simply cannot convince me that CCC must abandon its plans in order that such damage be
prevented.
Secondly, even assuming CCC's planned mining activities in West Fredonia will cause
pollution and will endanger several animal species, it is nevertheless impossible to assess the
author's broader contention that CCC's activities will result in "environmental disaster,'' at least
without an agreed-upon definition of that term. If by "environmental disaster" the author simply
means some pollution and the extinction of several animal species, then the claim would have
merit; otherwise, it would not. Absent either a clear definition of the term or dear evidence that
CCC's activities would carry grave environmental consequences by any reasonable definition,
the author's contention that CCC's activities will result in environmental disaster is simply
unjustified.
Thirdly, the author's position that environmental disaster is "inevitable" absent the prescribed
boycott precludes the possibility that other measures can be taken to prevent CCC from
carrying out its plans, or to offset any harm that CCC causes should it carry out its plans. Yet
the author fails to provide assurances that no other means of preventing the predicted disaster
are available. Lacking such evidence the author cannot reasonably conclude that the
proposed boycott is needed to prevent that disaster.
Finally, even if the prescribed boycott is needed to prevent pollution and environmental
disaster in West Fredonia, the author assumes too hastily that the boycott will suffice for these
purposes. Perhaps additional measures would be required as well. For instance, perhaps
consumers would also need to boycott other companies that pollute West Fredonia's
environment. In short, without any evidence that the recommended course of action will be
enough to prevent the predicted problems, the author's conclusion remains dubious at best.
In sum, as it stands the argument is wholly unpersuasive. To bolster it the author must show
that CCC's planned mining activities on its newly acquired land will pollute and will threaten
endangered animal species. The author must also define "environmental disaster'' and show
that the inevitable results of CCC's activities, absent the proposed boycott, would meet that
definition. To better assess the argument it would be useful to know what other means are
available for preventing CCC from mining in West Fredonia or, in the alternative, for mitigating
the environmental impact of those mining activities. A/so useful would be any information
about the likelihood that the boycott would be effective in accomplishing its intended
objectives. 感谢您阅读《GRE作文范文大全（105） 》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。
Argument 30
The article entitled 'Eating Iron' in last month's issue of Eating for Health reported that a recent
study found a correlation between high levels of iron in the diet and an increased risk of heart
disease. Further, it is well established that there is a link between large amounts of red meat in
the diet and heart disease, and red meat is high in iron. On the basis of the study and the
well-established link between red meat and heart disease, we can conclude that the
correlation between high iron levels and heart disease, then, is most probably a function of the
correlation between red meat and heart disease. The following appeared as a letter to the
editor of a national newspaper.
In this argument the author dtes a study correlating the amount of iron in a person's diet with
173
the person's risk of heart disease. The author also cites a well-established correlation between
diets that indude large amounts of red meat, which is high in iron, and the incidence of heart
disease. The author concludes that the correlation observed in the study is a function of the
correlation between read meat and heart disease. This argument suffers from a series of poor
assumptions, which render it wholly unpersuasive as it stands.
To begin with, the author provides no evidence that the study's results are statistically
reliable. In order to establish a strong correlation between dietary iron and heart disease, the
study's sample must be suffident in size and representative of the overall population of
heart-disease victims. Lacking evidence of a suffidenfly representative sample, the author
cannot justifiably rely on the study to draw any conclusion whatsoever.
Even assuming that the study is statistically reliable, a direct correlation between a high-iron
diet and heart disease does not necessarily prove that the former causes the latter. While a
high correlation is strong evidence of a causal relationship, in itself it is not suffident. The
author must also account for all other possible factors leading to heart disease, such as
genetic propensity, amount of exercise, and so forth. Lacking evidence that the heart-disease
sufferers whom the study observed were similar in all such respects, the author cannot
justifiably conclude that a high-iron diet is the primary cause, or even a contributing cause, of
heart disease.
Similarly, a correlation between a diet, which includes large amounts of red meat and heart
disease, does not necessarily infer a causal relationship. Lacking evidence to the contrary, it is
possible that red-meat eaters are comparatively likely to incur heart disease due to factors that
have nothing to do with the amount of red meat in their diet. Perhaps red-meat eaters are the
same people who generally overeat, and it is obesity rather the consumption of red meat
specifically that causes heart attacks. The author must consider and eliminate this and other
possible reasons why red-meat eaters are more likely than other people to suffer from heart
disease. Otherwise, I cannot accept the author's implidt daim that eating red meat is any more
likely to cause heart disease than eating other foods.
Even assuming that a high-iron diet, including a diet high in red meat, promotes heart
disease, the author cannot reasonably conclude that this causal relationship fully explains the
study's results. The author overlooks the possibility that other foods are also high in iron, and
that the study's participants ate these other foods as well as, or instead of, red meat. Without
accounting for this possibility the author cannot convincingly conclude from the study that red
meat is the chief cause of heart disease. 感谢您阅读《GRE作文范文大全（105） 》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 conclusion, the argument unfairly assumes that correlation is tantamount to causation. To
strengthen the argument, the author must provide dear evidence that a high-iron diet
contributes to heart disease. The author must also provide dear evidence that people who eat
red meat are more likely to incur heart disease because of the amount of red meat in their diet,
rather than some other factor. To better evaluate the reliability of the study upon which the
author's conclusion depends, I would need more information about the size and makeup of the
study's sample. I would also need to know whether other foods are also high in iron and, if so,
which high-iron foods the study's participants ate on a regular basis.
Argument 31
"Your recent article on corporate downsizing* in the United States is misleading. The article
174
gives the mistaken impression that many competent workers who lost jobs as a result of
downsizing face serious economic hardship, often for years, before finding other suitable
employment. But this impression is contradicted by a recent report on the United States
economy, which found that since 1992 far more jobs have been created than have been
eliminated. The report also demonstrates that many of those who lost their jobs have found
new employment. Two-thirds of the newly created jobs have been in industries that tend to pay
above-average wages, and the vast majority of these jobs are full-time."
*Downsizing is the process in which corporations deliberately reduce the number of their
employees.
This editorial disagrees with a certain article's claim that as a result of widespread corporate
downsizing many able workers have faced serious long-term economic hardship--due to their
inability to find other suitable employment. To justify its disagreement with this daim the
editorial cites the following three findings of a recent report: (1) There has been a net increase
in the number of new jobs created since 1992, (2) many workers who lost their jobs have found
other work, and (3) most newly created jobs are full-time positions in industries which tend to
pay above-average wages. Careful scrutiny of these findings, however, reveals that they
accomplish little toward refuting the article's claim.
Regarding the fu:st finding, the editorial overlooks the possibility that most of the newly
created jobs since 1992 are not suitable for job-seekers downsized by corporations. Perhaps
the vast majority of these jobs involve food serving, clerical assistance, deanmg and
maintenance, and other tasks requiring a low level of skill and experience. At the same 6me,
perhaps most downsized job-seekers are highly educated middle-managers looking for the
same type of work elsewhere. In short, lacking evidence that the newly created jobs match the
skills, experience, and interests of the downsized corporate employees, the editorial's author
cannot convincingly refute the article's claim. 感谢您阅读《GRE作文范文大全（105） 》一文，查字典出国留学网()编辑部希望本文能帮助到您。
