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.
我认为是方案推理
argument：由于price gap越来越大，所以消费者从brand转向了超市生产的。措施：brand降低这个gap
目标：能够attract these consumers back
B 好的点在于 其提及了argument的质量问题，意味着quality不是影响这部分消费者选择的cereal的因素，只有价格才是，只要gap存在，就不会switch back
C target的点错误，target的点是没有switch的消费者，但本文的目标客户是是已经switch了的消费者
D 解释了超市cereal为什么低价的原因，方案是减少gap，D最多能攻击方案，但并不能攻击到目标
