Marketing consultant: Last year I predicted that LRG' s latest advertising campaign would be unpopular with customers and ineffective in promoting new products. But LRG ignored my predictions and took the advice of a competing consultant. This season' s sales figures show that sales are down and LRG' s new products are selling especially poorly. Thus, the advertising campaign was ill conceived. The marketing consultant's reasoning is most vulnerable to criticism on the grounds that ['it confuses a condition necessary for increasing product sales with a condition that will ensure increased sales', "it takes for granted that LRG's sales would not have been lower still in the absence of the competitor's advertising campaign", "it fails to consider that economic factors unrelated to the advertising campaign may have caused LRG's low sales figures", "it takes for granted that in LRG's industry, new products should outsell established products"]
