Would these be good examples of hopelessness, hope, and realism in A raisin in the Sun

Question

1. hopelessness
Mama :Well whether they drinks it or not ain't none of
my business. But whether I go into business selling it
to 'em is, and I don't want that on my ledger this late
in life.
Mama is not only opposed to the idea of not investing but is also opposed to someone in her family selling liquor to the outside public.

2. Hope
Well, I always wanted me a garden like I used
to see sometimes at the back of the houses down home.
This plant is close as I ever got to having one.
Mama continues to hold on to her dream of someday owning her own home. In the meantime, she nurtures and cares for her plant as best she can.Dreams of buying a house, making some money in business, and going to medical school are dreams shared by millions of working-class Americans.

Realism
BENEATHA Oh, I probably will ... but first I'm going to
be a doctor, and George, for one, still thinks that's
pretty funny. I couldn't be bothered with that. I am
going to be a doctor and everybody around here better
understand that!
Her goal is also a hard one to reach because of discrimination against African American women during the time period in which the play takes place. Not many African-American women became doctors in the late 1950s.

If not, please help me

Answer 1

Mama disapproves of selling liquor, but that is not hopelessness. Mama does hope for a garden out back, yes. And I would qualify Beneatha's speech as hopeful, determined, and stating a reality as she sees it, so maybe realistic, but I'd qualify it more as hopeful and determined.

Answer 2

Hint: How would you characterize Ruthie's admonition to "Eat your eggs"?

Answer 3

It's been a long time since I read the play or saw it, but glancing through it, take a look at the "joking" way they talk about cockroaches. Is there anything hopeless there? It might be a joke, but there is hopelessness there. And pay careful attention to the last exchanges between Walter Lee, Ruth and Mama at the very end of Act I. Do you think Ruth's contemplation of an abortion expresses any hopelessness?
