单项选择题
Which of the following statements is true
A．People cannot do without the wholesaler's function.
B．The function of the wholesaler does not add to the cost of goods.
C．The wholesaler helps to reduce the price of goods in shops.
D．The wholesaler is well paid for his commercial service.
答案
参考答案：D
解析：[分析] 是非题型。 答案出自第四段第一句话The wholesaler provides a purely commercial service, for which he is too well rewarded．A项的意思是人们离不开批发商，在第四段第三句提到one could eliminate the wholesaler，所以排除A。第二段第二行中提到批发商卖给零售商时价格提高了百分之几，第四段中有someone adding to the cost of goods，所以B和C也是错误的。
