求问一道狒狒逻辑67. China has a factional political system.

Emmayeli

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.

B.        All factional political systems are closed political systems.  
换句话说就 : 不一定所有的closed 都是 factional ，这就是数学题啊  closed集合大于等于factional 的集合
C.        All closed political systems are factional political systems .
这说所有closed都是factional ...而China是closed ..所以China一定是factional
