Writer: I collaborated with another writer on my last book, instead of writing alone as I usually do. Because the book sold so well as a result of this joint effort, I should collaborate with a writer on my next book so that book will sell well too.
Which one of the following principles, if valid, most helps to justify the reasoning above?
(A) If a person’s book sells well because of a collaboration, that person’s next book will sell well, if he or she collaborates with the same writer.
(B) A book sells well only if its author collaborated on the book with another writer.
(C) If a person’s book sells well because of a collaboration, future collaborations on the part of that person will produce other books that sell well.
(D) Writers who do not collaborate on books have a smaller chance of writing a book that will sell well.
(E) Writers who collaborate on books, if they are good writers, usually produce books that sell well.

EXPLANATION FROM Fox LSAT
This is a surprisingly difficult question. I chose B the first time around, because I thought there was a correlation-equals-causation error at play. But looking at it again, I see that “the book sold well because of the collaboration” is a premise rather than a conclusion. So we have to accept that as fact.
The author’s conclusion basically boils down to, “If I collaborate next time, my next book will sell well.”
We’re asked to strengthen the argument. If collaboration really did cause the sales, then all we have to do to strengthen the author’s argument is find a premise that basically says, “Whatever happened in the past will happen again in the future.” Let’s see what we’ve got here.
A) This would only prove the author’s conclusion if we know that he’s going to collaborate with the same writer on his next book. We don’t know that, so this answer is probably a trap.
B) This answer says that collaboration is necessary for sales. But even if that’s true, it wouldn’t prove that the next book will sell well. If you chose this answer, you either misunderstood the flaw in the argument like I did at first, or you fell into the classic sufficient vs. necessary trap. Remember, just because San Francisco is hilly doesn’t mean that every hilly city is San Francisco. And just because every successful book is a collaboration doesn’t mean that every collaboration is successful. This ain’t it.
C) If this is true, it makes the author’s logic bulletproof. The author’s last book was successful because it was a collaboration. So the next book, if it’s a collaboration (doesn’t even matter with whom!) will also be a success. This is it.
D) This strengthens the argument, but it doesn’t prove it like C does. When we’re asked to “justify” an argument, we want the strongest piece of evidence we can find. C is better, so D is out.
E) This only applies if the author is actually a good writer. Maybe he sucks! We just don’t know. So this can’t be the answer.
Our answer is C.

Bunuel, please advise if I am correct:
(A) If a person’s book sells well because of a collaboration, that person’s next book will sell well, if he or she collaborates with the same writer. - Wrong
Selling one book well because of collaboration does not guarantee that other books will sell well as a result of collaboration.
(B) A book sells well only if its author collaborated on the book with another writer. - Wrong
No evidence in the argument that success of sales primarily depends on the collaboration with another writer.
(C) If a person’s book sells well because of a collaboration, future collaborations on the part of that person will produce other books that sell well. - Correct
Evidence: Person's book sells well because of collaboration.
Conclusion: Therefore, plan to collaborate to ensure that other book sells well too.
There is a missing link between successful sales of other book and previous book sales because of collaboration. Collaboration should ensure successful sales of book if this book is produced by the same writer.
(D) Writers who do not collaborate on books have a smaller chance of writing a book that will sell well.- Wrong
There is a correlation between collaboration and successful sales of the book, and not collaboration and writing a book that will sell well.
(E) Writers who collaborate on books, if they are good writers, usually produce books that sell well. - Wrong
Argument does not address correlation between collaboration and producing books that will sell well.
