OG 11th Verbal Review CR 80 我觉得答案有问题

80. Vitacorp, a manufacturer, wishes to make its information booth at an industry convention more productive in terms of boosting sales．The booth 0ffers 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 booth．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 booth．
            

Which of the following，if true，most strongly supports the prediction that the marketing director's first measure will contribute to meeting the goal of boosting sales?

(A)  Vitacorp's salespeople routinely inform each important customer about new products and services as soon as the decision to launch them has been made．

(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．

答案是C。我觉得应该是A。booth的功能是提供产品和服务信息，那些本来不会去的人去了也不一定能增加销售，而针对公司老客户的活动不是更有效吗？不知道我这样的判断是不是带了一些个人经验，但从逻辑上好像也没觉得C跟boosting sales有什么关系，原文中没看出more visitors ，more sales的关系
