I gave my students this multiple choice question: A company that makes fences started using a new material instead of wood. The new material will last longer than wood. What is the most likely benefit of the new material?

Only one answer is correct among these 4 choices:
- The new material will keep people safe.
- The new material will keep pets contained.
- The new material can make a yard attractive.
- The new material can save money on replacements.

Could you tell me which one is correct?
