The statement suggests that if a driver must leave the pavement due to a significant drop from the pavement edge to the shoulder, they should slow down and steer firmly. This is a safety recommendation typically associated with driver education, which falls under the broader category of Social Studies. The correct answer to the question is A. Steep Shoulder Drop. When driving, especially on highways or rural roads, encountering a steep shoulder drop can be dangerous. Drivers must reduce their speed and hold the steering wheel with a firm grip to maintain control of the vehicle.
