67. It has always been difficult to understand the basis of politics in the People’s Republic of China. Because the system is effectively closed, it is impossible to know with any degree of confidence who is allied with whom and for what reasons. Yet Chinese politics does exhibit many of the external characteristics of factional political systems, as found in more open societies. It is legitimate to conclude, therefore, that China has a factional political system.

Which one of the following, if true, would confirm the author’s conclusion that China has a factional political system?          

A.       All open political systems are factional political systems.

B.       All factional political systems are closed political systems.

C.       All closed political systems are factional political systems.

D.       China’s political system is more open than many existing factional political systems.

E.        China’s political system is more closed than all existing factional political systems.

答案：C

思路：加强题。前提1，(A)中国政治系统——封闭；前提2，中国政治——派系政治系统；结论，(B)中国——派系政治系统。加强结论。

A.       open political systems 文中未提及，与open societies无关，不要混淆。

B.       B是A，AB之间架桥，但起到加强前提的作用，与问题要求相反。

C.       A是B，AB之间架桥，起到加强结论的作用，

D.       架桥方向错误，open与否与结论无关。

E.        同D。

“官方”解释如上，可是细看题目，题目是因果关系

. Because the system is effectively closed, it is impossible to know with any degree of confidence who is allied with whom and for what reasons. Yet Chinese politics does exhibit many of the external characteristics of factional political systems, as found in more open societies. It is legitimate to conclude, therefore, that China has a factional political system

尝试翻译：因为系统有效封闭，所以不能确定谁和谁联合以及为什么。但是，中国政治没有显示出多少派系政治系统的外部特点，和在开放的社会中发现的是一样的。所以，中国是派系政治系统。

这是什么推理过程啊？大家帮帮忙~~我怎么推不出 “前提1，(A)中国政治系统——封闭；前提2，中国政治——派系政治系统；结论，(B)中国——派系政治系统。加强结论”……
