求助AA 72

“Local clothing stores reported that their profits decreased, on average, for the three-month period between August 1 and October 31. Stores that sell products for the home reported that, on average, their profits increased during this same period. Clearly, consumers are choosing to buy products for their homes instead of clothing. To take advantage of this trend, we should reduce the size of our clothing departments and enlarge our home furnishings and household products departments.”

我找了两个错误:1)没有足够证据证明过去三个月发生的情况可能在未来继续延续下去
                             2)三个月时间太短,不能得出笼统的结论
请大家讨论讨论,还有什么?

可以说是clothing的cost提高了。。。导致了profit的减少而不是因为买的人少了。。。就是说除了b之外还有别的原因。。。。
