9. 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.

My answer: A
It is clear that sales will increase only when A is true.
vaka, assumption is always supported by the passage and in my opinion assumption is an implicit conclusion. .
All other choices need to be stretched.
thanks

Val,

We say too much in choice D
Sales of Book proportional to the circulation of the magazine..
lets use some formal logic here
according to D...If high circulation, then high sales
BUT
if not high circulation, then may or may not be high sales..
BUT according to D.. if not high circulation magazine, the sales wont be high...thats saying too much..dont u think?

Choice A is best. A says ONE of the reasons of high sales is me.

Good enough?

Thanks
Praetorian

I would rather go with D instead of A.

Praet,wutz the official answer?

Official Answer is A

Praetorian, believe your answer is based on Akamai's lessons of formal logic? Right? I have to study it carefully.[/quote]

Yes Val ...but it will need a great eye to pick the relationships correctly

Akamai has almost covered all varaints of a logical relationship..so that will help

Thanks
