27．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。

注意原文是　the XT chain of gasoline stations ，不是gasoline stations ，部分不能代表整体。

淡蓝色的回忆多谢回复，有几问. 我觉得，c比a 好。a是对总体的描述，与个体无关。c则表示促销无效。人们只是少买几次，但多卖量。总体不变。

如果将C中的

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?

改为many，则应该选择C

如果原题没有many, 就只有选A（因为选A附加了某些推理假设）。

如果将C中的any改为many，则应该选择C

3.Were there any customers(注意这里是复数) 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?

如果原题没有many, 就只有选A（因为选A附加了某些推理假设）。

highflyer

howardwang, 谢谢，同意，c是由有点问题，不过，考试时肯定中，太细了。A一看就排出了。总体怎么样，与个体无关。

highflyer

Howardwang,可以解释一下A为什么对吗？我后来一想，如果C的答案是 否，一定支持，如果是 是，有一点否定的作用（只是一点）。但a无关阿

Which of the following, if true, provides evidence that most logically completes the argument below?
According to a widely held economic hypothesis, imposing strict environmental regulations reduces economic growth. This hypothesis is undermined by the fact that the states with the strictest environmental regulations also have the highest economic growth. This fact does not show that environmental regulations promote growth, however, since
A. those states with the strictest environmental regulations invest the most in education and job training
B. even those states that have only moderately strict environmental regulations have higher growth than those with the least-strict regulations
C. many states that are experiencing reduced economic growth are considering weakening their environmental regulations
D. after introducing stricter environmental regulations, many states experienced increased economic growth
E. even those states with very weak environmental regulations have experienced at least some growth

请问牛牛，那个是答案。
