Difficulty: Easy
Correct Answer: South
Explanation:
Introduction / Context:
This is a relative-position problem: you must visualize a simple coordinate layout and then compare two points. No distances are needed—only directions.
Given Data / Assumptions:
Concept / Approach:
Assign coordinates: Z = (0,0), Y = (0,1), X = (1,1). Since P is East of Z on the same row, P = (1,0). Compare P relative to X: vector from X to P is (1,0) − (1,1) = (0, −1).
Step-by-Step Solution:
Verification / Alternative check:
Sketch a 2×2 grid; the relationship is visually obvious: P is directly below X.
Why Other Options Are Wrong:
Common Pitfalls:
Mixing “direction of P from X” with “direction of X from P.” Direction is not symmetric.
Final Answer:
South
