OG-148，不懂

why not c?

C不是说COST增加么？而题目说COST增加利润提高。而B，整句话什么意思？The retailer’s customer base 由哪钟人组成，有关系么？请教NN啊。。。

题干：雇员的工资提高→销售商成本增加，为什么利润也增加？

选项B：雇员的工资提高→销售商收入增加（因为雇员也是销售商的顾客）

以下是引用祈晴坊主在2003-7-9 22:36:00的发言：
148. A discount retailer of basic household necessities employs thousands of people and pays most of them at the minimum wage rate. Yet following a federally mandated increase of the minimum wage rate that increased the retailer’s operating costs considerably, the retailer’s profits increased markedly.
Which of the following, if true, most helps to resolve the apparent paradox?

(A) Over half of the retailer’s operating costs consist of payroll expenditures; yet only a small percentage of those expenditures go to pay management salaries.
(B) The retailer’s customer base is made up primarily of people who earn, or who depend on the earnings of others who earn, the minimum wage.
(C) The retailer’s operating costs, other than wages, increased substantially after the
increase in the minimum wage rate went into effect.
(D) When the increase in the minimum wage rate went into effect, the retailer also raised the age rate for employees who had been earning just above minimum wage.
(E) The majority of the retailer’s employees work as cashiers, and most cashiers are paid the minimum wage.
对题目有说道工资要增加，但是答案B那里说明工资要增加？？？而C说到了operation cost要增加不是与题目“increased the retailer’s operating costs considerably, the retailer’s profits increased markedly.“中一个意思么？

请教啊。。。。。

本题要求的就是解决 increased the retailer’s operating costs considerably, the retailer’s profits increased markedly.的自相矛盾. C中说operating costs increased substantially 是和题目一致的,并没有解决矛盾.不能选. B中说零售商的客户主要是由挣最低工资或由依靠挣最低工资的人组成.题目中说挣最低工资的人工资增加,也就是说B中的客户群的工资增加,那么他们就可以买相对多的basic household necessities,所以零售商的销售额增加,他的利润就增加.

不知我说明白没?
