问题 Questions are based on the following data.

In 1999 approximately how many of the temporary employees had an employment contract with a length of at most 3 months?
选项 A、185,000
B、150,000
C、101,000
D、35,000
E、19,000
答案A
解析 根据题意，此题需要计算1999年临时工中雇佣合同低于三个月的人数。计算需要两个量，一个是1999年临时工的总人数，根据左图，为286,000。另一个是低于三个月的比例，按照右图分类有两类，一个是少于一周的，另一个是一周到三个月的，共计12.3％+52.4％=64.7％，所以人数为286,000×64.7％=185,042，答案选A。
