13thOG38。 which of  the. Following best complete 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 level.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 suppliers in a crowded markert will try to convince consumers that it's products differs significantly from its competitors products
D when consumers are unable to distinguish the products in a crowded markert ,consumers will judge that the higher priced products are of higher quality
Esuppliers in a crowded markert 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，有点不理解，不是在背景里说了，完全竞争的市场，人们认为东西是一样的吗？为什么答案会说厂商让顾客相信 东西不一样？
谢谢

这个题目的Assumption 不是“完全竞争的市场，人们认为东西是一样的”，
而是“当市场存在竞争而消费者认为商品相差无几时，古典经济学预测价格会降到最低水平”
前者是一个简单句，后者是一个含条件的复合句；

题目第一句只是告诉我们在一个possible situation下会有什么后果，而这个possible situation 本身不一定发生；也正因如此，要避免价格被压低，生产商要力图避免消费者认为产品都一样这个possibility

一个日常生活中的例子：“当你不努力学习，你的成绩就下降”这句话并不是说你真的不努力学习，而是说在这个possible situation下后果是什么；同理，要避免成绩下降，就要努力学习
