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?
Explanation
Choice B is the best answer. The sentence effectively explains an advantage of infilling: it’s less invasive than using a power grinder.
Choice A is incorrect. The sentence identifies a disadvantage of power grinding; it doesn’t explain an advantage of infilling. Choice C is incorrect. The sentence identifies the two techniques park rangers use; it doesn’t explain an advantage of infilling. Choice D is incorrect. The sentence indicates that power grinding and infilling are different in one aspect; it fails to explain an advantage of infilling.
