24.There is little point in looking to artists for insights into political issues. Most of them hold political views that are less insightful than those of any reasonably well-educated person who is not an artist. Indeed, when taken as a whole, the statements made by artists, including those considered to be great, indicate that artistic talent and political insight are rarely found together.
Which one of the following can be inferred from the passage?
(A) There are no artists who have insights into political issues.
(B) A thorough education in art makes a person reasonably well educated.
(C) Every reasonably well-educated person who s not an artist has more insight into political issues than any artist.
(D) Politicians rarely have any artistic talent.
(E) Some artists are no less politically insightful than some reasonably well-educated persons who are not artists.

为什么不选D 我个人认为D是这个题的题干的逆否命题
觉得E推不出 理由如Kevin

We can not get from the conclusion of the argument above that most politicians do not have any aristic talent. The key is the word any. It uncessarily add the extent of aristic talent or political insight.

E) is wrong because it equal politician with someone with political insights. Nowhere in the passage could you find such statement. I am not a politician. But I might have political insights.

怎么这么绕

Eleenl:
Most means a majority, possibly all.  Some means at least one, possibly all.  Therefore, "most of them are A" could be "all of them are A", hence "NOT a single one of them are NOT A", which is contrary to "some are not A."

同意sdcar2010，most和some都是包含all的，或许生活中我们默认它不包含，但逻辑上some A are B，一定推不出some A are NOT B。

The key is to read into the last sentence, which says "the statements made by artists indicate that artistic talent and political insight are rarely found together".  Rarely means less likely but not impossible.  Hence, at least one artist has political insight.

谢谢！明白了，这里才是关键啊。
D不对，偷换了概念，politician和 political insight 不一样。politician不一定有 political insight 。

Most of them hold political views that are less insightful than those of any reasonably well-educated person who is not an artist。
这句貌似就是解题的核心，我感觉是most of them...are less...than  any ......= some of them ...are not less...than some....

The statement that artists rarely have any political insight does not have anything to do with what artistic talent politician might have.

The reason is that there is no definition of politician given in the stimulus.  For that matter, a politician might be a moron or a genius or anything in-between.
