In the following items, each passage consists of six sentences. The first sentence (S1) and the final sentence (S6) are given. The middle four sentences in each have been removed and jumbled up. These are labelled P, Q, R and S. You are required to find out the proper sequence of the four sentences and mark accordingly on the Answer Sheet. 

S1: Democracy, more than any other form of government, needs good citizenship. 
P: But it has to be freedom of service self-chosen and sometimes of sacrifice self-imposed. 
Q: Under absolutism or dictatorship, men are forced into line.
R: Freedom is the essence of democracy : the more complete the democracy, the more complete the freedom.  
S: But in a democracy things are not so simple.
