Explanation:
The question asks what one should expect on an open highway that is not a common experience in a city or freeway. The correct answer is D. All of the above. When driving on an open highway, particularly in rural or less developed areas, drivers should anticipate conditions that are uncommon in urban settings. These include unmarked field or farm driveways, where vehicles might enter or exit the road unexpectedly, soft shoulders that can be hazardous if a vehicle needs to pull over, and livestock crossing areas, which are designated spots where animals such as cattle might cross the road. This variety of potential hazards underscores the importance of being vigilant and prepared for different driving conditions outside of urban centers.
