题目：
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. I predict that modifying showerheads to restrict water flow throughout all twelve buildings in the Sunnyside Towers complex will increase our profits even more dramatically."
Write a response in which you discuss what questions would need to be answered in order to decide whether the prediction and the argument on which it is based are reasonable. Be sure to explain how the answers to these questions would help to evaluate the prediction.
中文翻译：
一个月前，Sunnyside塔楼最低的五层的所有淋浴喷头被调节成水压只有以前的大约三分之一。尽管在调节之后用水量的确切读数还没有出来，但这种变革显然将为Sunnyside公司节省大量的花费，因为公司必须每月为所用的水付费。除了关于低水压的几起投诉，在调节之后没有发生关于淋浴喷头的问题的报告。我预计在Sunnyside塔楼所有的12层都限制水压将会增加我们未来的利润。
写一篇回应，在其中讨论还有哪些问题需要被回答才能决定文中的建议以及得出这一建议预测的论证过程是合理的，并务请解释对这些问题的回答是如何帮助更好的评估文中的建议预测的。
