Question

select the word from the drop - down menu that best completes the sentence. after listening to each party’s claims, the choose... proposed a reasonable compromise. the drop - down menu options are: mediate, mediation, mediator, mediatory

Explanation:

The sentence structure requires a subject (a noun) that performs the action of proposing a compromise after listening to claims. "Mediator" is a noun referring to a person who mediates (facilitates resolution between parties), fitting the context. "Mediate" is a verb, "mediation" is a noun for the process, and "mediatory" is an adjective, so they don't fit as the subject here.

Answer:

mediator
