Unlike the wholesale price of raw wool, the wholesale price of raw cotton has fallen considerably in the last year. Thus, although the retail price of cotton clothing at retail clothing stores has not yet fallen, it will inevitably fall.
Which of the following, if true, most seriously weakens the argument above?
The cost of processing raw cotton for cloth has increased during the last year.
The wholesale price of raw wool is typically higher than that of the same volume of raw cotton.
The operating costs of the average retail clothing store have remained constant during the last year.
Changes in retail prices always lag behind changes in wholesale prices.
The cost of harvesting raw cotton has increased in the last year.

类比推理
生棉花的批发价下降了------棉衣服的零售价也下降 削弱给出二者区别，或第三方示例
A 加工棉花的成本上升了，自然价格不可以下降 给出了二者区别
B 不关心wool
C 运营成本不变 没有给出区别
D 滞后 那就说明有可能也下降 加强了
E 收割生棉花的成本上升了，但premise已经说了生棉花的价格下降，让我们反驳棉衣服的价格不会下降。这个谈论前提无意义
不是类比 根本不用管 raw wool
