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 ______.

A. 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
B. for shoppers with more than 20 items, the ShopperKing totals averaged more than five percent higher than the FoodBasket totals
C. many shoppers consider factors other than price in choosing the supermarket at which they shop most regularly
D. there is little variation from month to month in the overall quantity of purchases made at supermarkets by a given shopper
E. none of the people who conducted the research were employees of the FoodBasket supermarket

答案是B,不懂ㄟ~求救.........

其實這一題我有作錯...
既然都問了,就解釋一下吧
觀念如不對請指證

題目只問了十幾個人
A說,顧客選擇超市,是因為它們平常買的東西,在某家超市賣的比另一家便宜
這十幾個人的抽樣不代表ShopperKing超市每樣東西都比FoodBasket超市賣的貴
可能S超市賣蔬果便宜,F超市賣肉類便宜
而在訪問中,調查對象是從F超市出來的,當然他們都因為肉便宜才去F超市買的....
所以這個調查不能代表在F超市買所有東西都比S超市便宜

hi~homaru
你的理解很正確阿~
顧客都會挑各個賣場最低價的東西下手
所以雖然S的平均價格比F高
S的客源不會因此跑去F購買 (AA)

隔了將近一年,
要跟你說,
你這解釋真妙,
要我講得那麼清楚還不太容易....

最後一句話：Nevertheless, this result does not necessarily show that shoppers at ShopperKing would save money overall by shopping at FoodBasket instead, since ______.

我不太董這一句話的意思，是說：這個結果無法絕對顯示出 ShopperKing的shoppers 在FoodBaske購物可以省錢嗎？

最後since前面的 "instead" 是不是表示取而代之的意思？

我有一點點卡在那個instead了。
請賜教！謝謝！

原題是說:消費者在 SK(ShopperKing)所購買的物品比在FB(FoodBasket)購買類似產品的價格貴5%,然而,這並不一定表示消費者在FB消費就會比在SK買省錢,因為____.

如果要把取代的意思翻出來的話,應該是說消費者"選擇FB來取代SK"來購物,大體上不見得會省錢

但是文中有一句話 為何沒人注意到? 還是其實不重要? 他說:調查對象買的東西是一樣的
"The prices of the very same items at the nearest ShopperKing supermarket were totaled and compared with the FoodBasket total."

但是文中有一句話 為何沒人注意到? 還是其實不重要? 他說:調查對象買的東西是一樣的
"The prices of the very same items at the nearest ShopperKing supermarket were totaled and compared with the FoodBasket total."

這句話只是證明,消費者會選同樣的東西,誰便宜跟誰買
換句話說,S公司一定也有別種item比F公司便宜
所以結論才說在S公司買不一定比較貴
