23. The function of government is to satisfy the genuine wants of
the masses, and government cannot satisfy those wants unless it is
informed about what those wants are. Freedom of speech ensures that
such information will reach the ears of government officials.
Therefore, freedom of speech is indispensable for a healthy state.
Which one of the following, if true, would NOT undermine the
conclusion of the argument?
(A) People most often do not know what they genuinely want.
(B) Freedom of speech tends ultimately to undermine social order,
and social order is a prerequisite for satisfying the wants of the
masses.
(C) The proper function of government is not to satisfy wants, but
to provide equality of opportunity.
(D) Freedom of speech is not sufficient for satisfying the wants of
the masses: social order is necessary as well.
(E) Rulers already know what the people want
答案d .我觉得c好像undermine了前提,但是并没有undermind结论啊.言论自
由言下之意是不是提供了平等的机会啊?那也同样得到结论.d因为言论自由影
响了社会秩序,倒是觉得有undermine之意.

D并没有undermine之意啊，题干说freedom of speech是healthy state的必要条件，而D说freedom of speech不是healthy state的充分条件。这句话并没有威胁到结论啊，不是充分条件并不等于不是必要条件啊。
关于C有同样的疑问，还请NN继续指点。

So you mean undermining the premises would not undermine the
conclusion? How about testing it with an example:
Dave likes Christine (premise). So he should ask her out
(conclusion). But actually Dave likes Jenna, not Christine. How is
the conclusion now?

On C,
In the argument , we got  healthy state -->function of government-->satisfying wants-->informed well-->speech freedom
Conclusion: healthy state-->speech freedom.   C undermines one part of the reasoning link -- function of government --> satisfting wants.

yeah,u r righ.but i meant c can be deduced like this:speech freedom> provide equality of opportunity>function of government>healthy state.  so the conclusion doesnot be undermined if the above deduction is right.

uniqueness

There is no reason to assume such relationships as speech freedom> provide equality of opportunity or provide equality of opportunity>function of government only based on the information given by the argument.
These are just from your common sense .
