What does mrs. sommers' plan for using the money to help the reader to understand about what kind of person she is?

you need need more details so we can understand what your asking us.

there purpose is to entertain

i do not see anyy sentence you are asking for me to read

i say that the right answer is: three personal subject pronouns. that’s because you will see “she” two times, referring to the librarian, and “they” one time, referring to the books. personal subject pronouns are used to replace common nouns or proper names.

the only possessive noun it’s present on the first sentence, when the speaker refers to “his” father.
