　　gre argument 108题目：

　　The following appeared in a Brenton newspaper.

　　"The Brenton power plant draws water from Scott&aposs River for its cooling system and releases the warmed water back into the river. The town council recommends that the plant install a more ficient cooling system that uses less water, claiming it will be more environmentally sound(5). However, in Uptown, where the new system is used, a study found that the complex network of pipes in the new system tends to accumulate algae(1). The build up of algae can be avoided by scrubbing the pipes, which is costly, or by adding an herbicide to the water in the pipes to prevent algae accumulation(2,3). But water containing the herbicide cannot be released back into the river(4) and it is known that low water levels(6) can harm river ecosystems accustomed to higher levels. Therore, Brenton power plant should continue to use the old cooling system exclusively(7)."

　　提纲：

　　(1)The problem in Uptown may not necessarily also occur in Brenton.

　　(2)The author does not provide any evidence to illustrate the necessity of eliminating algae.

　　(3)The author fails to inform us if there are any other possible methods to avoid, or to eliminate the build up of algae.

　　(4)Other possible methods might be available to eliminate the negative fect of herbicide contained in warmed water.

　　(5)The author fails to thoroughly evaluate the positive and negative fects of using the new system.

　　(6)The author does not inform us how much water does the power plant actually use, thus using the new system may not necessarily lead to low water level.

　　(7)The author ignores other possible methods besides using the two systems mentioned in the argument.

　　注：题目中括号里的数字表明这句话体现的是提纲中第几号缺陷。
