谢谢mindfree..
1.呵呵。。不好意思。。我是看错题目了。。。
3。 markup这里是毛利的意思吗？ 我的词典是涨幅的意思。。所以我原文看得有点怪。。现在理解了
2。还是不理解。。。
你的意思是“应选择的方案就应该是demolish”
但是我看问题问的是：
Which one of the following principles, if established would determine that demolishing the houses was the right decision or instead would determine that the proposal advocated by the opponents of demolition should have been adopted?

也就是说不一定非要demolish或者rehabilitate,而是要找到一个原则能决定demolish好还是rehabilitate好就行了。。

我对于题目3的理解：
题目问哪个原则可以确定：demolish是对的或者决定rehabilitate是对的。

(A)原则 When what to do about an abandoned neighborhood building is in dispute, the course of action that would result in the most housing for people who need it should be the one adopted unless the building is believed to pose a threat to neighborhood safety.
根据该原则，
房子对public构成了威胁只是the course action(rehabiltate) 不可接受的必要条件。但不是充分条件，所以无法确定rehabiltate是否ok

(B) When there are two proposals for solving a neighborhood problem, and only one of them would preclude the possibility of trying the other approach if the first proves unsatisfactory, then the approach that does not foreclose the other possibility should be the one adopted.
根据原则，保持房子是unsatifactory的，可以确定demolish是可接受的
选B

(C) If one of two proposals for renovating vacant neighborhood buildings requires government funding whereas the second does not, the second proposal should be the one adopted unless the necessary government funds have already been secured.
根据C原则，政府提供资金只是 不需要政府资金的方案(demolish)的不可行性的必要条件。。
同A一样，不是充分条件。。所以无法确定何钟方案优秀。
(D) No pain for eliminating a neighborhood problem that requires demolishing basically sound houses should be carried out until all other possible alternatives have been thoroughly investigated.
all other possible alternatives investigated是demolish成立的必要条件...
所以和A 一样。。无法确定
(E) No proposal for dealing with a threat to a neighborhood’s safety should be adopted merely because a majority of the residents of that neighborhood prefer that proposal to a particular counterproposal.
E的意思是仅仅因为大多数人喜欢某个意见并不是某个涉及安全的方案(demolish)成立的充分条件。所以也无法判断...

所以，本题考的是充分条件和必要条件。。。ACDE都是必要条件
