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 1/3 of its original force. Although actual readings of water usage before and after the adjustment are not yet available(3), 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(4) about low water pressure, no problems with showers(2) have been reported since the adjustment(1). Clearly, restricting water flow throughout all the 20 floors(6) of Sunnyside Towers(5) will increase our profits further(7)."
提纲：
1. The modification was taken place only one month ago, thus many negative effects might not have emerged yet.
2. The owner does not provide detailed information about the usage of the first five floors of Sunnyside Towers, perhaps water flow is not a problem here at all.
3. Without any actual readings of water usage before and after the adjustment we cannot evaluate if the modification could actually save water.
4. The fact that a few people complained about water pressure does not necessarily indicate that all other clients are satisfied with the modification.
5. The owner ignores many negative effects of restricting the water flow.
6. The owner hastily assumes that the restricting on water flow could be successfully carried out to all other floors of Sunnyside Tower.
7.Adopting the owner’s suggestion alone may not suffice to ensure increased profits.
