The only way that bookstores can profitably sell books at below-market prices is to get the books at a discount from publishers. Unless bookstores generate a high sales volume, however, they cannot get discounts from publishers. To generate such volume, bookstores must either cater to mass tastes or have exclusive access to a large specialized market, such as medical market, or both.
13. Which one of the following can be properly inferred from the passage?
(A) If a bookstore receives discounts from publishers, it will profitably sell books at below-market prices.
(B) A bookstore that caters to mass tastes or has exclusive access to a large specialized market will have a high sales volume.
(C) A bookstore that profitably sells books at below-market prices gets discounts from publishers.
(D) A bookstore that does not sell books at below-market prices does not get discounts from publishers.
(E) A bookstore that not only caters to mass tastes but also has exclusive access to a large specialized market cannot profitably sell books at below-market prices.
题中只说了，有这两种能力的书店可能获得低价，但是如果有这种能力的书店不以一个低于市场的价格卖呢，那他就不一定能获得大的市场销量。你的逻辑反了
more elabration
this is formal logic
profitly sell below market->discount from publisher->sell high volume->cater mass and/or exclusive access to specialized market
As the previous poster pointed out, B) reversed sufficient and nessary condition, it is mistaken reverse.
这句话的意思我是这样理解的： 为了达到这样的销量，书店必须如何做。 难道他的意思 不是如果这样 做了， 书店就可以达到这样的销量吗？
No.
There could very well be other conditions working together with cater to mass tastes or have exclusive access to a large specialized market to gurantee high volume sales, such as good marketing strategy, capable sales personnel on and on. The key is "cater to mass tastes or have exclusive access to a large specialized market" is nessary condition to high volume sales, not sufficient.
