Difficulty: Easy
Correct Answer: East
Explanation:
Introduction / Context:
The problem asks only for the final facing direction, not the final location. That lets us ignore distances for orientation and focus purely on left/right turns from the current heading.
Given Data / Assumptions:
Concept / Approach:
For orientation-only questions, apply each turn relative to the present heading. Right from East is South; left from South is East.
Step-by-Step Solution:
Initial: East.Right turn → South.Left turn → East.Final facing = East.
Verification / Alternative check:
Sketch a simple compass and rotate 90° at each instruction to confirm.
Why Other Options Are Wrong:
North/West/South do not match the left/right sequence applied from East.
Common Pitfalls:
Letting distances bias orientation; distances do not change facing.
Final Answer:
East
