GWD32-Q8
Last August the XT chain of gasoline stations had a temporary sales promotion in effect. In the promotion, any customer who made a purchase of ten or more gallons 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 in August the previous year, so evidently the promotion was successful as a means of boosting sales.
In evaluating the argument, it would be most helpful to answer which of the following?
A.   In the areas in which XT’s gasoline stations operate, how did total combined gasoline sales for all gasoline stations last August compare with sales for the previous August?
B.   Was the money that XT earned from the increase in gasoline sales enough to offset the cost of providing free car washes during the promotion?
C.   Were there any customers who bought ten or more gallons at an XT gasoline station during the promotion who would have or more gallons at an XT gasoline in lower quantities, but more frequently, if the promotion had not been in effect?
D.   Did XT or any of its gasoline stations have to pay other businesses to provide the car washes that customers were offered in the promotion?
E.   Are XT’s gasoline sales in August usually significantly higher than one twelfth of XT’s annual gasoline sales?

本题答案是A
我选的是E，因为我觉得E的答案如果回答是yes的话，说明sales提高与该promotion 无关，如果回答是no的话，说明sales 提高与该promotion有关

后来搜索了一下论坛，发现有位大牛曾经说过E项的比较点错误，我就不明白拉...能再说详细点吗？

E的话如果8月普遍在历史上都比其他月高，那么今年8月比去年8月高不是一样还是可以说明promotion对sales有刺激么？这一题argument的关键点是今年8月的升高不是一种普遍的升高，即不是其他店也都升高了，这样才能体现promotion的特殊性

题目说的是今年8月和之前8月的比较不是8月份跟年度内其他月份的比较所以比较点是错的无关
