OG 20 694

City council member: Demand for electricity has been increasing by 1.5 percent a year, and there simply is no more space to build additional power plants to meet future demand increases. We must therefore begin to curtail usage, which is why I propose passing ordinances requiring energy-conservation measures in all city departments.
The city council member’s proposal assumes which of the following?
A. Existing power plants do not have the capacity to handle all of the projected increase in demand for electricity.                           

B. No city departments have implemented energy-conservation measures voluntarily.                           

C. Passing ordinances designed to curtail electricity usage will not have negative economic consequences for the city.                             

D. Residential consumers are not responsible for the recent increases in demand for electricity.                           

E. City departments that successfully conserve energy will set a good example for residential and industrial consumers of electricity.

这道题，我的思路是D增长，空间不够不能建新的发电厂——只能通过减少usage，具体是pass ordinance in all city departments. 所以我可以理解A是最好选项。
但是关于D和E我有些不解。
D：如果这个D的增长是由于consumers引起的，那么在城市各部门pass ordinance不就没用了吗。我想的是consumer(个体），department(政府部门）
E：如果department不能树立好榜样的话，个体和企业也就不会curtial,效果就没有了。
是不是D和E没有着眼于具体措施，而题目只要看curtail usage就可以了呢。但我又怕我实际考试无法分辨！请大家指教

去非削弱，D选项去非后，是住户引起的最近的用量增加，减少department的用量，用于满足用户，也还是可以维持meet future usage呀～E选项还是一样的，取非后还是没办法削弱原结论。所以都不能是assumption，个人觉得D和E应该是属于加强选项，不是assumption。

同意！我之前没有想到还可以维持usage~
