normally, increases in the price of a product decreases its sales except when the price increase accompanies an improvement in the product . wine is usual, however, often increase in the price of a particular producer's wine will result in increased sales ,even when the wine itself is unchanged. explain 其余选项都蛮白痴的 C consumers selecting wine in a store often use the price charged as their main guide to the wine's quality E Consumers who purchase wine generally have strong opinions about which wine they perfer 最后就徘徊在C E 之上了。 第一句是说,一般而言呢,价格升高了会使得出售的减少,除非是质量有所提高 第二句说,酒是很特别的,一个牌子的酒涨价后,即使酒本身没有变化,其销售量还是会升高的。 C 消费者将价格作为酒品质的代言。 言外之意是酒价格提高了,他们买了以后也。。。 但是这个却建立在一个assumption之上的,就是越高价格的酒,人们需求越多 D 人们对酒的品牌有所偏好。这个只能说明酒的销售量不变,但是不能说明sales提高了。 一个是建立在assumption之上,另一个。。。 答案给的是C。。。 牛牛们能不能解释一下呢~~或者对我对逻辑的分析有什么指教呢?谢谢啦~~ |
