Explanation:

The root "medi" means "middle". When mediating, one acts as a middle - person between two sides (like in an argument). The other options: "the scientific study of mountain peaks" has no relation to "middle", "to award a prize" and "to teach a class" also do not involve the concept of being in the middle between two entities.

Answer:

to settle an argument between two sides
