Study the following information to answer the given questions. 
Eight people are sitting in two parallel rows containing four people each, in such a way that there is an equal distance between adjacent persons. In row 1 A, B, C and D are seated (but not necessarily in the same order) and all of them are facing south. In row 2 P, Q, R and S are seated (but not necessarily in the same order) and all of them are facing north. Therefore, in the given seating arrangement each member seated in a row faces another member of the other row.
R sits second to the left of the person who faces A. S is an immediate neighbour of R. Only one person sits between A and D. One of the immediate neighbours of C faces Q. B does not sit at any of the extreme ends of the line.
