15) The following memorandum is from thebusiness manager of Happy Pancake House restaurants.
Recently, butter has been replaced bymargarine in Happy Pancake House restaurants throughout the southwestern UnitedStates. This change, however, has had little impact on our customers. In fact,only about 2 percent of customers have complained, indicating that an averageof 98 people out of 100 are happy with the change. Furthermore, many servershave reported that a number of customers who ask for butter do not complainwhen they are given margarine instead. Clearly, either these customers do notdistinguish butter from margarine or they use the term 'butter' to refer toeither butter or margarine.
Write a response in which you discuss oneor more alternative explanations that could rival the proposed explanation andexplain how your explanation(s) can plausibly account for the facts presentedin the argument.

非常感谢！






Theauthor's claim, based on what really happened in the restaurant after thechange from butter to margarine, although at first glance is plausible, thereare more than one alternative explanations that can rival author's.




The author concluded the change has had little impact on the customerssince there were only 2 percent of customers who have complained about thechange. However, some reasonable explanations may be alternative. The first oneis that perhaps not all the customers have ordered the butter since the change,and they might even not know the change. Therefore, the number of complainsmight increase greatly after most of the regular customers have ordered thebutter which means none of the authors explanations is right.




  And the second alternative one is that, not all the customers want tocomplain about the change in that they think the change is not a big deal, andthey do not like to waste the time and energy to talk to restaurant about it.What's more, they may think the new butter is delicious, which can totally takethe place of the last one so that they do not complain about it.




   Another explanation will cast doubt on the reliability of the resultsfrom the servers. There is no official survey or test to record the responsesfrom customers, and there may be some mistakes and deviations in the answersfrom the servers. There is a big possibility that servers may want to reducethe complicated change any more and they choose to keep silence aboutcomplains. Another possibility is that servers do not care about the customersresponses, and they may just forget and underrate the discontents fromcustomers. So the author's claim that customers do not distinguish butter frommargarine or they use the term 'butter' to refer to either butter or margarineis not the only two explanations available.




  In order to make the memorandum more reasonable, the author should takefully considerations before making a conclusion. By adding what have beendiscussed above, the argument may be more convincing.

southwestern UnitedStates   不代表全部地区的顾客
only about 2 percent of customers have complained, indicating that an averageof 98 people out of 100 are happy with the change
这个情况有可能 是 那98%不愿意头绪觉得麻烦或者决定下次再也不买了
Furthermore, many servershave reported that a number of customers who ask for butter do not complainwhen they are given margarine instead
同上
Clearly, either these customers do notdistinguish butter from margarine or they use the term 'butter' to refer toeither butter or margarine
不能因为他们不投诉就说他们不知道区别。

还有就是 如果。里面有说：调查显示。。那你就要质疑  
这个调查是谁做的？有没有第三方权威证明？
调查途中有没有问题涉嫌误导被调查者
。。。
这个里面也可以质疑 这个2%的调查 是谁给的

这是个套路
还有就是地区 部分地区的情况不能代表全部的情况
