When a cityexperiences a sharp decline in population, the city's tax revenues, which payfor such city services as police protection and maintenance of water lines,also decrease. The area to be policed and the number and length of the waterlines to be maintained, however, do not decrease. Attempting to make up the taxrevenue lost by raising tax rates is not feasible, since higher tax rates wouldcause even more residents to leave.

一个城市如果人口出现很快的下降，城市的税收收入（用以支持警察保护盒水源的）会减少。但警察巡逻和水源领域的工作领域不会减少。为了弥补税收收入而去提高税率是不可行的，因为高税收会导致更多的人离开。

The information givenmost strongly supports which of the following general claims?

A. If, in a city with sharplydeclining population, police protection and water line maintenancedo not deteriorate, some other service previously provided by the city willdeteriorate or be eliminated.

B. If a city's tax rates are held stable overa period of time, neither the population nor the levels of city servicesprovided will tend to decline over that period.

C. If a city's population declines sharply, policeprotection and water line maintenance are the services that deteriorate mostimmediately and most markedly.

D. A city that suffers revenue losses because of asharp decline in population can make upsome of the lost tax revenue by raisingtax rates, provided the city's tax rates are low in relation to those of othercities.

E. A city that is losingresidents because tax rates are perceived as too high by those residents canreverse this population trendby bringing its tax rates down to a more moderatelevel.

我是这么理解的：
support：不能用升税率来提高税收==为什么不能？可能是提升税率会带来哪些危害
A. 提升了税率之后，尽管警察啥的（原文要保护的两个方向）没有被破坏，但是其他的方面会被破坏——OK，说了提升税率的危害，留着
B。税率保持则行业不会受到破坏===原文谈的是提高税率，和税率保持有什么关系？换句话说，即使保持税率时没有影响，那难道税率变动就会有影响吗  我认为这是一个无关选项，这就像是我有ABC三个选择，我想论证A不能实现计划，你告诉我B对计划没有害处
