125. 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?

    

(A) The cost of processing raw cotton for cloth has increased during the
last year.

    

(B) The wholesale price of raw wool is typically higher than that of the
same volume of raw cotton.

    

(C) The operating costs of the average retail clothing store have remained
constant during the last year.

    

(D) Changes in retail prices always lag behind changes in wholesale
prices. A

    

(E) The cost of harvesting raw cotton has increased in the last year.
正确答案是A,我选的是C,我觉得我的错误是出现在那几个price地解释上面。哪个好心人帮我解释一下啊？谢谢了~!

wholesale price；operating costs of the average retail clothing store;     the cost of processing raw cotton

我的理解分别是：批发价；商店的平均运营成本； 原材料加工费

所以按照我的理解若要说明价格不会下降应该是平均运营成本不变啊~不明白~恳请高人指点~谢谢~

The retail price of cotton clothing consists of: 1)the wholesale price of raw cotten 2) the cost of processing raw cotton for cloth and maybe 3) the operating costs of average retail clothing store

C means that 3) remain constant, that is , did not change, so it will not weaken the argument...

A means that 1) has increased, it will weaken the argument that the retail price of cotton clothing will inevitable fall.
