24. Although all contemporary advertising tries to persuade, only a small portion of contemporary advertising can be considered morally reprehensible. It nevertheless follows that some attempts at persuasion can be regarded as morally reprehensible.

Which one of the following, in its logical features, most closely parallels the reasoning used in passage?

(A) None of the chemicals used for cleaning the Sistine Chapel will affect the original dyes. Hence, the colors used by Michelangelo will be fully restored.

(B) Not all operational tracking studies are conducted to illustrate exact corporate returns on investment. Hence, some of these studies are not reliable.

(C) A good manager always makes important decisions on the basis of adequate data, although of course some managers fail to do this. It follows that some managers are not good managers.

(D) There is a direct correlation between the number of times you repeat something and the degree to which you retain it. Therefore, repetition is always a critical factor in remembering.

(E) Some short poems are thematically pluralistic, since some sonnets are characterized by such pluralism, and all sonnets are short poems.

答案：E

还是帮我分析一下思路和推理过程吧。有点晕：）

原文：all。。。a small portion of（相当于some）。。。,所以some。。。

E：al。。。some。。。所以some。。。

我自己的问题，当时对原文的理解很清楚了，当时居然没觉得“and all sonnets are short poems”是和“some sonnets are characterized by such pluralism”并列在since里面。太过了。
