Final answer:
It is crucial to maintain your vehicle before driving on a rural highway due to the taxing terrain and limited help available in case of problems.
Explanation:
Maintaining your vehicle before setting out on a rural highway is critical because:
- Extreme terrain can tax your vehicle: Rough terrains, such as dirt or gravel roads, can put extra strain on your vehicle's suspension, tires, and other components.
- Help is far away in the event of a problem: Rural areas may have limited access to emergency services or auto shops, making it crucial to ensure your vehicle is in good condition before embarking on the journey.
Therefore, both options A and B are correct in this scenario.
