  Read the following information carefully and answer the questions that follow: Twelve people are sitting in two parallel rows containing six people each, in such a way that three is equal distance between adjacent persons, in row-1 V, W, X, Y, Z and I are seated and all of them facing South. In row-2 P, Q, R, S, T and U are seated and all of them facing North. Therefore in the given seating arrangement each member seated in a row faces another member of the other row. Q sits third to the right of U. T sits to the immediate right of Q. Only one person sits between T and P. V is one of the immediate neighbours of the one who faces T. Y sits to the immediate left of V. Only three people sit between Y and I. X sits third to the left of W. W is not an immediate neighbor of I. S does not face X. Who amongst the following is facing R? Z        V     I       Y     X Four of the giv...
