问题如下：
Holding the working-age population constant, if the labor force participation rate declines while the number of people employed remains unchanged, the unemployment rate will most likely:
选项：
A.remain unchanged. B.increase. C.decrease.解释：
For a given working-age population, a decline in the labor force participation rate (often caused by an increase in discouraged workers) reduces the labor force. If the number of people employed remains the same while the labor force becomes smaller, the number of workers defined to be unemployed must be smaller and thus the unemployment rate lower.
中文解析：
对于给定的劳动年龄人口，劳动力参与率的下降(通常是由于气馁的工人增加造成的)减少了劳动力。如果就业人数保持不变，而劳动力数量减少，那么被定义为失业的工人数量一定会减少，从而失业率会降低。
这题如果我通过失业率角度去想，分母劳动力减少，失业率不应该增加吗?
