题目是: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 store has not yet fallen, it will invitaly fall.
问 Weaken 答案是 The cost of processing raw cotton for clothes has increased during last year. 我怎么觉得答案是加强啊。转不过这根筋了。。。请大牛们帮忙分析一下吧
