兩個個迷惑選項，請大家幫我排除

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

 

(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.

(E) The cost of harvesting raw cotton has increased in the last year.

B和E為什麽不可以？E和A差別在什麽地方？？多謝……

B不可以因為題目雖然說未加工棉花價格降低，但沒有足夠證據顯示同單位的未加工棉花價格比毛料來的低
E跟A差別是一個是加工棉花(加工後就不是raw cotton)一個是種or收獲棉花(收獲的是raw cotton)

好厉害，明天就考试了，逻辑还是晕晕的……

teddylydia

E為什麼不行還是沒想出來，不知是不是因為題目裡沒有提到harvest
等待高手解惑ing...
加油吧!祝明天考試順利

cost of harvesting 应该属于批发raw cotton阶段的收款,所以既然知道这个阶段的最终结果是raw cotton 价格下降,cost of harvesting与棉衣的零售价格就是无关的.E不行

題目講的是cotton clothing 的零售價會下降

A選項processing raw cotton for cloth的成本上漲,所以製成品棉衣的零售價可能會上漲.

E選項說的是收割棉花的成本上漲了,沒有A 削弱力強. 反駁E:收割成本上漲的棉花如果是用來做棉被,就無法推出棉衣的價格可能會上漲

我觉得B和E都是无关选项, 首先本题的focus是cotton原材料零售成本以及最终成品成本之间的关系,那么关于wool的成本论述跟结论无关,out of scope;

A和E的不同支出也是有关和无关的不同,A是有关,E是无关,因为从argument的范围来看是从收割棉花以后的零售价格增加开始到最终成品是讨论关心的范围,任何在这个范围内的因素的讨论都是可以接受的,但是收割棉花的成本是在这个范围之前的,就out of scope了;

类似的如果还有一个选项说倒卖的人买了以后高价卖,成本升高了......这样虽然讨论的也是成本,但是已经超出题目限定的范围了;

不知道清楚不,
