The workers at Bell Manufacturing will shortly go on strike unless the management increases their wages. As Bell's president is well aware, however, in order to increase the worker's wages, Bell would have to sell off some of its subsidiaries. So, some of Bell's subsidiaries will be sold.　　The conclusion above is properly drawn if which one of the following is assumed？　　（A） Bell Manufacturing will begin to suffer increased losses.　　（B） Bell's management will refuse to increase its worker's wages.　　（C） The workers at Bell Manufacturing will not be goingon strike.　　（D） Bell's president has the authority to offer the workers their desired wage increase.　　（E） Bell's workers will not accept a package of improved benefits in place of their desired wage increase.CDE困惑到我了…求分析~！

这一类题目的话，总是可以把unless看成if not，所以总结一下题目条件就是
1） if not increase wages --> workers strike   由原命题成立逆否命题必成立可得出  workers not strike --> increase wages
2） if increase wages -->  sell off subsidiaries

1)+2)可推出workers not strike --> increase wages -->  sell off subsidiaries
所以要推出some of Bell's subsidiaries will be sold，可以通过assume “workers not strike”，亦即C。
D属于无关选项，president有无authority跟以上的逻辑链没有任何关系。E也是无关选项，workers肯或不肯接受其他package跟以上这个逻辑链也没有任何关系。
