37. Editorialist: Drivers with a large number of demerit points(记作A) who additionally have been convicted of a serious driving-relative offense（记作B） should either be sentenced to jail （记作C）or be forced to receive driver reeducation（记作D）, since to do otherwise would be to allow a crime to go unpunished. Only if such drivers are likely to be made more responsible drivers（记作E） should driver re-education be recommended for them. Unfortunately, it is always almost impossible to make drivers with a large number of demerit points more responsible drivers.

根据文中的句子，现有的关系是

AB-〉C+ D（即AB-〉C，AB-〉D或者AB-〉CD）

D-〉E

A-〉E不成立

下面我们看看具体的选择项：

（A）AB-〉C，正确。因为如果AB-〉D成立，则AB->E成立，而这与A-〉E不成立矛盾，所以AB-〉D与AB-〉CD都不成立，所以选择项正确

（B）A-〉E，显然与已经条件矛盾，错误

（C）not(C+D)->allow a crime to go unpunished,文中并没有对两者的harsh进行展开或者比较

（D）not(B)->not(D),根据已经条件没有这个结论

（E）A和not(B)的交集->not(c)和D的交集，根据已经条件没有这个结论

我做的时侯就是先把A推出来然后就没有看下面的，也没有时间的说。总结来看，这种能用推导的题目一般第一个或者第二个就是答案。
