Directions (1 - 6) Study the following information and answer the questions given below:

Twelve people are sitting in two parallel rows containing six people each, in such a way that there is an equal distance between adjacent persons.

In row - 1 P, Q, R, S, T and V are seated and all of them are facing south. In row - 2 A, B, C, D, E and F are seated 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.

S sits third to the right of Q. Either S or Q sits at an extreme end of the line. The one who faces Q sits second to right of E. Two people sit between B and F. Neither B nor F sits at an extreme end of the line. The immediate neighbor of B faces the person who sits third to left of P. R and T are immediate neighbors of each other. C sits second to the left of A. T does not face the immediate neighbor of D.
