Answer 1

To improve the efficiency of a lever system that is only 30% efficient, the most effective option from the given responses would be to **use a stiffer lever to reduce energy lost bending the lever**. This would minimize energy losses due to deformation and make the system more efficient.

While making a longer lever may also reduce the amount of force needed to lift a load, it does not inherently increase the efficiency of the system relative to energy loss. Additionally, using it with a lighter load may make it easier to lift but does not address efficiency directly. Therefore, the stiff lever option stands out as the best choice for enhancing efficiency.
