原题

Which of the following most logically completesthe argument?

According to experts on shopping behavior, moreshoppers would shop at Jerrod’s department store if they were offered theconvenience of shopping carts.  In fact,even if the amount spent by these additional customers only just covered thecost of providing the carts, providing carts would still probably increaseJerrod’s profits, since _______.

A. the layout of Jerrod’s is open enough toaccommodate shopping carts comfortably

B. several department stores that compete withJerrod’s have begun to make shopping carts available to their customers

C. there are some potential customers who wouldnot be enticed to shop at Jerrod’s by the availability of shopping carts

D. stores that make shopping carts available tocustomers usually have to hire people to retrieve them from parking areas

E. a customer with a shopping cart buys more, onaverage, than a customer without a cart

类比 定义为（A,B）的相同点列出来，然后再给出A的一个特点，推理B也应该具有这个特点，B的这个特点就是原文的结论。是事情具有的特点类比，而不是事情类比。

我能理解 A B 分别是 增加购物车前 和 增加购物车后   利润一样是两个的相似点。但是按照定义还要给A一个特点  推理出B也要具有这个特点  我没能发现给了A什么特点。。A都没找到特点B就更没发现了。不清楚这题怎么是类比？ 求解
