LSAT-5-6-20 求助NN!!

20. Politician: Homelessness is a serious social problem, but further government spending to provide low-income housing is not the cure for homelessness. The most cursory glance at the real-estate section of any major newspaper is enough to show that there is no lack of housing units available to rent. So the frequent claim that people are homeless because of a lack of available housing is wrong.

That homelessness is a serious social problem figures in the argument in which one of the following ways?

(A) It suggests an alternative perspective to the one adopted in the argument.

(B) It sets out a problem the argument is designed to resolve.

(C) It is compatible either with accepting the conclusion or with denying it.

(D) It summarizes a position the argument as a whole is directed toward discrediting.

（C）

(E) It is required in order to establish the conclusion.

不知道是不是我对答案的理解方式有问题？我理解下来文章是就HOMELESS的一个改善方案进行了反驳，那么为什么正确答案的C中有说“accepting the conclusion ”呢？很费解！恳请牛牛释疑。

not NN, just want to help.

the author just trying to deny a housing program. according to his reasoning, no matter the firsrt sentence is true or false the conclusion he draws is valid. that is what C said.

'Homelessness' is the backgroud of the argument. It justifies the discussion of a particular programme. But  homelessness as being a social problem, by itself, doesn't constitute any part of the argument against the govermental programme made by the politician. It's a problem to solve. whether or not providing low-income housing is a good social programme, it still needs to solve. Thus it's compatible with either accepting... or denying....

A similar question:

Political commentator D: 在C国, 蚊子成灾，是一个严重社会问题。问解决这一社会问题，C国政府提出一个解决方案：给蚊子戴避孕套或节育环或实施接扎手术。但是，咨询任何一个科学家（生物学家和经济学家），他们都认为这个不仅技术上尚几乎不可行，即便可行也是不经济的。所以，哪种流行的观点--蚊子之所以成灾，是因为我们没给它们戴避孕套或节育环或实施接扎手术--是错误的。

Question: 这一论点-- 蚊子成灾是一个严重社会问题--在Political commentator D's 评论中起啥作用？
