world have been faced with the problem of how to make their workers more
productive. Some experts claim the answer is to make jobs more varied. But do

Thus, although freedom of choice may be important, usually very little can be done to create it. Another important considera A. there are no ways to make workers more productive B. workers want more variety, freedom and money, but shorter working time and less contribution C. variety, freedom, contribution, more money and shorter working time seem possible factors leading to greater productivity, actually they are not or they are impossible D. it is impossible to make workers work more productively, because the work they do is so boring [单项选择]
