What are some possible reasons eva's decision to go downstairs and light the fire, "the smoke of which was in her hair for years"? how does this make you feel about her character? was this an act of sacrifice or selfishness? can eva be described as "good" or "bad"?

It was an act of sacrifice and she is a good person.

Explanation:

The smoke not the fire has been in her hair for years, meaning that the issue has been on with out her knowledge of it. The narrator of the event is rather selfish and a bad person. The narrator is aware that she was not aware of the smoke in her hair and she made every frantic effort to go and light the fire. Hers is a selfless service to others

ok if it wasn't the hans one it was probably c or he thought the mountain was collapsing on them.
