LastAugust the XT chain of gasoline stations had a temporary sales promotion ineffect. In the promotion, any customer who made a purchase of ten or moregallons of gasoline was entitled to a free car wash. For the month of August,XT experienced a ten percent increase in gasoline sales as compared to sales inAugust the previous year, so evidently the promotion was successful as a meansof boosting sales.
Inevaluating the argument, it would be most helpful to answer which of thefollowing?
A. In the areas in which XT’s gasoline stationsoperate, how did total combined gasoline sales for all gasoline stations lastAugust compare with sales for the previous August?
B. Was the money that XT earned from theincrease in gasoline sales enough to offset the cost of providing free carwashes during the promotion?
C. Were there any customers who bought ten ormore gallons at an XT gasoline station during the promotion who would have ormore gallons at an XT gasoline in lower quantities, but more frequently, if the promotion had not been ineffect?
D. Did XT or any of its gasoline stations haveto pay other businesses to provide the car washes that customers were offeredin the promotion?
E. Are XT’s gasoline sales in August usuallysignificantly higher than one twelfth of XT’s annual gasoline sales?

答案是A，可是我怎样想都是C对啊

A讲的是包括XT在内的所有加油站的销量，今年8月和去年8月的对比。我认为靠这个是无法判断促销是否会给XT带来销量的增长。即使XT的销量增幅远远大于整体市场，也有可能是因为XT一直以来就是市场上的best performer。而且A选项根本没提到promotion，很明显没有办法得出任何和promotion相关的结论。
C很直接的点明了promotion的作用只是改变了消费者的消费模式，从少量多次变成了一次多量，并没有增加销量。尽管没有给出其他促进销量增长的原因，但已经可以判断promotion的作用并不在刺激销量。

还请各位帮忙看看，多谢！

和老婆讨论了一晚上，还是没有结论，还请版上的NN们不吝赐教！

楼主：你好，首先请你不要假定答案中一定会出现PROMOTION，答案没有那么白痴的。
AC区别在哪里，A说的是SALES比较的问题。C说的是CUSTOMER的性质问题，显然A相关，杀C。
另外，原文问的是支持!

多谢呵，可是你也只是从选项的内容来做判断啊，如果从逻辑角度呢？

我后来想了半天，C能够让我觉得不足的地方只是它说的是“any customers"，不具有代表性，所以无法说明问题。。。

我咋觉滴是B捏。。。。。。。。。。。

哦哦懂了题的结论是evidently the promotion was successful as a meansof boosting sales.

C中说有些人会买的少一点但次数多一点

我以为sales是用总revenue来衡量的所以尽管客户买的少一点次数多一点买出去的总量还是一样的所以revenue没变

而A是比较两个8月的revenue 所以是对的。

LZ懂了么？

按LZ的话来说少量多次和一次多量那总的销量是一样的？但是题目说了sales涨了啊不是矛盾的嘛

我想我知道楼主绕在那里了。
这个销量增加是一个已经存在的事实，而为什么导致销量增加是逻辑的主线。
1－楼主认为C会导致销量没有增加，否定了事实。这样本身就不对。
2－换一个角度，消费者本来打算分几个月买汽油，这回一下全买了，也说明promotion起了作用。
这个题把选项取非，取正，看看是不是分别weaken和support原来的结论。

不知道说清楚了没有
