23. 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 going on 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.
THE answer is C,I think it‘s irrelevant with the context,why not D,waiting for NN,thanks
我选的E
等牛人扫盲......
原文推理:not strike---->increase wage----->sell off subsidiaries。结论:sell off subdidiaries
从上面逻辑链可看出要推出结论,必须假设not strike 或increase wages。
我学的TESTMASTER专门介绍过此类题,即有IF,UNLESS这类逻辑关联词的题目的做题方法,就是用形式逻辑的方法去推,严格按照题目给出的形式列出逻辑命题,再按逆否啊之类的方法去推。
用这个方法的话,肯定是C。其他都是无关的
把C取非,即The workers at Bell Manufacturing will be going on strike---》not increase wage----》not sell subsidiaries,原文结论sell subsidiaries,这个还能被看作削弱结论吗?还是完全与结论对立了?
strike简称为:S
increase wages:简称为I
sell subsidies 简称为:su
根据条件:IF非I 则S 这一命题的逆否命题为:IF非S 则I(学过形式逻辑没?没学过的补一下,很简单的)
IFI 则SU
所以可推出 IF 非S,则SU
选C
谢了,大律师,每次都非常耐心得讲解,以前只知道假设肯定是结论得必要条件,至于充分型,必要型没怎么注意过,又学到一样,非常感谢
也谢谢晓梦
