　　In an advertising experiment, Big Board, Inc. displayed the name and picture of a . little-known athlete on several of its local billboards over a 3-month period. Because the experiment increased recognition of the athlete's name, Big Boards now argues that local companies will increase their sales if they advertise their products on Big Board's billboards. This argument is unconvincing for two important reasons.

      The main problem with this argument is that the advertising experiment with the athlete shows only that name recognition can be increased by billboard advertising; it does not show that product sales can be increased by this form of advertising. Name recognition, while admittedly an important aspect of a product's selling potential, is not the only reason merchandise sells. Affordability, quality, and desirability are equally, if not more, important features a product must possess in order to sell. To suggest, as Big Board's campaign does, that name recognition alone is sufficient to increase sales is simply ludicrous.来源：考试大

      Another problem with the argument is that while the first survey—in which only five percent of 15,000 randomly-selected residents could name the athlete—seems reliable, the results of the second survey are questionable on two grounds. First, the argument provides no information regarding how many residents were polled in the second survey or how they were selected. Secondly, the argument does not indicate the total number of respondents to the second survey. In the absence of this information about the second survey, it is impossible to determine the significance of its results.

      In conclusion, Big Board's argument is not convincing. To strengthen the argument, Big Board must provide additional information regarding the manner in which the second survey was conducted. It must also provide additional evidence that an increase in name recognition will result in an increase in sales.
