题目：
The following appeared in a letter from the owner of the Sunnyside Towers apartment building to its manager.
"One month ago, all the showerheads on the first five floors of Sunnyside Towers were modified to restrict the water flow to approximately one-third of its original flow. 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, restricting water flow throughout all the twenty floors of Sunnyside Towers will increase our profits further."
Write a response in which you discuss what questions would need to be answered in order to decide whether the recommendation is likely to have the predicted result. Be sure to explain how the answers to these questions would help to evaluate the recommendation.
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推荐是否能得到预期结果，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的。
