I gave my students this multiple choice question: What is the best way to conserve natural resources in the home?

Only one answer is correct among these 4 choices:
- Throw all glass in the trash.
- Use paper towels to clean up spills.
- Shorten the time spent taking a shower.
- Water the lawn every day.

Could you tell me which one is correct?
