Downtown Villieu was once a flourishing business district,but most Villieu-area businesses are now located only in the suburbs.The office buildings downtown lack the modern amenities most business operators demand today.To lure more businesses downtown,Villieu officials plan to have several modern office buildings constructed and to offer reduced local tax rates to any business that leases space in a new downtown building.
Which of the following,if true,most threatens the plan's likelihood of success?
(A) Most of the businesses currently located in downtown Villieu have long-term leases on the space they occupy there.
(B) The existing office buildings in downtown Villieu have,on average,a much higher vacancy rate than do office buildings in Villieu's suburbs.
(C) The local tax rates in Villieu's suburbs are significantly lower than downtown Villieu's proposed rate for businesses that lease space in the new office buildings.
(D) Most of the businesses that currently lease office space in downtown Villieu also lease office space in Villieu's suburbs.

逻辑链：
一.downtown的office building当前不具备吸引力
二.通过1.在downtown 新建 building
2.降低 这些新建building里的bussiness的tax rate
三.吸引更多的bussiness进驻downtown
四.从而使downtown bussiness 数量提高
问题：if ture---威胁议案的成功性
即等同于：弱化上述逻辑链
A:从逻辑链可以看出,最终目的是提高downtown bussiness的数量,与本来就在downtown里的企业是否进驻新的building无关.
B：downtown里已有的office building的闲置率比郊区高,这是一句重复题意的话,与逻辑链无关.
C：suburbs目前的税率比新building打算提供的新税率要低很多.
逻辑链二（2）----三,通过降低新building的税率来吸引bussiness从suburbs到downtown,但是根据C的信息,插入逻辑链中,发现弱化了二（2）到三之间的必然性.
于是,此选项对逻辑链造成弱化效果,即：if ture,降低该计划的成功率.
D：与逻辑链无关的信息
E：比较对象是VILLIEU的downtown和其他地区之间.
而逻辑链是比较VILLIEUdowntown和suburbs之间.所以此选项为无关选项.
选择C
