以下是引用sunnysmell在2006-5-24 0:49:00的发言：

I have the same question about "C". I think C does not specify the number (maybe some/most commuter will buy 5 years token,
but that is just in our mind, you can not get it from stated information of this question), you can not tell how much C affect the plan,
but D gave out the number "20%".
Both C and D weaken the effectiveness of the plan, but D is better. Just as the OG's explanation: B and C would not have a
significant impact.

我觉得应该这样考虑:C说的是很多人选择预购5年的现价月票,这就是说还是交钱了,只是没有多交

而D说的是20%的人改走另一条路了,这样就连钱都不交了,更别说多交了,所以D更有影响,也响应了OG的解释.

突然想起来了,XDF的FF讲过这道题

他的解释:因为D中有通勤者会转到其他的路上去,那就相当于给现在这条路上的drivers腾地方了，就是对它们benifit的．

because it would unfairly force drivers to absorb the entire cost of something from which they receive no

benefit.

就怀疑前提了（怀疑前提就是怀疑了结论的可靠性－－－ＬＡＷＥＲ）

这样想完全错误！注意这道题的问题是“哪个选项weaken这个计划在财务上的有效性”，而不是问“哪个选项weaken这个计划不公平的结论（weaken反对这个计划的意见）”。注意和后面一题的问题比较。

首先token是代币的意思，就是说你先买个token，下次过桥的时候用上次买的token就可以过桥了。

其次，注意问题问的是财务上的有效性，所以收支相减，赢利越多就越有效。

(A) Before the authority increases tolls on any of the area bridges, it is required by law to hold public hearings at which objections to the proposed increase can be raised. //在听证会这个计划被反对，也许这个计划不能实施，并不weaken这个计划在财务上的有效性

(B) Whenever bridge tolls are increased, the authority must pay a private contractor to adjust the automated toll-collecting machines. //这个属于一次性投资，对预期收益没有什么大的影响。

(C) Between the time a proposed toll increase is announced and the time the increase is actually put into effect, many commuters buy more tokens than usual to postpone the effects of the increase. //token的购买属于短期行为，对于题目中五年的计划没有影响。这个选项，好像很多人有疑问。有提出可以购买五年的代币。首先，这个想法太极端，不怎么符合常识。其次选项中也提及postpone the effects of the increase，所以只个短期行为！

(D) When tolls were last increased on the two bridges in question, almost 20 percent of the regular commuter traffic switched to a slightly longer alternative route that has since been improved. //少了20%的人，少了五分之一的收入，当然很大的影响了收入。另外注意选项中是过去时，是说上次增加了过桥费，就少了20%的人，那么这次很可能产生同样的效果，甚至少更多人。

(E) The chairman of the authority is a member of the Tristate Automobile Club, which has registered strong opposition to the proposed toll increase. //反对意见无法weaken计划的财务有效性。

以上分析来自对OG11的理解。

楼上说的有道理，我也比较昏这题。不过，如果比较C\D，从算术的方法来看，真的还是D亏得更多啊。B我觉得是无关选项，因为revenue是指收入，与成本无关，而投资属于成本。

呵呵，这么分析，那么D就是最好的选项了。

C和D都weaken，哪个更weaken就要看感觉了~~~~
