q: what might someone need to mediate?
a. an argument on the playground between two students.
b. an injury to a little girl who fell off the playground slide.
c. a city plan to build a newer and nicer playground.
d. im not sure

Explanation:

To mediate means to help resolve a conflict or disagreement. An argument between two students is a conflict that would require mediation. An injury (option b) needs medical attention, a city plan (option c) involves planning/development, not mediation. So option a is correct.

Answer:

a. An argument on the playground between two students.
