RULE 1: All Socialist/Communist philosophers influenced by RL
RULE 2: None of the totalitarian supporters were influenced by RL

A. If a socialist political philosopher advocated a totalitarian state, he could not have been influenced by RL according to rule 2, however this violates Rule 1. Thus A is true.

B. Not necessarily. There could be other groups of philosophers who were neither socialist/communist nor non-supporters of totalitarian states.

C. We cannot infer this, there could have very well been other influences.

D. Not necessarily, there could have been other kinds of philosophers who were also influenced by RL.

E. Again there could be other groups.

Pick A.
