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.
目标：To attract these consumers back 方案: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.
D项不能削弱是因为，提到store 的降价空间很大。但是并没有说可以降价到brand不能承受的地步，所以没能够削弱。A项，就是说，即使缩小差距也没用，还是贵啊，既然满意store的质量，可能就不会多花钱再买brand了。
