To make the lever system more efficient, the best option would be:
**Use a stiffer lever to reduce energy lost bending the lever.**
By using a stiffer lever, you can minimize energy loss due to bending and deformation, which would improve overall efficiency. The other options may change the dynamics of how the lever is used but do not directly address increasing efficiency in the system itself.
