Secondly, the 300 people in the study are not necessarily representative of the state’s
general population – in terms of their susceptibility to health problems. For example, perhaps
nearly all of these people are adults, while most of the health problems associated with trash
sites occur among children. Or perhaps preventative health-care programs in these particular
communities are unusually effective in preventing ealth problems. In short, lacking evidence
that these 300 people are typical in terms of their vulnerability to health problems the Council
cannot convince me that no statewide trash-site regulations are needed.
Thirdly, the Council’s conclusions that the five sites studies pose no serious health hazards
to nearby residents seems premature. Common sense informs me that a serious health
problem might become apparent only after a long period of exposure to the environmental
cause of the problem. The Council fails to take into account the length of time these residents
have been exposed to the conditions created by the trash sites; and in any event, one “recent”
study amounts to scant evidence that the sites pose no significant long-term public-health
hazards.
In sum, the Council’s argument is unconvincing as it stands. To strengthen it the Council
must provide better evidence that the environmental conditions at the five sites studies
represent conditions at trash sites througouth the state, and that the 300 people studies are
representative of state residents generally in terms of vulnerability to health problems. To
better assess the argument I would need more information comparing the health of the 300
people studied before and after continual exposure to the environmental conditions associated
with the trash sites. I would also need to know the length of the study to determine whether it
adequately accounted for latent health problems. 感谢您阅读《GRE作文范文大全（114） 》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 47
The nation of Claria covers a vast physical area. But despite wide geographic differences,
many citizens are experiencing rising costs of electricity. A recent study of household electric
costs in Claria found that families who cooled their houses with fans alone spent more on
electricity than did families using air conditioners alone for cooling. However, those households
that reported using both fans and air conditioners spent less on electricity than those
households that used either fans or air conditioners alone. Thus, the citizens of Claria should
follow the study's recommendation and use both air conditioners and fans in order to save
money on electricity.
This argument recommends that all citizens of Claria should mn fans as well as air
conditioners, for the purpose of saving money on electricity. To support this recommendation,
the argument's proponent points out that Claria citizens who run only fans incur higher electric
costs than those who mn only air conditioners, and that those who run both incur the lowest
electric costs among the three groups. However, the argument depends on certain dubious
assumptions about climate, electric costs, and the cited statistics. As a result, the
recommendation is iU-conceived.
First, the argument relies on the assumption that climatic conditions are similar throughout
all regions of Claria. Yet this is probably not the case, especially since the passage explicitly
193
characterizes Claria as vast and widely diverse geographically. It is entirely possible that only
fans are used in certain regions because the climate in these regions is comparatively cold
year-round, and that electric heating costs are so high that they result in the highest overall
electric costs in the country. If this is the case, implementing the proponent's suggestion would
result in higher electric costs for citizens in these regions. Or perhaps people who run both
fans and air conditioners live in regions where there is less need for artificial cooling. This
would explain why total electric costs in these regions are comparatively low. If this is the case,
then implementing the proponent's suggestion might still result in higher electric costs for
citizens in other regions. 感谢您阅读《GRE作文范文大全（114） 》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。
Secondly, the recommendation depends on the assumption that the cost of electricity is the
same for all three groups. However, it is possible that people who use both fans and air
conditioners incur the lowest total electric costs among the three groups simply because these
people pay the least per unit of electricity. The fact that Claria is geographically diverse lends
support to this notion; people who use both fans and air conditioners are likely to live in the
same climatic region, and people in the same region are more likely to be subject to the same
electricity usage rates.
Thirdly, the argument provides insufficient information about the study on which it relies. If the
results were based on only one warm season then the argument would be less persuasive
than if the results were based on more than one warm season; in other words, the larger the
statistical sample the more reliable the results.
In condusion, the recommendation for using both cooling methods is dubious at best. To
bolster it, the argument's proponent must show that climatic conditions are similar in all regions.
The proponent must also show that rates charged for electricity are similar in all regions.
Finally, in order to better evaluate the extent to which the cited study supports the
recommendation we would need more statistical information about the study's time span.
Argument 48
As people grow older, an enzyme known as PEP increasingly breaks down the neuropeptide
chemicals involved in learning and memory. But now, researchers have found compounds that
prevent PEP from breaking neuropeptides apart. In tests, these compounds almost completely
restored lost memory in rats. The use of these compounds should be extended to students
who have poor memory and difficulty in concentrating-and therefore serious problems in
school performance. Science finally has a solution for problems neither parents nor teachers
could solve.
This argument concludes that certain compounds should be administered to students with
poor memory and concentration to improve their performance in school. The argument cites
an experiment involving rats in which the same compounds prevented the enzyme PEP from
breaking down chemicals involved in learning and memory. The argument suffers from several
flaws, which render it unconvincing. 感谢您阅读《GRE作文范文大全（114） 》一文，查字典出国留学网()编辑部希望本文能帮助到您。
