标题: 请教lsat-5-3-24

24.       Anthropologists assert that cultures advance only when independence replaces dependence—that is, only when imposition by outsiders is replaced by initiative from within. In other words, the natives of a culture are the only ones who can move that culture forward. Non-natives may provide valuable advice, but any imposition of their views threatens independence and thus progress. If one looks at individual schools as separate cultures, therefore, the key to educational progress is obvious______


Which one of the following best completes the passage?


(A) individual schools must be independent of outside imposition


(B) some schools require more independence than others, depending on the initiative of their staffs and students


(C) school system officials must tailor their initiatives for change to each individual school in the system


(D) outsiders must be prevented from participation in schools’ effort to advance(A)


(E) the more independent a school is, the more educational progress it will make


请教,E为什么不对?

扩大推理。

是吗?我觉得A太绝对了,上文只是讲了native和non-native对culture advance的影响,所以E与题干的推理更切合一些。

那你还没有习惯于纯逻辑的思维方式。 其实很多LSAT题, 关键词就一个。

这道题的关键词是only . ( can you find it in the first line)

This word actually dictates that independence be the necessary condition for culture advance.  

So, you can find the comparable expression of " must be" in A.

whether more independence can lead to more educational progress is hard to know.

It is just an another issue.

多谢555 GG了,看了多遍,也没有留意到only这个关键词。我会加倍努力培养纯逻辑思维的。

Is "only" the indicator of necessary condition in this sentence? What the difference between "only if" and "only when"?

only是表示必要条件。only if表示仅仅在---条件下,only when表仅仅在----在什么时候,都是表示必要条件

再一个E的答案是推不出来的,文章没有量化independence和progress,因此不能推出more independence--->more progress
