What should Karel do to avoid hitting an obstacle?

• A. Use commands to turn and then move
• B. Keep moving forward without stopping
• C. Only turn right
• D. Only use the pickBeeper() command

Answer: (A)

To avoid hitting an obstacle, Karel needs to use commands strategically to change direction before moving forward. By using commands to turn, Karel can navigate around obstacles instead of continuing in a straight path that leads directly to them. This proactive approach allows for a planned route rather than risking a collision. Keeping Karel moving forward without stopping can lead to hitting obstacles since Karel would be unaware of any obstacles in its direct path. Turning only right may not be sufficient, depending on the layout of the environment, as it might not provide the best route around obstacles. Additionally, the pickBeeper() command is irrelevant to maneuvering around obstacles, as it is used for collecting beepers rather than changing direction. Thus, employing turning commands in conjunction with forward movement is the most effective strategy for Karel to avoid hitting obstacles.
