Some observers have attributed the dramatic growth in temporary employment that occurred in the United States during the 1980s to increased participation in the workforce by certain groups, such as first-time or reentering workers, who supposedly prefer such arrangements. However, statistical analyses reveal that demographic changes in the workforce did not correlate with variations in the total number of temporary workers. Instead, these analyses suggest that factors affecting employers account for the rise in temporary employment. One factor is product demand: temporary employment is favored by employers who are adapting to fluctuating demand for products while at the same time seeking to reduce overall labor costs. Another factor is labor’s reduced bargaining strength, which allows employers more control over the terms of employment. Given the analyses, which reveal that growth in temporary employment now far exceeds the level explainable by recent workforce entry rates of groups said to prefer temporary jobs, firms should be discouraged from creating excessive numbers of temporary positions. Government policymakers should consider mandating benefit coverage for temporary employees, promoting pay equity between temporary and permanent workers, assisting labor unions in organizing temporary workers, and encouraging firms to assign temporary jobs primarily to employees who explicitly indicate that preference.
The passage suggests which of the following about the workers who took temporary jobs during the 1980s? A.Their jobs frequently led to permanent positions within firms. B.They constituted a less demographically diverse group than has been suggested. C.They were occasionally involved in actions organized by labor unions. D.Their pay declined during the decade in comparison with the pay of permanent employees. E.They did not necessarily prefer temporary employment to permanent employment.
D, 文中没有提到的。
E, 文中有两处内容，在暗示：
1. Another factor is labor’s reduced bargaining strength, which allows employers more control over the terms of employment. 这里说明临时的工作者没有什么议价能力。
2. promoting pay equity between temporary and permanent workers 这里暗示临时工和长期合同工之间存在收入差。
另外，你提到的他们喜欢去做临时工，such as first-time or reentering workers, who supposedly prefer such arrangements. 后面有However，说并不一定对。在后面的factors就明白了，其实他们不是自愿的。
BTW，我不是什么大N. 我也刚做完这个阅读，记忆犹新。
