PARAGRAPH 3：
Most consumer-goods markets are significantly different.
Typically, there are many rather than few potential customers. Each represents a relatively small percentage of potential sales. Rarely do members of a particular market segment group themselves neatly into a meaningful program target. There are substantial differences among consumers with similar demographic characteristics. Even with all the past decade’s advances in information technology, direct selling of consumer goods is rare, and mass marketing—a marketing approach that aims at a wide audience—remains the only economically feasible mode. Unfortunately, there are few media that allow the marketer (one that deals in a market; specifically: one that promotes or sells a product or service)to direct a marketing program exclusively to the program target. Inevitably, people get exposed to a great deal of marketing for products in which they have no interest and so they become annoyed.

6.The passage suggests that which of the following is true about the marketing of industrial products like those discussed in the third paragraph?
(A) The market segment and program target are identical.
(B) Mass marketing is the only feasible way of advertising such products.（A）
(C) The marketing program cannot be directed specifically to the program target.
(D) More customers would be needed to justify the expense of direct selling.
(E) The program audience would necessarily be made up of potential customers, regardless of the marketing approach that was used.

请问A的原文定位在哪里？B不对是不是因为原文是说economically feasible 而B选项中说feasible,还有就不是推论出来的？
请问这句话是否是A选项的定位呢？Rarely do members of a particular market segment group themselves neatly into a meaningful program target.  还麻烦问一下，这句话怎么翻译理解？

These three groups are rarely identical. An exception occurs occasionally in cases where customers for a particular industrial product may be few and easily identifiable. Such customers, all sharing a particular need, are likely to form a meaningful target, for example, all companies with a particular application of the product in question(market segment，这可以根据原文对于market segment 的定义得出： First, there is the marketsegment(部分)—peoplewho need the commodity(商品) inquestion.   ), such as high-speed fillers（填充物） of bottles at breweries（啤酒场）. In such circumstances, direct selling (marketing that reaches only the program target) （这里则对应的是the program target) is likely to be economically justified, and highly specialized trade media exist to expose members of the program target—and only members of the program target—to the marketing program.
