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?
A.There is no significant difference among manufacturers of name-brand cereals in the prices they charge for their products.
B.Consumers who have switched to store-brand cereals have generally been satisfied with the quality of those cereals.
C.Many consumers would never think of switching to store-brand cereals because they believe the name brand cereals to be of better quality.
D.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.
E.Total annual sales of cereals—including both name-brand and store-brand cereals—have not increased significantly over the past five years.
题目分析：A说不同的cereals之间其实没有区别，干掉。B说用品牌的cereals读cereal还是比较满意的，那就会降低这些客户会回来的可能性，先留着。C说这些人从来没想换品牌，原文说的是换了品牌的人，范围不一样，杀。D说价格问题，自主品牌的价格比品牌的价格要低，有点沾边，但是不能驳斥，杀。E说销售量没有增加，没说过，杀。
