Apluralistic society guards against one group taking over by

having congress make laws
growing their population
defending constitutional rights
having the constant mix of diverse groups enter into politics

The answer is the last choice.  A pluralistic society is defined as having diverse beliefs but tolerating each other’s belief.  It is about maintaining cultural uniqueness. So in this situation, a pluralistic society guards against one group taking over by having the constant mix of diverse groups entering into politics.
