Final answer:
Using a helper when backing is important for safety, community, and comfort.
Step-by-step explanation:
When backing a vehicle, it is important to use a helper for several reasons.
- Blind spots: You have limited visibility when backing up, and there may be objects or people in your blind spots that you can't see. A helper can provide an extra set of eyes and alert you to any potential hazards.
- Job for someone else: By requesting someone to assist you with backing, you are providing them with a job, which can help foster a sense of community and goodwill.
- Comfort: Many people feel more comfortable and secure when a helper is present during backing, knowing that there is someone watching out for potential dangers.
Therefore, the correct answer is Option 4: All the above.
