  Among the more effective kinds of publicity that publishers can get for a new book is to have excerpts of it published in a high-circulation magazine soon before the book is published. The benefits of such excerption include not only a sure increase in sales but also a fee paid by the magazine to the book's publisher.
Which of the following conclusions is best supported by the information above?

(A) The number of people for whom seeing an excerpt of a book in a magazine provides an adequate substitute for reading the whole book is smaller than the number for whom the excerpt stimulates a desire to read the book.

(B) Because the financial advantage of excerpting a new book in a magazine usually accrues to the book's publisher, magazine editors are unwilling to publish excerpts from new books.

(C) In calculating the total number of copies that a book has sold, publishers include sales of copies of magazines that featured an excerpt of the book.

(D) The effectiveness of having excerpts of a book published in a magazine, measured in terms of increased sales of a book, is proportional to the circulation of the magazine in which the excerpts are published.

(E) Books that are suitable for excerpting in high-circulation magazines sell more copies than books that are not suitable for excerpting.

答案是A

E怎么不对了？

文中说：excerpts on the high-circulation magazine-->not only a sure increase in sales but also a fee paid by the magazine to the book's publisher

可以推出：excerpt能刺激人们去购买。

所以A对啊。

E，首先文中根本就不是在谈论suitable 还是不suitable的问题。因为文中是说excerpt带来的好处。

   而且suitable 比not suitable sell的好，这个推不出来。文中比较的是，同一本书，excerpt 比不excerpt的好。如果按E的推理，那就太绝对了，好像只要excerpt就一定比其他的不excerpt的好。
这是我的理解。
