What does the command 'turnAround()' do?

• A. Karel turns 90 degrees
• B. Karel turns 180 degrees
• C. Karel turns left 90 degrees
• D. Karel turns right 90 degrees

Answer: (B)

The command 'turnAround()' instructs Karel to rotate 180 degrees. This means that after executing this command, Karel will be facing the opposite direction from where it originally was. The action of turning around is essential for navigating back along the path or moving away from obstacles. While turning 90 degrees left or right would only change Karel's orientation by a quarter of the circle, turning around requires a complete half-circle turn. Understanding this command is important for programming Karel's movements effectively, especially when Karel needs to return to a position or adjust its direction significantly.
