Step-by-step explanation:
Gerda's parents are in better spirits when they arrive in their ghetto apartment because it is a safe haven for them. The quote 'What a difference! what a difference! Someone to work for and live for--a home to bring comfort into' indicates that they are relieved to have a place to call their own and provide for their family.
