GWD5-29对参考答案的疑惑

Q29:

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.

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?

1. There is no significant difference among manufacturers of name-brand cereals in the prices they charge for their products.
       
2. Consumers who have switched to store-brand cereals have generally been satisfied with the quality of those cereals.
       
3. Many consumers would never think of switching to store-brand cereals because they believe the name brand cereals to be of better quality.
       
4. 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.
       
5. Total annual sales of cereals—including both name-brand and store-brand cereals—have not increased significantly over the past five years.
   
         

参考答案是B,之前的讨论贴中很多大N都支持B,但我觉得B错,只有D对.

原文说:plan to narrow the price gap between their cereals and store brands to less than what it was five years ago. 由于D提供了一种可能:你降价我也降价,所以你无法把price gap缩小到比以前更小,原计划目标无法成功.

B无关,因为原文前提已经说了质量并非影响购买因素.

请大家讨论!

原文说:
            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 ,后面又说目标是plan to narrow the price gap between their cereals and store brands to less than what it was five years ago,只说到gap的扩大和缩小,没说到具体各自价格数是多少,MM说到doesn't indicate how much more expensive,这已经miss the point了呀.不管贵多少,只要gap能缩小就行了,至于这gap具体是多少数字,对gap能否缩小没影响.

另外MM对B的解释我看不太懂,不过好象没有说到关于gap的问题.

这里我觉得MM有一个想法就是:用你自己认为什么在影响购买力的常识去评估原文的计划,而不是就原文的计划本身可不可行进行评估.

版版能说说对B为何不对的看法吗?

我只能选自己觉得对的，没法说什么到底什么不对。只是读题目，看自己的自然逻辑。

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?

问题是问，下面那个咚咚如果是真的，那么生产商的计划很难实现 － 什么计划呢？大降价

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.

因为成本问题，所以店牌子的咚咚成本非常低。

所以，生产商没法大杀价格。

所以，计划没法实现。

所以我才发贴请大家讨论呀.但是,GMAT考试时只有一个正确答案,考试时是没人跟我讨论的.我是想从考试时的角度出发,请大家看看错误选项它的什么地方必然站不住脚?
