今日练习题为逻辑题，题目如下：
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 profit 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 profits of the remaining suppliers will tend to decrease
C each supplier in a crowded market will try to convince consumers that its product differs significantly 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
正确答案：
C
题目解析：
第一句说：竞争对手的相同商品在消费者眼里是essentially the same，然后用了个经济学解释。问题来了：供应商想要(desire)赚取更多利润该如何做?
A. 相同产品支付不同价格 - 与原文相悖的。错
B. 商家离开后，剩下的商家利润率会降。- 多余联想，思路偏到了说赚更多利润的点子上。错
C. 商家努力使消费者相信自己产品的不同之处 - 搞差异化竞争，由于差异化使的自己的产品不是同质产品，那也就不需要加入价格竞争跌到最低。对
D. D说的是消费者如何如何的行为，而问题问的是供应商该要做的事。错
E. 还要降价促销?那如何提高利润率? 错
