Which excerpt from "A Poem for My Librarian, Mrs. Long” best supports the conclusion that books gave the poem’s speaker a sense of comfort and hope during her childhood? There was a bookstore uptown on gay street
Which I visited and inhaled that wonderful odor
Even today I read hardcover as a preference paperback only
As a last resort
And up the hill on vine street
(The main black corridor) sat our carnegie library
Mrs. Long always glad to see you
But no lions or witches scared me
I went through
Knowing there would be
Spring
