Bookstore owner: Consumers should buy books only from an independent bookstore, not from a bookstore that belongs to a bookstore chain. An independent bookstore tends to carry a much wider variety of books than does a chain bookstore, so because chains often threaten the existence of independent bookstores, they tend to reduce the variety of books available to consumers.
Which one of the following principles, if valid, most helps to justify the bookstore owner’s argumentation?
(A) Chain bookstores should not force independent bookstores out of business when doing so would reduce the variety of books available to consumers.
(B) Consumers should buy books from only those bookstores whose existence does not tend to reduce the variety of books available to consumers.
(C) The best interest of the bookselling business is not served when consumers purchase books from businesses whose existence tends to reduce the variety of books available to consumers.
(D) Consumers should not make purchases from any bookstore that deliberately forces competing bookstores out of business.
(E) If consumers have no access to any independent bookstore, they should buy books from the chain bookstore with the greatest diversity of books.
EXPLANATION FROM Fox LSAT
The bookstore owner’s conclusion is, “Consumers should buy books only from an independent bookstore, not from a chain.” Why does the bookstore owner say this? Well, “They tend to reduce the variety of books available to consumers.” Okay, but what if I simply don’t give a **** about variety? What if I just want to buy the latest
Twilight drivel, like I always do, and go home? In that case, what good would it be to go to the independent bookstore if Barnes and Noble is sure to have what I really want?
When a question asks you to “most justify” an argument, what that means is, “Find an additional piece of evidence that, if true, would
most prove the conclusion of the argument to be true.” I started out by arguing (like I always do). I found a potential flaw in the argument: what if people don’t care about variety? So now, to strengthen the argument, I’ll basically say the
opposite of the weakness I identified. My prediction is, “Consumers should take actions that will lead to the greatest available variety.” If that’s true, and if the evidence is true (chain bookstores reduce variety), then the conclusion of the argument, “Consumers should shop at independent bookstores,” would also have to be true.
A) The argument is about what
consumers should do, not what bookstores should do. There’s no way this can be the answer.
B) Aha! This is exactly what we predicted. I’ll read C through E just to be sure, but I’m 99% positive this is our answer.
C) The argument is not about “the best interest of the bookselling business.” The argument is about what
consumers should do. No way.
D) This is tricky, but the argument never said that chain bookstores “deliberately” force independent stores out of business. So this can’t be it.
E) This doesn’t do anything at all, because this answer would only apply to consumers who have no access to an independent bookstore. The facts never said anything about whether consumers had access or not, so this is irrelevant.
Our answer is B.
