读了lawyer和ethyl的观点,我还是对B有疑问: 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. 这句话说明:wide price gap导致consumers switching,而至于quality,因为句子中有reputation,所以有两种可能性:第一种、switching的consumer知道store-brand的cereal质量上的确不如name-brand因为巨大的price gap所以switch了;第二种、switching的consumer发现所谓better quality其实根本就不是想象当中那么好(也就是说实际质量可能差不多) 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.这句话说明plan of action:缩小price gap来吸引consumer back 在上面的第一种情况下: B.generally been satisfied并不表示store-brand和named-brand没有质量差距,B需要有一个assmption:consumer只要对>=generally satisfied态度都是一样的 D.因为有significant lower price,因此存在这种可能性:无论name-brand的manufacturers无论如何降价也不能trigger switching(这时取决于consumer更看重price还是quality) 在上面的第二种情况下: B.五年前发现quality就是这样,五年后也不会有什么变化,也就只能看price D.因为质量不变,只有price这个变量,所以同样存在上面D的可能性。 个人觉得如果说D不好的原因是因为它并未明确表示出这是五年前到现在还是五年后,但是因为题干中有reputation,我觉得偏向于第二种情况。 请大家指点 |
