S, T, U, V, W, X, Y, and Z are seated in a straight line with equal spacing but not necessarily in the given order. Some face north, others south. Facing the same direction means both face north or both face south; facing opposite means one faces north and the other south.

• Only two people sit to the right of S.
• T sits third to the left of S.
• Exactly one person sits between T and X.
• X sits immediately to the right of W.
• Exactly one person sits between W and Z.
• Both immediate neighbors of T face the same direction.
• U sits third to the left of X.
• T faces opposite to S.
• Y is not seated at either end of the line.
• V faces the same direction as W.
• Both Y and U face opposite direction to Z.
