Which of the following best completes the passage below? When the products of several competing suppliers are perceived by consumers to be essentially the same, classical economics predicts that price competition will reduce prices to the same minimal levels and all suppliers’ profits to the same minimal levels. Therefore, if classical economics is true, and given suppliers’ desire to make as much pro?t as possible, it should be expected that ______.
(A) in a crowded market widely differing prices will be charged for products that are essentially the same as each other(B) as a market becomes less crowded as suppliers leave, the pro?ts of the remaining suppliers will tend to decrease
(C) each supplier in a crowded market will try to convince consumers that its product differs signi?cantly from its competitors’ products.
(D) when consumers are unable to distinguish the products in a crowded market, consumers will judge that the higher-priced products are of higher quality
(E) suppliers in crowded markets will have more incentive to reduce prices and thus increase sales than to introduce innovations that would distinguish their product from their competitors’
products

答案是c

为什么c选项不算是在质疑P呢？这个题我是当成解释矛盾来做的，C一直想不明白....

谢谢！！！！

题干是说，竞争对手的同类商品在消费者眼里都是本质上差不多的，经济学上预测——价格竞争会让同质商品价格都降到最低，供应商的利润也都会降到最低。因此：供应商想要赚取更多利润该如何做?

C项说供应商努力让消费者相信自己产品的不同之处——也就是说扩大商品差异，由于差异化让自己的产品脱离同质产品，那也就不需要加入价格竞争，让利润跌到最低。

可是，"同类商品在消费者眼里本质上差不多“这个不是个事实吗？

是个事实没错，所以想增加利润就得让自己的商品和别的同类商品不同呢

LZ现在还没有理解清楚文章的逻辑
Which of the following best completes the passage below? When the products of several competing suppliers are perceived by consumers to be essentially the same, classical economics predicts that price competition will reduce prices to the same minimal levels and all suppliers’ profits to the same minimal levels. Therefore, if classical economics is true, and given suppliers’ desire to make as much pro?t as possible, it should be expected that ______.
(C) each supplier in a crowded market will try to convince consumers that its product differs signi?cantly from its competitors’ products.

第一句，前提：因：当products perceived to be same；果：price & profits will reduce to same minimal level，
第二句，在上一句的前提下，如果想要提升profits，应该怎么做

两句中的矛盾中心在profits，第一句讲在某种情况下，profits会缩减到最小，第二句想要追求profits最大，那么就要驳斥第一句的因，来达到相反的果
因是消费者认为各家的产品都是一样的，而C答案说拥挤市场中的supplier会说服消费者他们的产品是有差异化的，那么C提供了一个很好的驳斥角度，所以为正确选项。

另外看lz在上面的回复，你还需要理解when可以引导条件状语从句哦

谢谢，解释得很清楚我明白了，我之前没有把pc理出来。

这里的when引导的句子不是事实，只是一个假设而已。只有满足这个假设，即相互竞争的都是同类商品，才能得到后面的结论：导致这个市场价格最低和利润最低。
