Thirdly, the speaker assumes that the bones of fish that archeologists have found discarded
on the island were discarded by humans, and not by some other large mammal. However, the
speaker provides no evidence to substantiate this assumption. Given other possible
explanations for these discarded fish bones, this evidence in itself lends little credible support
to the speaker's theory about the extinction of large species of mammals.
In conclusion, the argument is unconvincing as it stands. To strengthen it, the speaker must
rule out the possibility that humans exported the bones of these other species. To better
evaluate the argument, we would need more information about the diet of humans and of the
now-extinct mammals during that time period; particularly, we would need to know whether
those other mammals also fed on the fish whose discarded bones have been found on the
islands.
Argument 88
The following appeared in a newspaper feature story.
"At the small, nonprofit hospital in the town of Saluda, the average length of a patient's stay is
237
two days; at the large, for-profit hospital in the nearby city of Megaville, the average patient
stay is six days. Also, the cure rate among patients in the Saluda hospital is about twice that of
the Megaville hospital. The Saluda hospital has more employees per patient than the hospital
in Megaville, and there are few complaints about service at the local hospital. Such data
indicate that treatment in smaller, nonprofit hospitals is more economical and of better quality
than treatment in larger, for-profit hospitals."
This newspaper story concludes that the small, nonprofit hospital in Saluda provides more
efficient, better-quality care than the for-profit hospital in Megaville. To justify this conclusion
the author cites the following comparisons between the Saluda hospital and the Megaville
hospital: At the Saluda hospital the average length of a patient's stay is shorter, the cure rate
and employee-patient ratio are both higher, and the number of complaints from patients is
lower. However, careful consideration of these facts reveals that they fail to justify the author's
conclusion.
In the first place, the author unfairly assumes that a shorter hospital stay indicates a quicker
recovery and therefore better care. It is equally possible that the Saluda hospital simply cannot
afford to keep patients as long as it should to ensure proper care and recovery. Perhaps the
hospital sends patients home prematurely for the purpose of freeing up beds for other patients.
Since the author has failed to rule out other possible explanations for this shorter average stay,
I remain unconvinced based on this evidence that the Saluda hospital provides better care
than Megaville's hospital. 感谢您阅读《GRE作文范文大全（136） 》一文，查字典出国留学网()编辑部希望本文能帮助到您。GRE考试形式：中国大陆地区、香港、澳门、韩国目前执行分开考试的形式。由机考（分析性写作）和笔试（语文、数学）组成。
In the second place, the mere fact that the rate of cure at the Saluda hospital is higher than
at MegaviUe's hospital proves nothing about the quality of care at either hospital. It is entirely
possible that more Saluda patients suffer from curable problems than Megaville patients do.
Without considering this possibility the author cannot justifiably rely on curerates to draw any
conclusions about comparative quality of care.
In the third place, a higher employee-patient ratio at Saluda is weak evidence of either better
care or greater efficiency. Common sense informs me that it is the competence of each
employee, not the number of employees, that determines overall q, ality of care. Besides, it is
entirely possible that the comparatively large staff at Saluda is the result of organizational
inefficiency, and that a smaller staff of more effective, better managed people would provide
better care.
Finally, the mere fact that the Saluda hospital receives fewer patient complaints than
MegaviUe's hospital proves nothing about either efficiency or quality of care. Even though the
number of complaints is smaller, the percentage of patients complaining might be higher. Also,
MegaviUe's staff might openly encourage patient feedback while Saluda's does not. This
scenario accords with my observation that for-profit organizations are generally more
concerned with customer satisfaction than non-profit organizations are.
In sum, the facts that the story cites amount to weak evidence that the Saluda hospital
provides more efficient, better-quality care than Megaville's hospital. To strengthen the
argument, the author must provide dear evidence that at the Saluda hospital patients are
released earlier because they have received better care--rather than for some other reason. To
better assess the argument, I would need to compare the percentage of MegaviUe's hospital
patients who suffer from curable problems with the percentage of Saluda patients who suffer
238
from similar problems. Also, I would need more information from each hospital about complaint
procedures and the percentage of patients who lodge complaints.
Argument 89
The following appeared as a letter to the editor of a farming publication.
"With continuing publicity about the need for healthful diets, and with new research about the
harmful effects of eating too much sugar, nationwide demand for sugar will no doubt decline.
Therefore, farmers in our state should use the land on which they currently grow sugar cane to
grow peanuts, a food that is rich in protein and low in sugar. Farmers in the neighboring
country of Palin greatly increased their production of peanuts last year, and their total revenues
from that crop were quite high." 感谢您阅读《GRE作文范文大全（136） 》一文，查字典出国留学网()编辑部希望本文能帮助到您。GRE考试形式：中国大陆地区、香港、澳门、韩国目前执行分开考试的形式。由机考（分析性写作）和笔试（语文、数学）组成。
This letter concludes that to increase farm revenue this country's farmers should replace
their sugar crops with peanuts. To support this assertion, the letter's author claims that demand
for sugar is sure to decline due to a growing awareness of the health hazards of eating too
much sugar. The author also cites the fact that in the nearby country of Palm increased peanut
production has resulted in increased revenue for farmers. However, the author's argument
relies on several poor assumptions, and is therefore unpersuasive as it stands.
A threshold problem with the letter involves the new research that the author cites to support
his condusion. The author fails to indicate whether consumers are in fact aware of the new
research about the harmful effects of eating too much sugar, or whether consumers eat too
much sugar in the first place. If consumers are unaware of the research, or if they do not
currently eat too much sugar, then this research lends no support to the author's assertion that
sugar consumption is likely to decline as a result of the new research.
Secondly, the argument unjustifiably assumes that growing consumer awareness of sugar's
health hazards will cause consumers to not only decrease sugar consumption but also
increase peanut consumption. Common sense informs me otherwise, especially considering
the addictive quality of sugar. In fact, the author provides explicitly that peanuts are low in
sugar, suggesting that peanuts are a poor substitute for sugar.
Thirdly, the author's daim that farm revenues will increase should farmers replace sugar
crops with peanuts relies on certain dubious economic assumptions. One such assumption is
that the market price of peanuts will be sufficiently high to compensate for lost revenue from
current sugar sales. Another is that the supply of peanuts will suffice to provide farmers with
sufficient revenue. Absent evidence comparing the market price of sugar to that of peanuts, as
well as evidence about the capacity of this country's farms to grow peanut crops, it is
impossible to assess the author's assertion that replacing sugar crops with peanuts will
increase farm revenues.
Finally, the author's reliance on the fact that peanut-farming revenues in neighboring Pain
have increased is problematic in two respects. First, the analogy depends on the assumption
that dietary tastes of consumers in both countries are similar. However, it is entirely possible
that consumer demand for peanuts in Pain would be higher than that in this country in any
event. This would explain why, in Palin, demand has met increased production, and therefore
why Palin's peanut-farming revenues have increased. The analogy also depends on the
239
assumption that environmental conditions in both countries equally support peanut crops. If
they do not, then the author cannot justifiably rely on the profitability of Pain's peanut farms to
conclude that peanut farms in the author's country would be just as profitable. 感谢您阅读《GRE作文范文大全（136） 》一文，查字典出国留学网()编辑部希望本文能帮助到您。
