It uses less water. It produces more heat. It releases less moisture. It absorbs more carbon dioxide.
I gave my students this multiple choice question: Many sports stadiums use grass, but some use fake grass called artificial turf. Artificial turf is made of fibers that look like real grass. In which way is this technology most likely beneficial?

Only one answer is correct among these 4 choices:
- It uses less water.
- It produces more heat.
- It releases less moisture.
- It absorbs more carbon dioxide.

Could you tell me which one is correct?

It uses less water.
