问题如下：
Based on typical labor utilization patterns across the business cycle, productivity (output per hours worked) is most likely to be highest:
选项：
A.at the peak of a boom.
B.into a maturing expansion
C.at the bottom of a recession.
解释：
C is correct.
At the end of a recession, firms will run "lean production" to generate maximum output with the fewest number of workers.
考点: Resource Use Through The Business Cycle
解析：经济谷底时候，能力不行的员工都给干掉了，剩下的是工作效率较高的的精英。并且谷底时候，企业主通常尽可能让已有的劳动力多加班，这波人实在忙不过来了在招人呢。所以此时劳动生产率是最高的。
经济都不景气了为什么还要加班？
