Final answer:
In gasoline-powered vehicles without a governor, the best practices include using only enough throttle to start moving, shifting to higher gears when possible, and engaging the clutch smoothly, hence 'd. All of the above' is correct.
Step-by-step explanation:
In gasoline-powered vehicles not equipped with a governor, the correct practice is to:
- Use only enough throttle to start the vehicle moving.
- Shift to higher gears as soon as you have the power to do so.
- Engage the clutch smoothly to avoid shock to the drive train, load, or passengers.
Therefore, the comprehensive answer is 'd. All of the above'. Adopting these practices will ensure smooth operation of the vehicle, better fuel economy, and reduced wear on the car's mechanical systems. Similar to how heat gained while cooking helps to prepare food, the heat released due to gasoline combustion enables a car to accelerate. It is crucial to manage how one engages with the vehicle's performance capabilities, as poor handling can lead to inefficient fuel use and increase the risk of wear and damage to components. In contrast to all-electric vehicles which have no emissions during driving, traditional gasoline vehicles require careful attention to how they are driven to maintain efficiency and reduce environmental impact.
