4. What has many teeth but cannot bite?

5. I am always in front of you but cannot be seen. What am I?

6. What can be broken, but never held?

7. The more you take away from me, the bigger I get. What am I?

8. What has one eye but cannot see?

9. I have keys but no locks, space but no rooms. What am I?

10. I go up and down the stairs without moving. What am I?
