Answer 1

Energy can be lost due to friction during the process of pushing the box up the inclined plane. The relevant options for where energy can be lost include:

- **Friction between the box and the inclined plane** - This is a significant source of energy loss as the box moves up the incline, overcoming friction with the surface.

- **Friction between Lenore’s hands and the box** - There could also be energy lost here as she pushes the box.

While all these options can indeed result in energy loss, the most direct and significant one is typically **friction between the box and the inclined plane**.

Thus, the best answer would be: **Friction between the box and the inclined plane.**
