(单选题)

The problem of unemployment will arise ______.

A.if the minimum wage is set too high

B.if the minimum wage is set too low

C.if the workers are unskilled

D.if the maximum wage is set

参考答案：A

参考解析：

细节理解题。根据第二段第四至七句“However, if the minimum is high, employers may hire fewer workers. They will replace workers with machinery. Therefore, other things being equal, the number of workers that employers want decreases. Thus, critics hold the opinion that an increase in the minimum wage may cause unemployment”可知，最低工资如果设定过高，公司会聘用更少的员工，他们会用机器代替人工。因此，最低工资如果设定过高，失业率会上升。B、C、D均与文意不符。故选A。
