再问GWD-12-Q40

Which of the following most logically completes the argument?

 

Researchers recently asked dozens of shoppers, chosen at random coming out of a FoodBasket supermarket, what they had purchased.  The prices of the very same items at the nearest ShopperKing supermarket were totaled and compared with the FoodBasket total.  The ShopperKing totals averaged five percent higher than the FoodBasket totals.  Nevertheless, this result does not necessarily show that shoppers at ShopperKing would save money overall by shopping at FoodBasket instead, since ______.

 

1. shoppers who shop regularly at a given supermarket generally choose that store for the low prices offered on the items that they purchase most often

2. for shoppers with more than 20 items, the ShopperKing totals averaged more than five percent higher than the FoodBasket totals

3. many shoppers consider factors other than price in choosing the supermarket at which they shop most regularly

4. there is little variation from month to month in the overall quantity of purchases made at supermarkets by a given shopper

5. none of the people who conducted the research were employees of the FoodBasket supermarket

看了原来的讨论帖 没看懂题 是说随机抽从超市里出来的人 比较他们买的东西 相同的产品价格不同 还是总价相同数量不同 完全没搞明白

LES说：偶选A。

文中最后一句话的意思是通常在SK购物的人到FB去购物未必会省钱，因为： A. 消费者通常到选定这样一个超市，他们最频繁购买的东西在那家的超市里的价格是最低的。

具体的说，假如有商品A,B,C,D,E。

在SK超市里A,B,C的价格比FB超市低。而FB超市里D,E的价格又比SK里的低。

那么假如一个消费着经常需要消费A,B,C商品，所以他会选SK超市，因为他到FB超市去买的话A,B,C反而贵，符合文中最后一句话。

但是如果是调查的从超市买东西出来的人 那么他们买的肯定就是比较便宜的产品了 便宜的还比别人贵 也是可以说明问题的啊

buying items with low prices always from one store does not mean they buy them this time(survey)

总体的价格水平S高于F，但并不是说在s买的东西（个体，一部分），换在F买就一定省钱，因为这些在S买的东西有可能恰好是S比F便宜的东西；也就是A所说的人们通常买卖场中相对其他卖场更便宜的东西。本题考察的应该是总体和个体的关系。

最后一句提到SAVE MONEY是关键，自己没看清楚，也做错了

比方说SK的大米便宜，FB的面粉便宜。总体上FB的平均价格更便宜。但是如果人们买大米一直频繁去的是SK，现在让他去FB，则不能省钱。应该就是这个意思。
