I gave my students this multiple choice question: Which is a way that a piece of paper can go through a chemical change?

Only one answer is correct among these 4 choices:
- fold the paper in half
- soak the paper in water
- burn the paper with fire
- cut the paper with scissors

Could you tell me which one is correct?
