Vitacorp, a manufacturer, wishes to make its information booth at an industry convention more productive in terms of boosting sales. The booth offers information introducing the company’s new products and services. To achieve the desired result, Vitacorp’s marketing department will attempt to attract more people to the boost. The marketing director’s first measure was to instruct each salesperson to call his or her five best customers and personally invite them to visit the boost.
Which of the following, if true, most seriously weaken the predication that the marketing director’s first measure will contribute to meeting that goal of boosting sales?

A.    Customers who participate booth are those not satisfied with Vitacorp products and will use this opportunity to express their unsatisfaction.
B.    Many of Vitacorp’s competitors have made plans for making their own information booths more productive in increasing sales.
C.    An information booth that is well attended tends to attract visitors who would not otherwise have attended the booth.
D.    Most of Vitacorp’s best customers also have business dealings with Vitacorp’s competitors.
E.    Vitacorp has fewer new products and services available this year than it had in previous years.
选A
我的问题是：题设说主管要求销售人员邀请5个best customers 。但是A说这些参加booth的customers都是对产品不满来发牢骚的。我认为A与所给条件矛盾所以当时就排出了。请问，这应该怎么理解？谢谢回复~

其实很简单，搂主想象一下：如果销售人员邀请的客户中，只有那些来发捞骚的来到了 information booth，而真正有潜在需求的客户没有来，主管的要求显然是达不到的。
