Over the past five years, the price gap between name-brand cereals and less expensive store-brand cereals has become so wide that consumers have been switching increasingly to store brands despite the name brands' reputation for better quality. To attract these consumers back, several manufacturers of name-brand cereals plan to narrow the price gap between their cereals and store brands to less than what it was five years ago.
Which of the following, if true, most seriously calls into question the likelihood that the manufacturers' plan will succeed in attracting back a large percentage of consumers who have switched to store brands?
There is no significant difference among manufacturers of name-brand cereals in the prices they charge for their products.
Consumers who have switched to store-brand cereals have generally been satisfied with the quality of those cereals.
Many consumers would never think of switching to store-brand cereals because they believe the name brand cereals to be of better quality.
Because of lower advertising costs, stores are able to offer their own brands of cereals at significantly lower prices than those charged for name-brand cereals
Total annual sales of cereals-including both name-brand and store-brand cereals-have not increased significantly over the past five years.
.... the gap ... become so wide that consumers have been switching increasingly to store brands despite the name brands' reputation for better quality; 并不是说明消费者对于quality没有那么看重(我错选D、排除B的原因,认为已经despite the quality了,然而消费者这么做的原因是价格差已经过大了,因此适当地降价还是会让消费者switch回来的--除非消费者已经对低价麦片的质量满意了---故选B)
