustified. The dean overlooks a myriad of other possible reasons for
Omega's comparatively poor job-placement record. Perhaps Omega's career services are
inadequate; or perhaps Omega's curriculum does not prepare students for the job market as
effectively as Alpha's. In short, without accounting for other factors that might contribute to
Omega graduates' comparative lack of success in getting jobs, the dean cannot justify the
claim that if Omega curbs its grade inflation employers will be more likely to hire Omega
graduates.
Finally, even if the dean can substantiate all of the foregoing assumptions, the dean's
assertion that Omega must terminate its evaluation procedure to enable its graduates to find
better jobs is still unwarranted, in two respects. First, the dean ignores other possible ways by
which Omega can increase its job-placement record--for example, by improving its public
relations or career-counseling services. Second, the dean unfairly equates "more" jobs with
"better" jobs. In other words, even if more Omega graduates are able to find jobs as a result of
the dean's recommended course of action, the kinds of jobs Omega graduates find would not
necessarily be better ones. 感谢您阅读《GRE作文范文大全（93） 》一文，查字典出国留学网()编辑部希望本文能帮助到您。本文主要讲解GRE作文相关内容，希望能帮助童鞋们提高写作能力。查字典出国留学网编辑部敬上。
In sum, the dean's argument is unpersuasive as it stands. To strengthen it the dean must
provide better evidence that the increase in grade average is attributable to Omega's
professor-evaluation procedure, and that the end result is a perception on the part of
employers that Omega graduates are less qualified for jobs than Alpha graduates. To better
assess the argument I would need to analyze 15-year trends in (l) the percentage of Omega
students participating in the evaluation procedure, (2) Omega's admission standards and
quality of education, and (3) Omega's emphasis on job training and career preparation. I would
also need to know what other means are available to Omega for enabling its graduates to find
better jobs.
Argument 9
The following appeared in a letter to the editor of a Batavia newspaper.
"The department of agriculture in Batavia reports that the number of dairy farms throughout the
country is now 25 percent greater than it was 10 years ago. During this same time period,
however, the price of milk at the local Excello Food Market has increased from $1.50 to over
147
$3.00 per gallon. To prevent farmers from continuing to receive excessive profits on an
apparently increased supply of milk, the Batavia government should begin to regulate retail
milk prices. Such regulation is necessary to ensure both lower prices and an adequate supply
of milk for consumers."
This editorial recommends that Batavia's government regulate milk prices because profits from
milk sales are excessive given the apparently adequate supply. The editorial also claims that
price regulation would help ensure an adequate supply of milk. To support these assertions the
author cites the fact that over the past ten years the number of dairy farms in Batavia has
increased by 25% while at ExceUo Food Market milk prices have increased by 100%.
However, the argument relies on a series of unsubstantiated assumptions, which render it
unconvincing as it stands.
First of all, the author assumes that ExceUo's milk prices reflect those throughout Batavia.
However, the author provides no evidence that this is the case. To the extent that Excello's
milk prices currently exceed nationwide averages the author's argument for government
regulation of milk prices would be undermined. 感谢您阅读《GRE作文范文大全（93） 》一文，查字典出国留学网()编辑部希望本文能帮助到您。本文主要讲解GRE作文相关内容，希望能帮助童鞋们提高写作能力。查字典出国留学网编辑部敬上。
In the second place, even if ExceUo's milk prices reflect those in Batavia generally, in
claiming that milk prices are particularly "excessive" the author assumes that milk-sale profits
exceed profits from the sale of other goods in Batavia to a significant degree. But the author
provides no evidence to substantiate this assumption. Perhaps other prices have risen
commensurably, or perhaps even more on a percentage basis, during the same t/me period.
Moreover, perhaps profit margins from the sale of other goods are even greater than profits
from milk sales. In either event the author could not justifiably rely on the mere fact that milk
prices have increased by 100% to support the claim that milk sale profits are excessive.
In the third place, the author assumes that an increase in milk prices results in increased
profits. However, this is not necessarily the case. It is entirely possible that the costs
associated with producing and delivering milk have increased as well over the last ten years.
Thus the strength of the author's claim of excessive milk-sale profits depends on a cost-benefit
analysis that the author does not provide.
In the fourth place, based on the fact that the number of dairy farms has increased the
author infers that the supply of milk has also increased. However, this is not necessarily the
case. It is possible that dairy farm production has shifted away from milk to other dairy
products, and that the supply of milk has actually declined over this time period. To the extent
that this is the case, then the author's supply-and-demand argument that milk prices are
excessive is unconvincing.
Finally, in asserting that price regulation would help ensure an adequate supply of milk the
author overlooks the possibility that milk producers would respond to the regulation by
producing less milk, depending on the extent to which demand increases as a result of lower
milk prices. If regulation has the effect of lowering profits, then common sense tells me that
milk producers might be less inclined to produce milk. Without ruling out this possible scenario,
the author cannot convince me that the recommendation would help ensure an adequate
supply of milk.
In conclusion, the recommendation for regulation of milk prices is not well supported. To
convince me that the proposed regulation is needed to ensure a reasonably priced milk supply,
148
the author must provide clear statistical evidence that Excello's milk prices reflect nationwide
milk prices and that profits from milk sales are in fact excessive. To better evaluate the
recommendation, I would need more information about how the proposed regulation would
effect both the supply of milk and the demand for milk in Batavia.
Argument 10
The following appeared in a memo from the mayor of the town of West Egg.
"Two years ago, our consultants predicted that West Egg's landfill, which is used for garbage
disposal, would be completely filled within five years. During the past two years, however, town
residents have been recycling twice as much aluminum and paper as they did in previous
years. Next month the amount of material recycled should further increase, since charges for
garbage pickup will double. Furthermore, over ninety percent of the respondents to a recent
survey said that they would do more recycling in the future. Because of our residents' strong
commitment to recycling, the available space in our landfill should last for considerably longer
than predicted." 感谢您阅读《GRE作文范文大全（93） 》一文，查字典出国留学网()编辑部希望本文能帮助到您。
