### HideShow timer Statistics

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

The keyword here is "Since". We have to strengthen the argument:

So, we have to show the benefits of shopping at ShopperKing.

Choice B states

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

This is not a benefit of shopping at ShopperKing. In fact, it weakens the argument. Therefore, A is the correct answer as it strengthens the argument.
