Why was Alvarez's mother fearful and silent,
despite living in the United States?

b. the poet identifies with private people.

    in the stanza, dickinson states she doesn't wish to seek fame and recognition from the public eye. nor is she afraid of authority figures, and you can definitely tell she isn't hiding something. more as she identifies with private people, who are not known by the community

i would say a because the main idea is what the author is the point the author is trying to get across.

it would be c. guilty
