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.

但是我想做个假设，如果在杂志上刊登摘选段落的时候，有10人会买这本书，而刊登之后有100个本来不会买书的人看到了这本杂志，但是只有一个人真的买了书，这样的情况，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 BIGGER （99：1）than the number for whom the excerpt stimulates a desire to read the book, 但是因为买书的人增多一人，11人, which cannot be the conclusion drawn from above information.

还是我有点儿晕了？

多谢多谢！

Note that A specifies that the people who chooses not to buy the book is "smaller" than the people who does, after reading the excerpt. So in your case, if 100 people read the excerpt in the magazine, at least 51 will buy the book to make the condition valid.
