While researching a topic, a student has taken the following notes:

* Some sandstone arches in Utah's Arches National Park have been defaced by tourists' carvings.
* Park rangers can smooth away some carvings using power grinders.
* For deep carvings, power grinding is not always feasible because it can greatly alter or damage the rock.
* Park rangers can use an infilling technique, which involves filling in carvings with ground sandstone and a bonding agent.
* This technique is minimally invasive.

The student wants to explain an advantage of the infilling technique. Which choice most effectively uses relevant information from the notes to accomplish this goal?
