8. 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 tree 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 ?

1)      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?

2) 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?

3) 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?

4)      Did XT or any or its gasoline stations have to pay other businesses to provide

   the car washes that customers were offered in the promotion?

5)      Are XT’s gasoline sales in August usually significantly higher than one twelfth of

XT’s annual gasoline sales ?

答案是A，问题是C好像也可以艾。。。

  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?

我觉得C是指如果不实行这个促销政策的话，可能消费者购买会少量多次，即总的sales和促销时不变，从而评价促销的效果。。我觉得这里in effect是实施的意思。open to discuss...

2) 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?

应该B吧？

促销政策是：买汽油，可免费洗车。

洗车也是有成本支出的，如果客户多买汽油产生的销售利润不能Cover这个洗车的费用，那促销就没什么意义了（促销就是以尽量少的支出，吸引客户多掏钱，如果支出的钱与客户掏钱后的利润相差无几，就没意义。）！

我觉得c说的是顾客在这次促销下一次购买10加仑以上，而如果没有促销是分多次买，每次少量，但是总量还是more的。说明顾客该买多少还是多少，这个选项讨论的是购买汽油的不同方法。跟原文讨论的促销have no sense。
