S, T, U, V, W, X, Y, and Z are seated in a straight line but not necessarily in the same order. Some of them are facing South while some are facing North. U sits fourth to left of Z. Z sits at one of the extreme ends of the line. Both the immediate neighbours of U face North. V sits second to left of T. T is not an immediate neighbor of U. Neither T nor W sits at the extreme end of the line. W faces opposite direction to X. Both the immediate neighbors of W face North. Y sits to immediate left of S. Immediate neighbours of X face opposite directions (i.e. if one neighbour of X faces North then the other faces South and vice-versa). Immediate neighbours of V face opposite directions (i.e. if one neighbor of V faces North then the other faces South and vice-versa). People sitting at the extreme ends face the opposite directions (i.e. if one person faces North then the other faces South and vice-versa). X faces to south direction.
