单项选择题
According to the law of diminishing returns, doubling the number of salespeople for a firm will most likely result in:（）
A. doubling the total sales of the firm.
B. more than doubling the total sales of the firm as a result of economies of scale.
C. increasing the total sales of the firm and reducing the average sales per salesperson.
答案
参考答案：C
解析：
The law of diminishing returns states that as more of a resource is added to a production process, holding other resource use constant, increases in output will eventually decrease. Therefore, as more salespeople are added they will generate more sales at a decreasing rate. Total sales will increase and the average sales per salesperson will decrease.
