If a person walked straight from a point, then turned left, walked straight, then turned right, and after walking straight, found himself walking towards the South, in which direction did he start walking?
Correct: C
Let's trace the path backward:
1. Final direction: South.
2. Before this, he turned right. If a right turn led him to face South, then he must have been facing East before the turn.
3. Before that, he turned left. If a left turn led him to face East, then he must have been facing North before the turn.
4. He walked straight from a point and then turned left. So, his initial walking direction was North.
Therefore, he started walking towards the North.
