Answer:
her
Explanation:
a pronoun just substutes a specfic names or nouns, instead of "Stacy took Stacy's book off the shlef" you would say "Stacy took her book of the self."
I would say that "constant cry" and "Chesterton's cat" are the obvious ones. However "echoed in our ears" is a pretty subtle one that you can definitely make a solid argument for.
