1) Either “Ann takes a leave”, or “Ann quits her job’ 2) Tachnocomp does not find out---------allow her to take a leave 3) Technocomp finds out-------------------not allow her to take a leave 4) Conclusion: Ann quit her job----------Technocomp finds out Ann will quit her job, namely, she will not take a leave (according to 1) Technocomp finds out, namely, she will not be allowed to take a leave (according to 3) So the Conclusion is something like: Ann will not take a leave only if she is not allowed to take a leave “Ann will not take a leave” includes two possibilities: (1) ----- if Ann is not allowed to take a leave (2) ------if Ann is allowed to take a leave, but she does not it has to be assumed that (2) does not exist D 这道题目是很郁闷啊,我是用排除法做出来的. 考试的时候是不可能做上面这种推断的, 越推越糊涂 |
