单项选择题
Which of the following factors is least likely to affect the supply of labor（）
A. Wages offered.
B. The aggregate requirement for labor.
C. The size of the adult population.
答案
参考答案：B
解析：
Wages, the size of the adult population ( i. e. the available labor force) , and the accumulation of capital are all factors that affect the supply of labor. The aggregate requirement for labor is a demand issue that will ultimately help to determine the equilibrium level of wages and quantities offered.
