一道逻辑题-->pumpkin转移

如你所说：“我选了C,因为我觉得C说的目的和原文的目的to satisfy wants不一样,”

所以，c是从刚开始的地方就否定了the function of government, 所以是断桥的做法啊

至于d选项，题目中说是dispensiable，选项中说not sufficient，这样并不矛盾啊，相当于必要但是不充分

楼主最好指明出处，谢谢

Ｄ　言论自由不能完全满足公众的愿望，由此，社会秩序也显得很重要。

可看出Ｄ　在支持题干结论的基础上，进一步提出了社会秩序，因此not undermin the conclusion.

第一次做LSAT, 想练练速度. 可能是很早前做过FEIFEI,有的题有点印象,错25题错5个,时间39分钟.不好, 不过感 ...

Spot the question type: Weaken ( Except )

Object: Weaken the conclusion of the argument

Core of the argument:

Function of gov ---> Satisfy the genuine wants of the masses ---> can satisfy those wants ---> be informed what are those wants ---> Freedom of the speech ---> indispensable for a healthy state

A. If people do know know what they want, how could they inform the government of what they want ? ---> weaken

B. Freedom of speeches ---> No wants of the masses ---> No Social order

Great concept, by having the freedom of the speeches as the sufficient condition to lead to a healthy state, it also lead to the other necessary condition as the negate of the sufficient condition of leading to one of the negate sufficient condition ( wants of the mess ) not be able to guarantee the indispensable for a healthy state.

Weaken perfectly.  

C. If it is true, then we know all of the conditional logic chains could be destroyed here.


D. The other good concept here.

1. Freedom of the speech is actually the necessary condition of  " satisfying the wants of the masses " so, being correct that it is not sufficient. Meanwhile, it said that in order to be sufficient it has to be that ( Freedom of speech + Social order ---> satisfying the wants of the masses ).

So, from the original argument we know that ( Satisfying the wants of the masses ---> Freedom of speech ), then we know that D is actually not weakening the original argument but to explain why freedom of speech is necessary to satisfy the wants of the masses ) - Not weaken at all.

E. If they know what people want, they don't need to be informed.
