Q17:GWD32-Q8
             BA

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 tree 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?

B, Money talks

我认为答案应是A。请注意结论: Evidently the promotion was successful as a means of boosting sales. 这里要评估的是，这个promotion在促进销售量上是否成功，而非在促进利润上是否成功。如果free car wash的支出比销售量增加带来的收入还多，那这个promotion不是一个成功的增加利润的方式，但不能证明它不是一个成功的促进销售量的方式。所以B不正确。

agree with A

B only talk about whether the revenue cover the cost, doesn't mention about the promotion.

A compare the revenue WITH promotion and WITHOUT promotion, so its the answer.

支持simon观点，问题关键在问题本身，题目说的是boosting the sales

A, B 是很典型的有关无关的choices. B: profits, A. sales/revenue. 文章结论是讲sales's result. ==> A

结论: so evidently the promotion was successful as a means of boosting sales .

结论是针对sales而不是profit提出的.这里C才是个很强的干扰项.

A:XT所在地区的加油站总的汽油销量去年和前年相比.

C:如果XT没有促销,那些现在买了ten or more gallons汽油的顾客,其中是不是有人会买更少的量,但是买得更勤. (因为超过ten gallons才有free car wash)

这两个选项都和evaluation的结论相关.

A:如果地区的汽油销量去年比增加很多(>10%),说明他因可能导致XT的汽油销量增加.而不是promotion.否则,promotion有效.

C:干扰项.C不能evaluation在于"where there any",是否存在这类顾客并不能衡量promotion的效果.要衡量的话,必须要用这类顾客占全部顾客的比例.如果绝大多数的顾客都每次加更多油,加的次数比以前少.才会影响promotion的效果.

选了C，

居然把A看成重复题目的前提信息了，没注意到时当地所有的加油站销量。。。。
