Answer 1

To answer your question, the class of levers that can increase the force to be applied is **Class 1 and Class 2** levers.

- **Class 1 levers** (e.g., a seesaw or a crowbar) can change the direction and apply a greater force depending on the position of the fulcrum.
- **Class 2 levers** (e.g., a wheelbarrow) always allow a smaller effort force to lift a larger load.

**So the correct response is: Class 1 and 2.**
