To improve the efficiency of a ramp, the most effective options from the ones you provided would be:

1. **Smooth the surface**: A smoother surface will reduce friction, making it easier to move objects up and down the ramp. This can significantly improve performance, especially for wheeled vehicles or loads.

2. **Add a rough surface**: This would actually decrease efficiency for certain applications (like wheeled transport), as added friction could make it harder to move items. A rough surface may be beneficial in preventing slipping for foot traffic or certain materials, but not for overall efficiency in transporting loads.

3. **Insulate the surface with foam**: While insulating a ramp might provide benefits in terms of temperature regulation or user comfort, it typically wouldn’t improve the mechanical efficiency of the ramp itself in terms of load movement.

4. **Make it shorter and steeper**: This could result in a ramp that takes less space, but a steeper ramp can be harder to navigate, especially with heavier loads, causing more strain and increasing the likelihood of failure or accidents.

In conclusion, **smoothing the surface** would be the primary factor in improving ramp efficiency in most scenarios, whereas the other options may not yield the desired improvements or could potentially reduce efficiency in specific cases.
