Answer:
Main idea of the passage: The woman sought a lavish lifestyle and was utterly discontented at her present living conditions.
Supporting detail: "She grieved over the shabbiness of her apartment, the dinginess of the walls, the worn-out appearance of the chairs, the ugliness of the draperies."
Explanation:
The woman being described in the excerpt was clearly grieved at her present state of living. She lacked contentment. The minor things she complained about were things which other women of her own class would barely notice. This shows that her concerns were frivolous.
She believed that she deserved a better lifestyle and would dream of that which she desired. Obviously, the woman wanted a wealthier life.
