57. 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.

我一直觉得应该选E,因为题目里明确说了， the benefit ...include not only a SURE increase in sales", 因此书上了高发行杂志的当然应该比没上的要卖得多。

OG的答案是A,说是看过摘录之后会买书的人比看过以后不买的人要多．这个答案我感觉有两个问题
１）这个选项感觉更像assumption，而不是conclusion
２）这个结论未必会成立，因为假设看过摘录的人有100人，然后40人买了，60人不买．这本书的销量还是比在杂志上做摘录前提高了啊．更何况从现实上来说，看过摘录的人中肯定是不买的要多吧．呵呵．

而关于E, OG11里的解释是：这个结论只是关心一本书是否适合在杂志上做摘录，题目中没有提到这点．不过我感觉E的重点不在于是否适合，而是上了杂志就销量提高，这个和我上面提到的sure increase in sales明明是吻合的．

欢迎大家指点！

E肯定不对， E中间说的是两种书（适合杂志与不适合杂志摘要的书） 的发行量的比较， 文中没有说到这点。 而且适合杂志的话出版商也不一定把他摘到杂志上。

A是可以从题目推出来的， 你的比较方法是假设不做摘要一本书都卖不出去。而且e中说的是人数不是百分比。  我们可以假设如果不上杂志， 有x人会买书欲望， 杂志的发行量很大， 可以假设x中的大部分都可以看到这个杂志。 如果其中有y人看到杂志摘要之后不想买了， 那么书的销售量就是(x-y)， 再加上原来没有购买欲但是看了杂志才有购买欲的人z， 总数为（x-y+z）。 如果y大于z， 书的发行量实际会比x小， 这样就是下降而不是上升了。

同意LS 解释,

E 中提到了没有刊登在杂志的书本, 而文中根本没有提及, 所以是 out of scope. 而且这里找的是CONCLUSION, 就是要一定正确的,
E也不一定正确, 因为文中没有说不做摘要就卖的少了, 不做摘要也可能有其他的宣传途径卖的一样多或者更多的.

我也是选了E,　应该完全忠于原文的内容，不做自己的猜测。
