Urban planner: When a city loses population due to migration, property taxes in that city tend to rise. This is because there are then fewer residents paying to maintain an infrastructure that was designed to support more people. Rising property taxes, in turn, drive more residents away, compounding the problem. Since the city of Stonebridge is starting to lose population, the city government should therefore refrain from raising property taxes.

Which of the following, if true, would most weaken the urban planner's argument?

(A) If Stonebridge does not raise taxes on its residents to maintain its infrastructure, the city will become much less attractive to live in as that infrastructure decays.
(B) Stonebridge at present benefits from grants provided by the national government to help maintain certain parts of its infrastructure.
(C) If there is a small increase in property taxes in Stonebridge and a slightly larger proportion of total revenue than at present is allocated to infrastructure maintenance, the funding will be adequate for that purpose.
(D) Demographers project that the population of a region that includes Stonebridge will start to increase substantially within the next several years.
(E) The property taxes in Stonebridge are significantly lower than those in many larger cities.

想請問這題的D, 我的思路是這樣: 既然demographes預測說未來人口會再大幅回升,那政府就可以放心raise property taxes,因為會有人來均分taxes fee,就不會compounding the problem. 對比A ---雖然也是同樣要raise taxes,但卻沒有對文章premise中(drive more residents>>>compound the problem）做任何考慮, 我反而覺得D比較完整全面,而A有一些缺陷.

請問我的推測思路哪裡有問題？想了很久還是轉不過來麻煩各位NN了

頂！

你后面问的E比较全面，前面说D，所以是D还是E？...

就D而言，增长的人口也是会不断流失的吧，所以不能很好的削弱

而A less attractive 则可以对应到drive more residents away，再顺着逻辑链削弱~

别处查了一下答案，确实是A。说一下我（大胆）的理解吧。

Urban Planner说：人口下降→税率提高→人口下降，提高税率会造成这个循环，所以不能提高税率。
要削弱这个，就要提供他因，证明 1、提高税率有别的好处，不会造成人口下降。或 2、不提高税率也会引起人口下降。

我觉得D有两个问题，1、增长是在未来时间发生的，无法解决现在的问题。从premise可以看出，调高财产税率一定会造成居民离开城市，所以不管未来人口会不会上升，因为什么原因上升，调高税率在短时间内都会造成人口的流失。2，若是真的在很近的时间内，人口就增长了，那又何必提高税率呢，毕竟提高税率的premise是人口下降。

D is very sneaky: population of a region that includes Stonebridge does not necessarily mean population of Stonebridge. What if the increasing part of the population is from areas of the region except Stonebridge?
