Concept:Arrange houses from left to right based on relative positions.
Explanation:• "P is right of Q" means Q is left of P. So order: Q ... P.
• "T is left of R and right of P" means P is left of T, and T is left of R. So order: P ... T ... R.
• "Q is right of S" means S is left of Q. So order: S ... Q.
• Combine all: S left of Q, then Q left of P, then P left of T, then T left of R. Final order: S, Q, P, T, R.
• With 5 houses, the middle (third) is P.
