Difficulty: Medium
Correct Answer: North
Explanation:
Introduction / Context:
We track heading through four right turns; the path actually returns to the start before the final leg completes.
Given Data / Assumptions:
Concept / Approach:
Each right rotates 90° clockwise. Track: N → E → S → W → N.
Step-by-Step Solution:
Verification / Alternative check:
Coordinate sum returns to (0, 0); heading remains the last move’s direction, North.
Why Other Options Are Wrong:
They contradict the rotation sequence.
Common Pitfalls:
Assuming “return to start” implies facing the original heading automatically—here it happens to match, but compute turns explicitly.
Final Answer:
North
