Difficulty: Easy
Correct Answer: South
Explanation:
Introduction / Context:
This problem checks basic direction-sense and turn handling on a grid. You must track orientation after each movement and left turn.
Given Data / Assumptions:
Concept / Approach:
Represent each move on standard compass axes (East–West as x-axis, North–South as y-axis). A left turn rotates heading 90 degrees counter-clockwise from current facing.
Step-by-Step Solution:
Verification / Alternative check:
List headings only: East → North → (left) West → (left) South. The final facing is South.
Why Other Options Are Wrong:
North/West/North-west misinterpret one or both left turns.
Common Pitfalls:
Confusing position with facing; the question asks for the current direction of travel, not where you are.
Final Answer:
South
