53.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 tmeporary employment to permanence emplyment.
本题答案是E。
但是我不理解书后面的解释:
the author says that the rise in temporary employment now far exceeds the level explainable by recent workforce entry rates of groups said to prefer temporary jobs. Thus, the number of workers employed on a temporary basis is far greater than the number of worker who actually do prefer temporary employment.
e:Correct. The passage indicates that the number of workers in temporary jobs was higher than the number of workers who stated a preference for tmeporary work.
