TN7-Q8:
Many large department stores in Montalia now provide shopping carts for their customers. Since customers using shopping carts tend to buy more than those without shopping carts, most of these stores are experiencing strong sales growth, while most other department stores are not. Therefore, in order to boost sales, managers of Jerrod’s, Montalia’s premier department store, are planning to purchase shopping carts and make them available to the store’s customers next month.
Which of the following, if true, casts most doubt whether the managers’ plan, if implemented, will achieve its goal?
首先还是看题目条件：
(1)M地很多大型商场现在都为顾客提供手推车
(2)用手推车的顾客倾向于买更多的东西(shadow想说：难道是因为车子太空了没有购物满足感?)，所以提供手推车的这些大型商场现在sales都强力上涨，而其他的商场sales就没有上涨(或者至少没有强力上涨!)
(3)因此，J商场的经理坐不住了，决定也采购一批手推车，下个月投入使用
问：哪个选项能削弱J商场经理的决定
也就是说，题目的中心论点是：采购手推车也能让J商场的sales强力上升，而我们要削弱这一点
A.Since most customers associate shopping carts with low-quality discount stores, Jerrod’s high-quality image would likely suffer if shopping carts were introduced.
正解。本选项说了这么个事：鉴于J商场表示自己的货物都是高质量的，不同于其他的低质量折扣店，而大多数顾客认为购物手推车是低质量折扣店才会出现的东西，如果J商场也随大流，其high-quality image将会毁于一旦，所以手推车万万不能引用;我认为这就是否定了题目因果关系中的果，也就是说此因果关系会产生与其他不同的结果，故而削弱了题目中心论点。
B.Because the unemployment rate has declined to very low levels, Jerrod’s now has to pay significantly higher wages in order to retain its staff.
本选项说，因为unemployment rate无比非常低，J商场要付更多的工资给员工;跟手推车和sales木有任何关系，转移焦点，无关。
C.A number of department stores that did not make shopping carts available to their customers have had to close recently due to falling profits.
本选项说，没有手推车的商场都因为profit下降关门了，(言下之意就是：想升profit吗?想不倒闭吗?赶紧去买手推车吧!)这个选项属于加强题目论点的，所以错误。
D.Shopping carts are not very expensive, but they generally need to be replaced every few years.
本选项说手推车是不贵，但是几年就要换一次(话说这个跟sales上升有毛关系啊!);典型的转移焦点，无关选项。
E.Stores that make shopping carts available to their customers usually have to hire people to retrieve the carts from parking areas.
本选项说有手推车的商场要雇人到停车场把手推车拿回来，同上，和sales上升木有任何关系，转移焦点，无法削弱。
