What are the arrangements Socrates suggests for the housing and compensation (pay) of the
guardians and of the auxiliaries? For what reason(s) does he favor such arrangements?

you should look at the context in which this suggestion comes up. Doing this would be the best
way to figure out the reasons for the arrangements.
