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.
想知道D为什么不可以 我理解的是name-brand降价之后 store-brand还有空间可以降，所以算是对这个措施的一个weak。 提前谢谢回答的小伙伴啦
一种说法，D是无关项，因为可以lower到哪个程度完全没说，是否Lower到能够使plan失败也没说
另一种说法（更倾向），我觉得其实D是一个静态的绝对值的选项，题目说的是一个动态的相对值的情况。
好比我现在我和你都在跑步，我问你，”是否我跑的快些就能缩小我们之间的距离？”，你说：”因为你是男生，所以我跑得快”
讲得不好，望有所帮助
不觉得这种回答怪怪的吗？
“”因为你是男生，所以你跑得快”，手误
就是你降价我也降价呗，反正只要缩小或者跟你价格就行了，好像起不到真正削弱的作用
