[作文互改] Argument 129 求拍求拍~狠狠拍吧~~~

129.The following appeared in a letter from the owner of the Sunnyside Towers apartment complex to its manager.
"One month ago, all the showerheads in the first three buildings of the Sunnyside Towers complex were modified to restrict maximum water flow to one-third of what it used to be. Although actual readings of water usage before and after the adjustment are not yet available, the change will obviously result in a considerable savings for Sunnyside Corporation, since the corporation must pay for water each month. Except for a few complaints about low water pressure, no problems with showers have been reported since the adjustment. Clearly, modifying showerheads to restrict water flow throughout all twelve buildings in the Sunnyside Towers complex will increase our profits further."
Write a response in which you discuss what specific evidence is needed to evaluate the argument and explain how the evidence would weaken or strengthen the argument.

On a perspective of a company, profit plays the essential role in its enterprises, and some managers would always consider about how to enhance their profits.  However, when a company is serving to public, it has to preserve a balance between the benefits of people and the income of the company.  The author of the letter makes a kind of evidence that seems as a shelter of the flaws in the author’s conclusion.  It would be listed in the following paragraphs.  

To cite the one-third of the water flow, the owner of the Sunnyside Towers apartment (S) refers to the evidence of restriction, which could be helpful for saving the spending of water of the corporation on each month.  The author ignores many different possibility.  First, the decrease of water flow might make the users to use water longer each time than before, and the sum of the water utilization would be without any change.  Secondly, the declined water flow might give the users a reason to choose another company for water accommodating. Losing the users, the profits might be influenced.  Without any justifiable evidence, it would be difficult for the author to predict the future profit whether it is going to be boosted or not.
 
As an evidence, the author indicates that because of a few complaints, the change makes no problems with the showers.  The report should be disputed that, maybe, there are many problems of the adjustment but all the users and the one who modified the machine of controlling water flow do not discover, or even more likely, the problems are still hided in a shadow which might be occurred in future. Besides, even there is not so much trouble of the modification, but the complaints of the users are intense outside the report. Some one might complain a lot without expressing to the researcher.  It is unjustifiable that the owner has only concentrated on the report literally. More analysis must be needed for the manager to make the determination.

According to the evidence which the owner indicates above, he concludes that the adjustment could be expended to all twelve buildings in S.  It means that the author gives an assumption of the fact that all users in twelve buildings would be the same as the people in the first three buildings after a month.  The threshold problem of the evidence is that the survey is only participated by a part of the user before one month.  This part of people might be change their mind after the month.  Differences must be occurred around all the people in the twelve buildings, which makes the reflection of the change would be far away from equivalence.  It would gives rise to more complaints of different aspects, and the problems would be revealed.  The writer should give more details about the other users of the buildings, and focus more on their benefits not only the profits of the company.
 
In short, more analysis would be needed for the manager to make the determination  of whether the change should be expended.  The owner should give more details about the other users of the buildings, and focus more on their benefits not only the profits of the company.  Losing the users, the profits might be influenced a lot.
